Highlight GridView Row selected in asp.net

Advertisement


In this article I will explain highlight gridView row selected in asp.net
I am creating a database table in Sql server
USE [chinnu]
GO

/****** Object: Table [dbo].[EmployeeInfo] Script Date: 10/31/2013 22:39:45 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[EmployeeInfo](
[EmpId] [nvarchar](50) NOT NULL,
[EmpName] [nvarchar](50) NOT NULL,
[EmpAddress] [nvarchar](50) NOT NULL,
[EmpDesignation] [nvarchar](50) NOT NULL
) ON [PRIMARY]

GO

I created a empty solution with name GridMouseOver.

Now I am creating a webform with name MouseOver.aspx.

I am designing the UI.
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="MouseOver.aspx.cs" Inherits="GridMouseOver.MouseOver" %>

<!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></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gridview" runat="server" AutoGenerateColumns="False" OnRowCreated = "gridviewrowchanged" >
<Columns>
<asp:BoundField DataField="EmpId" HeaderText="EmployeeId" InsertVisible="False"
/>
<asp:BoundField DataField="EmpName" HeaderText="EmployeeName" InsertVisible="False"
/>
<asp:BoundField DataField="EmpAddress" HeaderText="EmployeeAddress" />
<asp:BoundField DataField="EmpDesignation" HeaderText="EmployeeDesignation" />
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>

Now I am writing the logic in aspx.cs page as shown below

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.Configuration;

namespace GridMouseOver
{
public partial class MouseOver : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
BindGridData();

}
}
private void BindGridData()
{
try
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Connstring"].ConnectionString))
{
SqlCommand command = new SqlCommand("SELECT * from EmployeeInfo", con);
SqlDataAdapter da = new SqlDataAdapter(command);
DataTable dt = new DataTable();
da.Fill(dt);
gridview.DataSource = dt;
gridview.DataBind();
}
}
catch (Exception ex)
{
}

}

protected void gridviewrowchanged(object sender, GridViewRowEventArgs e)
{
e.Row.Attributes.Add("onmouseover","this.style.background = 'Yellow'");
e.Row.Attributes.Add("onmouseout", "this.style.background = 'White'");
}
}
}

Now I am adding the web.config connection string

<connectionStrings>
<add name="Connstring" connectionString="Data Source=DotNetSharePoint;Database=Chinnu;User Id=sa;Password=password123;" providerName="System.Data.SqlClient" />
</connectionStrings>


finally Press F5,we can the out as looks like
