{
     //code
}

when I click in the grid view on the开发者_Python百科 lable control then I want to get the Rowindex.Please help.

The OnCommand for your linkbutton would be something like this

protected void lnk_Command(object sender, CommandEventArgs e)
{
   // The Namingcontainer would be Gridrow
   // You can get the rowindex in this fashion
    ((sender as LinkButton).NamingContainer as GridViewRow).RowIndex    
}

it will return your current row. you don't need to row index..

if(e.CommandName == "")
{
GridViewRow row = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
}

For LinkButton:

CommandArgument='<%#((GridViewRow)Container).RowIndex%>'

in .cs:

protected void gv_CommDetails_RowCommand(object sender, GridViewCommandEventArgs e)
        {

            try
            {
                int index = Convert.ToInt32(e.CommandArgument); //Here you can get the index.

                if (e.CommandName == "ViewSummary")
                {
                   drp_Comm.Items.FindByValue(((HiddenField)gv_CommDetails.Rows[index].Cells[0].FindControl("hdn_CommCode")).Value).Selected = true;
                   txt_CommDescription.Text =gv_CommDetails.Rows[index].Cells[2].Text;
                }

            }

            catch (Exception ee)
            {
                string message = ee.Message;
            }

        }
