GridView DataBound - values not set when EdiIndex <> -1

With the VB below behind a GridView when I step through the code in debug, as I select Edit mode, DataBound fires and iReqID becomes the correct value of the DataKey and iModifiedBy becomes the correct value of iUserName.

When I click "Save", the DataBound fires again and iReqID is 0 and iModifiedBy is "" because it's no longer in Edit mode and the values are not set and SendModifiedByToRequisition doesn't get called.  Crap, this is like a catch 22.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound
    If GridView1.EditIndex <> -1 Then
        Dim iReqID As Integer = CType(GridView1.DataKeys(GridView1.EditIndex).Value, Integer)        'CInt(GridView1.DataKeys(GridView1.EditIndex).Value)
        Dim iModifiedBy As String = iUserName
        Call SendModifiedByToRequisition(iModifiedBy, iReqID)
    End If
End Sub

I think you're probably using the wrong events for whatever it is you are trying to achieve. You should probably be looking at the RowEditing and RowUpdating/RowUpdated events instead.

Hi again, Carl.  Yes, I was thinking the same thing.  My experience level is not very high so I'm not sure what event to use when.

Basically it's like this:

     Editing - Fired when the gird enters edit mode
     Updating - Fires when switching back to Read mode, but before data is committed
     Updated - Fires when switching back to Read mode and after data is committed

Updating fires prior to Updated.

It looks like RowUpdated is where I want to put it.

Yep.  RowUpdated seems to be working fine.  Thank you again, Carl.
