If your GridView is databond  make an index column in the resultset you retrive like this   select row number   over order by YourIdentityColumn asc -1 as RowIndex    from YourTable where  Expresion    In the command control you want to use make the value of CommandArgument property equal to the row index of the DataSet table RowIndex like this    lt asp LinkButton ID  lbnMsgSubj  runat  server  Text   lt    Eval  MsgSubj     gt   Font-Underline  false  CommandArgument   lt   Eval  RowIndex     gt     gt    Use the OnRowCommand event to fire on clicking the link button like this    lt asp GridView ID  gvwStuMsgBoard  runat  server  AutoGenerateColumns  false  GridLines  Horizontal  BorderColor  Transparent  Width  100   OnRowCommand  gvwStuMsgBoard RowCommand  gt    Finally the code behind you can then do whatever you like when the event is triggered like this   protected void gvwStuMsgBoard RowCommand object sender  GridViewCommandEventArgs e        Panel pnlMsgBody    Panel gvwStuMsgBoard Rows Convert ToInt32 e CommandArgument   FindControl  pnlMsgBody        if pnlMsgBody Visible    false                pnlMsgBody Visible   true            else               pnlMsgBody Visible   false
