I have a question, how do I pass my button's command argument to the row updating event of asp.net gridview?

I have this code:

<asp:Button ID="btnEdit" runat="server" CommandName="Edit" Text="Edit" CommandArgument='<%# Eval("id") %>' />

I have used this with my delete button and its working fine,

int Deleteid = int.Parse((sender as ImageButton).CommandArgument);

I placed the code inside the ON CLICK EVENT OF MY BUTTON.

my question is, how do I fire this command argument. my edit button inside ROW UPDATING
since I need to update only the ROW which has the "id" just like what I did in my delete event, help please!
