Yeah I know the title sounds funny. It is, but like kids they are going to make me crazy.
Ok here is the stiuation. I need to get the transactiontableid datavalue if it is changed (band 2) then the elementid displaytext (band 1?) and the AllocatorID (band 2 child 1?) and then change the value list in RuleName (band 2 child 1 child 1?). The valuelist for RuleName would also be changed for all allocatordetail childs in such manner. I have tried Parent, Selected row and nothing is working. Please help and thank you....

Assuming that the order of the child bands don't change (and thus a row from a different band is returned from the FirstRow property), I don't really see a problem with the code. I don't know why you need to set the ActiveRow, but I don't necessarily see the harm in this either since it may become the active row anyway when the user expands it.

Okay this seems to work. Please review and tell me what you think or if you think I need to make changes. This has been very educational for me. Thank you for your patience though this.
Private Sub dgElements_AfterRowExpanded(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.RowEventArgs) Handles dgElements.AfterRowExpanded
dgElements.ActiveRow = e.Row
Dim i As Integer
Dim itexists As Boolean
If dgElements.ActiveRow.Cells(i).Column.Key = "TransactionTableID" Then
itexists = True
Exit For
Else
itexists = False
End If
Next
If itexists = True Then
ElementID = dgElements.ActiveRow.ParentRow.Cells(0).Value
trantableid = dgElements.ActiveRow.Cells("TransactionTableID").Value ' Since this is what we're checking to see if it changed at the beginning
allocatorid = dgElements.ActiveRow.ChildBands.FirstRow.Cells("AllocatorID").Value
Dim strSQL As String ="sqlstuff"
RulesList.ValueListItems.Clear()
RulesList.ValueListItems.Add(dt.Rows(i).Item("RuleID"), dt.Rows(i).Item("RuleName"))
For i = 0 To dgElements.ActiveRow.ChildBands.FirstRow.ChildBands.Count - 1 'dgElements.ActiveRow.ChildBands(0).Rows(0).ChildBands.Count - 1
Dim ii As Integer
dgElements.ActiveRow.ChildBands.FirstRow.ChildBands(i).Rows(ii).Cells("RuleName").ValueList = RulesList
End Sub
The event args should still give you a handle to the row, so I don't see why you couldn't just replace the row that you got in AfterCellUpdate with this row instead.
Ok now they threw this at me. They want it done when they click the + sign on the row to have it do it for all the valuelists.....can I use the previously written code even though no cell is selected?
Is the only change the use of FirstRow? This method will walk over all of the child bands until it finds a row, so the row you're looking for might not actually be ChildBands(0). Regardless, glad it's working for you.
