In above code I have use itemtemplate to bind the gridview
fields and used label control to display the value using Eval.
Now check the code to bind and display no of pages.
using System;
using System.Data.SqlClient;
using System.Data;
using System.Web.UI.WebControls;
using System.Collections;
namespace WebApplication1
{
public partial class WebForm1 : System.Web.UI.Page
{
protected
void Page_Load(object
sender, EventArgs e)
{
if
(!IsPostBack)
{
GetDistinctValue();
}
}
private
void GetDistinctValue()
{
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)
{
string
SelectedName = "";
foreach
(GridViewRow item in
GridView1.Rows)
{
CheckBox
checkbox1 = (CheckBox)item.FindControl("CheckBox1");
if
(checkbox1.Checked == true)
{
Label
lblName = (Label)item.FindControl("lblName");
Label
lblNamAddress = (Label)item.FindControl("lblNamAddress");
Label
lblUserType = (Label)item.FindControl("lblUserType");
SelectedName = "Name : "+ lblName.Text + "";
SelectedName =
SelectedName + "Address : " +
lblNamAddress.Text + "";
SelectedName =
SelectedName + "Type : " +
lblUserType.Text + "";
}
}
lblSelectedRowValue.Text =
SelectedName;
}
}
}

On above code I have used a function to bind the data. Now I
have I have added the. Now check the below code to display the selected row of
gridview control. I have displayed the selected row value on a label control.
string
SelectedName = "";
foreach
(GridViewRow item in
GridView1.Rows)
{
CheckBox
checkbox1 = (CheckBox)item.FindControl("CheckBox1");
if
(checkbox1.Checked == true)
{
Label
lblName = (Label)item.FindControl("lblName");
Label
lblNamAddress = (Label)item.FindControl("lblNamAddress");
Label
lblUserType = (Label)item.FindControl("lblUserType");
SelectedName = "Name : "+ lblName.Text + "";
SelectedName =
SelectedName + "Address : " +
lblNamAddress.Text + "";
SelectedName =
SelectedName + "Type : " +
lblUserType.Text + "";
}
}
lblSelectedRowValue.Text =
SelectedName;
|
Now we have done run the application to check the output.
