Datagridview issue with CurrentRow.Index not having been established

I have this piece of code included on a tabpage that I originally had set with .SelectionChanged, but it would error when the rowheader was clicked.  My issue is that the CurrentRow.Index is not set when I click outside an actual row.  The code below, I realize now with RowEnter,  has not initialized CurrentRow.Index.

What can I modify about this code where if a row becomes active in any certain way (clicked, coded, etc.) and also if headers are clicked that I can handle CurrentRow.Index.  Do I just need to create an error handler with some 'ignore' code.  I'm skeptical about that because of my 'PopulateParticipants' Sub where data is drawn from a dataview.

Thanks in advance!

Private Sub grdviewParticipants_RowChg(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles grdviewParticipants.RowEnter

        If Activating Then Exit Sub

        Activating = True

        If dvParticipants.Count > 0 Then

            If grdviewParticipants.CurrentRow.Index >= 0 Then

                grdviewParticipants.CurrentCell = grdviewParticipants.Item(3, grdviewParticipants.CurrentRow.Index)

                glCurrentParticipantRow = grdviewParticipants.CurrentRow.Index

                glParticipant = dvParticipants(grdviewParticipants.CurrentRow.Index)("participant_id").ToString

                PopulateParticipants()

            End If

        End If

        Activating = False

    End Sub

Did you try looking at e.RowIndex?

Can't see the forest for the trees.

Got complacent.  This actually reduces the need for a grdview.MouseClick that I have on multiple gridviews in order to populate fields.  Instead of using CurrentRow.Index AT ALL.....use of e.RowIndex takes care of all the problems I had or may have in the future I think with populating fields from accessing the grid.

Thanks much again!
