Sorry not on validating but on cellvaluechanged...

This the code i wrote 

    Private Sub GridDetail_CellValueChanged(sender As Object, e As GridViewCellEventArgs) Handles GridDetail.CellValueChanged
        If e.Column.Name = "Kode" Then
            MsgBox(e.Row.Cells(0).Value.ToString & ", " & e.RowIndex & ", " & e.ColumnIndex)
        End If
    End Sub

for the first time it get -1, 0. How to get the real position ? i mean 0,0 for rowindex and columnindex

 

Thanks
