how to get textBox in GridView when click on edit button using Hovermenu and Get RowIndex..?

Hi i m using GridView with hovermenu and i want t开发者_开发技巧hat when we click on edit button then we get TextBox to write in Gridview and also i get error when click on edit for e.commandArgument is null so please give me code for this both

Give your edit button command name like this,

<asp:LinkButton ID="LinkEdit" runat="server" 
  CausesValidation="false"  CommandName="EditRow" Text="Edit"></asp:LinkButton>

and in RowCommand event of ur gridview

if (e.CommandName == "EditRow")
{
   TextBox tbx =  (TextBox)gridCategory.Rows[Convert.ToInt32(e.CommandArgument)].FindControl("UrTxtID");
}

Any how its really difficult to tell what you are doing wrong without seeing your code..

EDIT:

i think you need to set CommandArgument='<%# Container.DataItemIndex %>' in your edit button...

I ran across your post while searching for a way to get the current row in a gridview rowcommand event.
I also ran across this link and thought I'd share: http://ranafaisal.wordpress.com/2008/03/31/how-to-get-the-current-row-in-gridview-row-command-event/

This solved my problem and seems very clean.
