In above code I have use BoundField for bind the user
detail.
Now check the code to bind and change the header text on
button click.
using System;
using System.Data.SqlClient;
using System.Data;
using System.Web.UI.WebControls;
namespace WebApplication1
{
public partial class WebForm1 : System.Web.UI.Page
{
protected
void Page_Load(object
sender, EventArgs e)
{
if
(!IsPostBack)
{
BindGridView();
}
}
private
void BindGridView()
{
SqlConnection
con = new SqlConnection(System.Configuration.ConfigurationManager.
ConnectionStrings["con"].ToString());
try
{
DataTable
objdt = new DataTable();
string
query = "select * from UserDetail;";
SqlDataAdapter
da = new SqlDataAdapter(query,
con);
con.Open();
da.Fill(objdt);
con.Close();
if
(objdt.Rows.Count > 0)
{
GridView1.DataSource =
objdt;
GridView1.DataBind();
}
}
catch
{
con.Close();
}
}
protected
void Button1_Click(object
sender, EventArgs e)
{
GridView1.HeaderRow.Cells[0].Text
= "Student Name";
}
}
}
|
On above code I have used a function to bind the data. Now I
have I have added the GridView1.HeaderRow.Cells[0].Text
= "Student Name"; to change the header text.
Now we have done run the application to check the output.
