Using Report Viewer with Dataset Asp.net Csharp and vb

For Using Report Viewer in Asp.net or Desktop Application using Csharp or Visual basic I am today providing a simple step by step solution -

Demo File is also available to Download so that you can have a demo for how to use or Use Reports With Dataset in Asp.net . I have provided Both Csharp and Vb code

Step 1 - First of Start a C# Project or Vb Project and then Add an Empty Webform to it .

Step 2 :- Now Right Click on Solution in Solution Explorer and Click on Add then click on New Item . Then Click On DataSet and Give a Name and Click Ok . This will add a Dataset in your Project . I will recommend it give dataset a name similar to database table whose data you want to show in Report Viewer

Step 13:-  Now we need to Add the Code so Open Cshar Code side of Webpage where you have added the Report viewer control And Add the following code according to your choose language c# or vb

Now At Page_Load Event of your WebPage Add the Following Code According to C# or VB


Imports System.Data
Imports System.Data.SqlClient
Imports Microsoft.Reporting.WebForms

        'VB CODE
        ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc")

        Dim dsUsersInfo As New DataSet1
        Dim con As New SqlConnection("Your Connection String")
        Dim cmd As New SqlCommand("select * from YourTableName", con)
        Dim da As New SqlDataAdapter()
        da.SelectCommand = cmd

        'DataTable1 is the DataTable we have created in Dataset1 that contains our columns
        da.Fill(dsUsersInfo, "DataTable1")


        Dim datasource As New ReportDataSource("DataSet1", dsUsersInfo)
        ReportViewer1.LocalReport.DataSources.Clear()
        ReportViewer1.LocalReport.DataSources.Add(datasource)


        'CSharp Code
        'ReportViewer1.ProcessingMode = Microsoft.Reporting.WebForms.ProcessingMode.Local
        'ReportViewer1.LocalReport.ReportPath = Server.MapPath("~/Report.rdlc")

        ' DataSet1 dsUsersInfo = new DataSet1();

        '        SqlConnection con = new SqlConnection("Your Connection String"));

        '            con.Open();
        '            SqlCommand cmd1 = new SqlCommand("select * from TableName", con);

        '            SqlDataAdapter da = new SqlDataAdapter(cmd1);
        '            da.Fill(dsUsersInfo, "DataTable1");
        '            con.Close();

        '        ReportDataSource datasource = new ReportDataSource("DataSet1", dsUsersInfo.Tables[0]);

        'ReportViewer1.LocalReport.DataSources.Clear()
        'ReportViewer1.LocalReport.DataSources.Add(datasource)




Step 12 :- Now when you run the Page where you have added the Report viewer control It will show the Report with data from database

Advantage of Asp.Net MVC

Asp.net  is a part of .net platform for creating,building, deploying and running web applications using C#,VB etc .we can develop a web application by using Asp.Net Web Form and Asp.Net MVC. Asp.Net MVC is advanced technology that is most widely used nowadays . MVC is a great thing available for developers that makes work of developers easy and more flexible .

MVC stands for Model-View-Controller . MVC separates the code in 3 different things that make the code cleaner , flexible and easy to understand and modify . So Today I am going to tell some of big advantages or some good things that Asp.Net MVC provides as compared to Web-forms . This is not a comparison of Web-forms and MVC this is just overview or advantages or features that Asp.Net mvc provides us

1. Rapid Application Development ( RAD ) :- So first I will start with biggest advantage of Asp.net Mvc and this is the thing that is most in demand in Enterprises and everywhere in development area . This is Rapid application development . Asp.Net MVC provides Database First Approach for developing WebApplications . This approach is used with Scanfolding Technique this technique is like a magic provided in Asp.Net MVC . Scanfolding technique tells if you have designed your database in good manner that means if you have Created Normalized Database with all like Primary keys, foreign keys ,One-many , many-many relationships then you need not to do more effort for developing rest on your application in Asp.Net MVC Rest of things will be created with less efforts using scanfolding . With Asp.Net MVC you can have your simple basic website ready within 1 minute after you created your Database . So that was explanation to RAD in Asp.Net MVC

In Pic below we are choosing MVC5 scanfolding template


Then it automatically generate code for us

2. Partial Layouts :- In Asp.Net we ofter use User controls that were used for code reusability we create a user control then where we require that type of code that we coded in user control we call that user control there . In similar way Partial Layouts is provided in Asp.Net MVC .Partial Layouts are very useful things provided in Asp.Net MVC . Partial Layouts are like Master Pages that we use in Asp.Net web-forms . These are used as master pages or master layouts that can be called in any view in Asp.Net MVC . Like in php we use include ( "partialheader.php" ); to include some header in all pages or some specific pages so instead of writting that code in all pages we call then there . Similar in Asp.Net Web-Forms We use content placeholders and contentplaceholders are placed in Master Pages and when we call these master pages and use then in child forms then code of child forms is placed in content placeholder area In the similar way Partial layout works . The partial layout contains @Renderbody in Razor view then replace the child page or code of  page that is calling it

3. MVC Is  Stateless : Asp.Net was Statefull by using viewstates or sessions but Asp.net MVC is stateless . It will be wrong to say mvc is stateless it would say http is stateless . By stateless i mean there is nothing in http that holds the user session or that record the activity of user when user logged in etc so this was maintained or state was maintained using viewstate and sessions . This was used in asp.net Webforms because they contain server controls that contains viewstate and that postback the values and update viewstates But there is not server controls in Asp.Net MVC So it does not maintain states . It has divided the code in three patterns model-view-controller that handles everything That's why it says MVC is stateless But in actual http is stateless that why MVC is stateless

4. No Events : As we came to know there are no server controls in Asp.Net MVC so there are no events for any control as there are not server controls All this is handled by connection of controllers with views where views hold your html code or designing code and controller hold your logics code .

Implementing Search Functionality in ASP.NET MVC 4

What we are Going To cover

* In this Tutrial we are going to cover how to implement search functionality in Asp.Net MVC 4 . In our web applications in MVC we often need to add the functionality to search the database objects for specific data based on some creteria like to find employees with name starting with 'N' or to find data of employees that have Gender Male

Download Demo App With Database Link Below

Creating Database For This Application

1. First create Database

* Open Microsoft Sql server . Click on New Query . Now execute the query below to create database

Create Database searchingInmvc

(
ID int identity primary key,
Name nvarchar(50),
Gender nvarchar(50),
Email nvarchar(50)
)

Creating Table In database 

//Inserting Demo Data

Here , we are inserting 4  Rows in Database table

insert into tblEmployee values('John','Female','john@geeksprogrammings.blogspot.in')
insert into tblEmployee values('funky','Male','funky@geeksprogrammings.blogspot.in')
insert into tblEmployee values('wiley','Male','wiley@geeksprogrammings.blogspot.in')
insert into tblEmployee values('ceren','Female','ceren@geeksprogrammings.blogspot.in')

Inserting Data in Table 

Showing All Inserted Data

Download Database script file

In link below you can download the script file and then double click on file it will open in sql server . It will create the database automatically for you when you execute it

Create New MVC 4 Application in Visual Studio

1. Start Visual Studio with language selected as C#
2.Click on File --> Then click on New Project
3. Scroll down and select ASP.NET MVC 4 Web Application

4. Give appropriate Name,Path and solution Name and Hit Enter
5. choose Empty Template
6. Choose Razor View Engine and Hit Enter
7. Now New MVC 4 web application is started

Adding Models to MVC 4 Application

1. In solution Explorer -- > Right click on Models --> Then click on New item



2. Then select ADO.NET Entity Data Model --.> Give it a valid name like 'sampledatamodel'
3. Click Add

Implementing Search Functionality in Asp.Net MVC 4

4. Now A dialog box appears choose database connection to sql server and give your connection string a name that will be give to connection string in web.config file

Implementing Search Functionality in Asp.Net MVC 4

5. click next
6. Now in next dialog box you will be presented with tables available in database table select you table

9. Now Model is successfully Added

Adding Controller and Views To MVC 4 Application

To add controller to database --

1. Right click on Controllers folder in solution folder
2. click on Add --> Then click on Controller

Implementing Search Functionality in Asp.Net MVC 4

3. Now Add controller Dialog Box appears
4. Give your controller a name like 'HomeController'
5. In template choose  'MVC controller with read/write and views using Entity  Framework'
6. The Reason behind choosing this is it will automatically generate some pages to insert,delete , update data of model to which we are associating this controller
7. Now give the Model name that we have added in previous step 'Employee'
8. Now Choose dbcontext class from dropdown menu and finally  click ADD
9. This autimatically add Views for insert , update, delete and index view in views folder under controller named folder

Implementing Search Functionality in Asp.Net MVC 4

 10. Now Run your application . This will give output below:-

Implementing Search Functionality in Asp.Net MVC 4

Adding Style And Look To Application

So we are going to search the database and retrieve data from database and then show the retrieved result to user. For this we have to get some controls and code . The GUI design that are going to give to this application is as below :-

1. In solution Explorer under Index view Double click on Index.cshtml

2. Now just before the line '<h2>Index</h2>' add a line 

<div style='font-family:Arial'>

and close this div right below the code after table tag 

Other UpdationAre in Demo Project Downlao And Use it

3. Update your Index.cshtml file under view folder in solution Explorer with the code below

@model IEnumerable<SearchInMVC.Models.Employee>

@{

    ViewBag.Title = "Index";

}

<div style="font-family:Arial ">

<h2>Index</h2>

<p>

    @Html.ActionLink("Create New", "Create")

</p>

<p>

@using (Html.BeginForm ("Index","Home",FormMethod.Get ))

{

<b>Search by:</b>@Html.RadioButton("searchBy","Name")<text> Name</text>

@Html.RadioButton("searchBy","Gender")<text>Gender</text><br />

@Html.TextBox("Search");<input type="submit" value="Search" />

    }

</p>

<table border="1">

    <tr>

        <th>

            @Html.DisplayNameFor(model => model.Name)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.Gender)

        </th>

        <th>

            @Html.DisplayNameFor(model => model.Email)

        </th>

        <th>Action</th>

    </tr>

    @if (Model.Count() == 0)

    {

        <tr>

        <td colspan ="4">No Rows Match Search Criteria</td>

        

        </tr>

    }

    else

    {

foreach (var item in Model)

{

    <tr>

        <td>

            @Html.DisplayFor(modelItem => item.Name)

        </td>

        <td>

            @Html.DisplayFor(modelItem => item.Gender)

        </td>

        <td>

            @Html.DisplayFor(modelItem => item.Email)

        </td>

        <td>

            @Html.ActionLink("Edit", "Edit", new { id = item.ID }) |

            @Html.ActionLink("Details", "Details", new { id = item.ID }) |

            @Html.ActionLink("Delete", "Delete", new { id = item.ID })

        </td>

    </tr>

}

    }

</table>

</div>

Now Run your Application and you can see the change with output below :-

Implementing Search Functionality in Asp.Net MVC 4

Code Description

In code above we have used Razor code and instead of using <form> tag that we usually use in html we have used Html Helper below

@using (Html.BeginForm ("Index","Home",FormMethod.Get ))

{

<b>Search by:</b>@Html.RadioButton("searchBy","Name")<text> Name</text>

@Html.RadioButton("searchBy","Gender")<text>Gender</text><br />

@Html.TextBox("Search");<input type="submit" value="Search" />

    }

In Html.BeginForm ("Index","Home",FormMethod.Get )

Here, Html.BeginForm  is used in place of using form tag . Html.BeginForm  Received 3 arguments .

Here, "Index" is Name of action that will be executed on posting form  to server

Here, "Home" is name of controller to which this link will be redirected when clicked

Here, " FormMethod.Get" type of encoding method that applied on data we are posting 

Now Open Controller And Add code below to Index Action of home controller

 if (searchby == "Gender")

            {

                return View(db.Employees.Where(x => x.Gender == search || search ==null).ToList());

            }

            else

            {

                return View(db.Employees.Where(x => x.Name.StartsWith(search)).ToList());

}

Benefits of Html Helpers in Asp.Net MVC

So today i am going to give an overview on Html helpers in Asp.Net MVC . So first questions that stuck our mind are -

 What are Html helpers ?

 Why to use them instead of using simple Html coded controls

 What are their benefits in Asp.Net MVC

Html helpers are very much similar to Asp.Net web controls . But Html helpers are much more lightweight as compared to Asp.net Web forms Server controls . The similarity between server controls in Asp.net webforms and Html helpers in Asp.Net MVC are Viewstate . Means they both contain the ability to hold or update the data on postbacks using ViewStates for each controls .

Main  Benefits Of using Html Helpers in Asp.net MVC

• MVC Html Helpers contains Overloaded Methods like IPostBackDataHandler that Pre-populate the values of html helpers means it works similar to as viewstates
• Html Helpers is also having one more advantage It provide inbuilt Validation for html helpers textboxes 

Available HTML Helpers 

There following HTML helpers can be used to render (modify and output) HTML form elements:

1. BeginForm()
2. EndForm()
3. TextArea()
4. TextBox()
5. CheckBox()
6. RadioButton()
7. ListBox()
8. DropDownList()
9. Hidden()
10. Password()

Sample Code To Demonstrate Use of Html Helpers

ASPX CODE

<%= Html.ValidationSummary("Create was unsuccessful. Please correct the errors and try again.") %>

<% using (Html.BeginForm()){%>

<p>

<label for="FullName">FullName</label>

<%= Html.TextBox("FullName") %>

<%= Html.ValidationMessage("FullName", "*") %>

</p>

<p>

<label for="Username">Username</label>

<%= Html.TextBox("Username") %>

<%= Html.ValidationMessage("Username", "*") %>

</p>

<p>

<label for="Password">Password:</label>

<%= Html.Password("Password") %>

<%= Html.ValidationMessage("Password", "*") %>

</p>

<p>

<label for="Password">Confirm Password:</label>

<%= Html.Password("ConfirmPassword") %>

<%= Html.ValidationMessage("ConfirmPassword", "*") %>

</p>

<p>

<%= Html.CheckBox("ReceiveNewsletter") %>

<label for="ReceiveNewsletter" style="display:inline">Receive Newsletter?</label>

</p>

<p>

<input type="submit" value="Register" />

</p>

<%}%>

RAZOR CODE

@Html.ValidationSummary("Create was unsuccessful. Please correct the errors and try again.")

@using (Html.BeginForm()){ 

<p>

<label for="FullName">FullName</label>

@Html.TextBox("FullName")  

@Html.ValidationMessage("FullName", "*")  

</p>

<p>

<label for="Username">Username</label>

@Html.TextBox("Username")  

@Html.ValidationMessage("Username", "*")  

</p>

<p>

<label for="Password">Password:</label>

@Html.Password("Password")  

@Html.ValidationMessage("Password", "*")  

</p>

<p>

<label for="Password">Confirm Password:</label>

@Html.Password("ConfirmPassword")  

@Html.ValidationMessage("ConfirmPassword", "*")  

</p>

<p>

@Html.CheckBox("ReceiveNewsletter")  

<label for="ReceiveNewsletter" style="display:inline">Receive Newsletter?</label>

</p>

<p>

<input type="submit" value="Register" />

</p>

} 

Difference Between System.Web and System.WebServer

System.web is the settings section for IIS6 and the built in cassini server (the test server in Visual Studio 2010 and before where you are targeting asp.net 3.5 or lower)

The system.webserver is a child of the configuration section that means in web.config file <system.webserver> tag is placed under
<configuration> Tag.

System.WebServer Tag is contained in web.config file in root directory of website. This file contains configuration that needs to be implemented on IIS for Current project. Configuration coded in <system.webserver> Tag are implemented on IIS and are only applied to Project or Webapplication to which corresponding web.config Belongs. This Tag Can Exist is one of below formats in your project's web.config file in root directory of Web Application.

Empty <system.webserver> Tag Under <configuration> Tag -

<configuration>
  <system.webServer>
  </system.webServer>
</configuration>

The system.web section is used in web.config file of Asp.net WebApplications for defining Server Configuration that are applicable for IIS 6, while the system.webserver version is used to configure IIS 7.0. IIS 7.0 includes a new ASP.NET pipeline and some configuration differences. you can check complete details on link below -

https://msdn.microsoft.com/en-us/library/bb763179.aspx


System.webserver is the Server Configuration section for IIS 7 and above, and the build in IIS Express server which is used in Visual Studio 2010 targeting asp.net 4 and any newer versions that are released in the future.

Sample of Web.config file Contains Both <system.web> and <system.webserver>

Working with Master Pages Asp.net

Why Do We Need Master Pages ?

Most Web sites today have common elements used throughout the entire application or on a majority of the pages within the application. If you look at main page of Reuters News website  ( www.reuters.com ) , you can see common elements that are used throughout the entire web site. Here is screenshot of website given below :-

In this screenshot , notice header section , the navigation section, and footer section on the page. In fact, nearly every page within the entire applicaiton uses these same elements. Even before master pages, you had ways to put these elements into every page through a variety of means; but in most cases, doing so posed difficulties.

Some developers simply copy and paste the code for these common sections to each and every page that requires them. This works , but it's rather labor intensive. However, if you use the copy-paste method, whenever a change is required to one of these common sections of the application, you have to go into each and every page and duplicate the change.

How To Use Master Page In Asp.net

DEMO APP DOWNLOAD LINK IS AVAILABLE  BELOW

1. In Visual Studio click on file then New Project then Choose your preferred
language like i have used c# then choose Web  and Then click on Asp.NET Empty Web Application and click ok

2. Now empty web site solution is created for you

3. Now in solution explorer in right side panel Right click on you solution name

4. In popup menu click on Add then click on New Item

5. Now choose Master Page give it a name like 'master1.Master' and click ok

Each Master Page consist of ContentPlaceHolder  control that control provides the space to other webform that is inheriting this Masterpage to place its own content on that webform along with Content on Master Page The Master Page contents are availaible in Child Webform but we cannot edit these content in child webform But in Content placeholder we can add the content according to our requirements

Content Placeholder are used like below:- 

These lines of code are automatically added to your Master Page .

 <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

<%-- This Place is available to Child web-form to put its content along wit master page --%>

</asp:ContentPlaceHolder>

To place default content within one of the content areas of master page, you simply put it in the contentPlaceholder server control on the master page itself or it is automatically added. Any content page that inherits this master page also inherits the default content

Calling Master Page Content Placeholder in other WebForm

Add  ' MasterPageFile ="~/master1.Master" '   to Page Tag at Top of your Webform

This tells that webform to inherit contents from its master Page and webform can also put its own content within content placeholder avaliable by Master Page

Webform Page code

<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile ="~/master1.Master" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication5.WebForm1" %>

<asp:Content runat ="server" ContentPlaceHolderID ="ContentPlaceHolder1"><p>

Description of code :- In @ Page directive we have included the MasterPageFile that implements the Master Pages concept in your web application or website This highly reduces code in websites and webapplications and it reduces redundancy of code

In this code we have called or used the contentPlaceHolder that we have initialized in Master Page we can add contents to this Content Place Holder that is only specific to this page only.

Nesting Master Pages

Download Demo App  :- How To use Nesting Master Pages In Asp.Net

I hope you see the power that master pages provide to help you create templated web applications . so far you have been creating single master page that the content page can sue. Most companies and organisations, however are not just two layers. Many divisions and groups exist within the organization that might want to use variations of the master by, in effect , having a master page within a master page. With ASP>NET , this is quite possible.

How To USE DEMO APP

In this Demo App i have connected contains :-

( i )  master1.master

( ii ) master2.master  // inherit from master1

( iii) Default.aspx  // has master page - master 2

So we have 2 Master Pages and 1 Webform . These two master pages contain all Designing part of webpage and it remains same for full website so it kept in master . Master1 contains Header and Navigation part and Master 2 conatains other Remaining body part of webpage
