Hi Use like this on Row Command Button CommandArgument=   /> And then In code behind protected void grdexam_RowCommand(object sender GridViewCommandEventArgs e) { if (e.CommandName == dtls) { int index = int.Parse(e.CommandArgument.ToString()); Label paperid = (Label)grdexam.Rows[index].FindControl(Label1); Label subject = (Label)grdexam.Rows[index].FindControl(testname); SqlCommand cmd = new SqlCommand(select * from ExamMaster where groupid=' + Session[grpid] + ' and papercode=' + paperid.Text + ' con); SqlDataAdapter adp = new SqlDataAdapter(cmd); DataTable dt = new DataTable(); adp.Fill(dt); if (dt.Rows.Count > 0) { GridView1.DataSource = dt; GridView1.DataBind(); pnlsubbjectiv.Visible = true; } else { Response.Write(wromg); } } }

Hi Try something like this. protected void gridMembersList_RowCommand(object sender GridViewCommandEventArgs e) { if (e.CommandName == Add) // Or something { int index = Convert.ToInt32(e.CommandArgument.ToString()); Literal ltrlslno = (Literal)gridMembersList.Rows[index].FindControl(ltrlSlno); Literal ltrlName = (Literal)gridMembersList.Rows[index].FindControl(ltrlName); Session[ltrlName ] = ltrlName.Text; } }
