This article will explain your how you can find the control
value present in an itemtemplate of a gridview when user click on button
present in a gridview in asp.net using. In this article I have used asp.net,
gridview, SqlConnection, SqlDataAdapter,
DataTable, Lable Control.
Now in this article first we will create a new asp.net
application and add a gridview control in it. After adding gridview and adding
item template in it your aspx code will look as shown below. In this we have
added a table with label control in which we will display the row record.

Now we will generate the button click event to detect the
row control value in gridview. Here is the code which you have to put on button
click event which is present in gridview itmtemplate.
/// <summary>
/// This function is used for getting control value
/// </summary>
/// <param
name="sender"></param>
/// <param
name="e"></param>
protected
void btnselect_Click(object
sender, EventArgs e)
{
GridViewRow
gvr = ((Button)sender).Parent.Parent as GridViewRow;
Label
lblid = (Label)gvr.FindControl("Label1");
Label
lbltitle = (Label)gvr.FindControl("Label2");
Label
lblpublishyear = (Label)gvr.FindControl("Label3");
Label
lblprice = (Label)gvr.FindControl("Label4");
Label8.Text = lblid.Text;
Label5.Text = lbltitle.Text;
Label6.Text =
lblpublishyear.Text;
Label7.Text = lblprice.Text;
}
|
Now please check the complete code to bind and detect the control
value on button click.
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;
namespace ProjectDemo_Asp.et
{
public partial class Default : System.Web.UI.Page
{
public
string connectionstring = "<-----SQL data base
connection------->";
protected
void Page_Load(object
sender, EventArgs e)
{
if
(!IsPostBack)
{
DataTable
_objdt = new DataTable();
_objdt =
GetDataFromDataBase();
if
(_objdt.Rows.Count > 0)
{
GridView1.DataSource =
_objdt;
GridView1.DataBind();
}
}
}
/// <summary>
/// Function for binding retribing the data from database
/// </summary>
/// <returns></returns>
public
DataTable GetDataFromDataBase()
{
DataTable
_objdt = new DataTable();
string
querystring = "select * from Books;";
SqlConnection
_objcon = new SqlConnection(connectionstring);
SqlDataAdapter
_objda = new SqlDataAdapter(querystring,
_objcon);
_objcon.Open();
_objda.Fill(_objdt);
return
_objdt;
}
/// <summary>
/// This function is used for getting control value
/// </summary>
/// <param
name="sender"></param>
/// <param
name="e"></param>
protected
void btnselect_Click(object
sender, EventArgs e)
{
GridViewRow
gvr = ((Button)sender).Parent.Parent as GridViewRow;
Label
lblid = (Label)gvr.FindControl("Label1");
Label
lbltitle = (Label)gvr.FindControl("Label2");
Label
lblpublishyear = (Label)gvr.FindControl("Label3");
Label
lblprice = (Label)gvr.FindControl("Label4");
Label8.Text = lblid.Text;
Label5.Text = lbltitle.Text;
Label6.Text =
lblpublishyear.Text;
Label7.Text = lblprice.Text;
}
}
}

Now run the application by putting break point on button
click event. Your screen will look as shown below.
Now click on button of a row. Your break point will hit and
your will see that you are able to get the value of the controls which are
present in the itemtemplate of the gridview.
Now pres F5 and check the final output
