Hi Tanuj,

You should do like this:

protected void ImageButton_enable_Click(object sender,ImageClickEventArgs e)
{
   
foreach(GridViewRow gvrow in GridView_enable.Rows)
    {
        CheckBox chk1=gvrow.FindControl("CheckBoselect") as CheckBox;
        if (chk1 !=null && chk1.Checked == true)
        {
            Label lblEmail = gvrow.FindControl("Label1") as Label;
            if(lblEmail != null)
                
Console.WriteLine(lblEmail.Text);
        }
     }
}
