Let me first start with...I am teaching myself .net 
Now, having said that...I have a page that contains a 3-level nested gridview:
parent
child
grandchild
For the most part..it works. The parent and child grids both work perfectly. The grandchild however, is causing some issues. I am able to add a record and delete a record from the grandchild grid but I cannot enter edit mode. While stepping through the code, I have determined that the DataBind methods are not actually calling the RowDataBound event. They are not erroring out, not being skipped, just not going anywhere. While stepping through the code, I go to that line, then immediately go to the next line instead of going to the RowDataBound event. I have no idea why! Part of my code is below...if you need more let me know. I appreciate any help you can offer!
I am also declaring the following global variables:
Private gvUniqueID As String = [String].Empty
Private gvNewPageIndex As Integer = 0
Private gvEditIndex As Integer = -1
Private gvSortExpr As String = [String].Empty
Private gvUniqueID1 As String = [String].Empty
Private gvNewPageIndex1 As Integer = 0
Private gvEditIndex1 As Integer = -1
Private gvSortExpr1 As String = [String].Empty
Private RecurringEventRecordNo As Integer = 0
'Public WithEvents gvDirective As UserControl
Dim WithEvents gvDirective As New GridView
Dim WithEvents gvTask As New GridView
Any idea why the code works in the parent and child but not the grandchild gridview? Thanks!
