How to get the selected row or rowindex in a GridView when there's no CommandField?

Asked by cdebel in Programming for ASP.NET, .NET, Microsoft Visual Basic.Net

Here's my problem.  I've a GridView with several buttons in it.  Each button have a CommandName.
I've discovered that when i click on a button in a row, it doesn't select the row and by mather of fact doesn't update the DataKeys.

Is there a way to know on which ROW the button was pressed?  (So this way i could get all the data in other columns of this row).

I thought about adding a column containing "iKey" but make it "invisible" like this:
<asp:BoundField DataField="iKey" Visible="false" />

but in my codebehind when i try to read the value of that invisible cell, it return an empty string.  If i was able to get that key, i could at least do something like this...
for each oRow in gvSubscribedServices.Row
      ' if first column = ikService then
      '     THIS IS MY ROW
      ' endif
next

I'm sure i'm doing things more complicated because there's something i didn't understood yet, so if you have any idea, i would like that.

In the worse case scenario, i'll simply add some code in my ActualSvcCmd sub to connect to the DB, use an SQLDataReader and read all the fields that i need.  It's gonna be slower, and since the data is already loaded in that page, i think there's a way to find that row.

Thanks
