Radio Button Selection and Change Selected Row Style of GridView Using jQuery

In this article I will explain how to make a single radio button selection in a GridView using JQuery and how to change a selected row style of a GridView with a radio button using jQuery.

Introduction

In this article I will explain how to make a single radio button selection in a GridView using jQuery and how to change a selected row style of a GridView with a radio button using jQuery.

Description

In this article:

  • First I was create a database in the SQL Server 2008.
  • Create an ASP.NET website and add a GridView control with Radio Button to the page.
  • I am binding the GridView with a DataTable object that I created in the Page Load event in the code behind file.
  • Next you need to add following CSS style rules inside the <head> section of the page. We will use the headerRow, GridView and selectedRow CSS classes.
  • Next add the jQuery script file reference inside the <head> section of the page depending on the script file location and jQuery version you are using.
  • Next add the following jQuery code inside a script block in the <head> section of the page.

Now time to see the details of all that.

First go through SQL Server and make a table. The following snapshot shows the process.

Step 1: First we have to create a Web Application.

  • Go to Visual Studio 2010.
  • New--> And select the Web Application.
  • Give whatever name you want to.
  • Click OK.

Step 2: Secondly you have to add a new page to the website.

  • Go to the Solution Explorer.
  • Right-click on the project name.
  • Select add new item.
  • Add new web page and give it a name.
  • Click OK.

Step 3: In this step we will see how to add style sheet code. Whenever we write style sheet code you have to be careful that it is written inside the <style></style> tags and you have to place it inside the head section. We will use the headerRow, GridView and selectedRow CSS classes.

<style type="text/css">
        .Gridview
        {
            font-family: Verdana;
            font-size: 11px;
            font-family: Arial;
            text-decoration: none;
            color: #5a5a5a;
            height: 20px;
            padding-left: 10px;
            border: solid 1px #d7d8f0;
            width: 300px;
        }
        .SelectedRowStyle
        {
            background-color: #ffeb95;
            font-size: 11px;
            font-family: Arial;
            text-decoration: none;
            color: #5a5a5a;
            height: 20px;
            padding-left: 10px;
            border: solid 1px #d7d8f0;
        }
        .headerRow
        {
            background-color: #458B74;
            color: White;
            font-weight: bold;
        }
</
style
>

 Step 4: In this step we have to write the script reference to the aspx page; let us see from where you have to write the script code.

Step 5: Let us see the script code which you have to add inside the <script></script> tags and that will be placed either in the head section or the body section as you prefer.

<script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>

Step 6: In this step we have to write the jQuery code which is given below.

<script language="javascript" type="text/javascript">
        function SelectSingleRadiobutton(rdBtnID) {
            //process the radio button Being checked.
            var rduser = $(document.getElementById(rdBtnID));
            rduser.closest('TR').addClass('SelectedRowStyle');
            rduser.checked = true;
            // process all other radio buttons (excluding the the radio button Being checked).
            var list = rduser.closest('table').find("INPUT[type='radio']").not(rduser);
            list.attr('checked', false);
            list.closest('TR').removeClass('SelectedRowStyle');
        }
</
script
>

Step 7: In this step you will see the body code of the Default2.aspx page which is given below.

Body Code:

<body>
    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" CssClass="Gridview" AutoGenerateColumns="false"
            DataKeyNames="id" HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:RadioButton ID="rdbUser" runat="server" OnClick="javascript:SelectSingleRadiobutton(this.id)" />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="id" HeaderText="Id" />
                <asp:BoundField DataField="name" HeaderText="Name" />
                <asp:BoundField DataField="salary" HeaderText="Salary" />
                <asp:BoundField DataField="addres" HeaderText="Address" />
            </Columns>
        </asp:GridView>
        <br />
        <br />
        <br />
        <br />
        <br />
        <br />
    </div>
    </form
>
</body>

Step 8: In this step we will see the complete code of the Default2.aspx page which is given below.

Code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<
title> GriedView Animation Using jQuery in ASP.NET</title
>
<script type="text/javascript" src="Scripts/jquery-1.4.1.min.js"></script>
<script language="javascript" type="text/javascript">
        function SelectSingleRadiobutton(rdBtnID) {
            //process the radio button Being checked.
            var rduser = $(document.getElementById(rdBtnID));
            rduser.closest('TR').addClass('SelectedRowStyle');
            rduser.checked = true;
            // process all other radio buttons (excluding the the radio button Being checked).
            var list = rduser.closest('table').find("INPUT[type='radio']").not(rduser);
            list.attr('checked', false);
            list.closest('TR').removeClass('SelectedRowStyle');
        }
</
script
>
<style type="text/css">
        .Gridview
        {
            font-family: Verdana;
            font-size: 11px;
            font-family: Arial;
            text-decoration: none;
            color: #5a5a5a;
            height: 20px;
            padding-left: 10px;
            border: solid 1px #d7d8f0;
            width: 300px;
        }
        .SelectedRowStyle
        {
            background-color: #ffeb95;
            font-size: 11px;
            font-family: Arial;
            text-decoration: none;
            color: #5a5a5a;
            height: 20px;
            padding-left: 10px;
            border: solid 1px #d7d8f0;
        }
        .headerRow
        {
            background-color: #458B74;
            color: White;
            font-weight: bold;
        }
</
style
>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:GridView ID="GridView1" runat="server" CssClass="Gridview" AutoGenerateColumns="false"
            DataKeyNames="id" HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:RadioButton ID="rdbUser" runat="server" OnClick="javascript:SelectSingleRadiobutton(this.id)" />
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:BoundField DataField="id" HeaderText="Id" />
                <asp:BoundField DataField="name" HeaderText="Name" />
                <asp:BoundField DataField="salary" HeaderText="Salary" />
                <asp:BoundField DataField="addres" HeaderText="Address" />
            </Columns>
        </asp:GridView>
        <br />
        <br />
        <br />
        <br />
        <br />
        <br />
    </div>
    </form
>
</body>
</html>

Step 9: In this step we will see the design of the Default2.aspx page which is given below.

Step 10: In this step I am binding the GridView with a DataTable object that I created in the Page Load event in the code behind file of the Default2.aspx page.

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.SqlClient;
public partial class Default2 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        SqlConnection con = new SqlConnection(@"Data Source=.;Initial Catalog=akshay;Persist Security Info=True;User ID=sa;Password=wintellect";
        SqlDataAdapter adap = new SqlDataAdapter("select * from Person",con);
        DataSet ds=new DataSet();
        adap.Fill(ds,"Person");
        GridView1.DataSource = ds.Tables["Person"];
        GridView1.DataBind();
        GridView1.UseAccessibleHeader = true;
        GridView1.HeaderRow.TableSection = TableRowSection.TableHeader;
    }
}

Step 11: In this step we are going to run the Default2.aspx page by pressing F5.
