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....

If you're trying to do this in something like CellChange or AfterCellUpdate, then you should have a reference to the TransactionTableID cell. You can get this value, then look at the ParentRow.ChildBands[ElementDetailKey].Rows[0] for the ElementID (you might wan to look at the Text property of the cell). To get the AllocatorID, it looks like it's just the first child row, so you'd have row.ChildBands[0].Rows[0].Cells["AllocatorID"]. Similarly to get at the RuleName, you'd look at the child row in the same way off of the AllocatorDetail row.
Were there additional parts of this that were giving you trouble? I'm not sure that I fully understood when you are trying to do this and which problems you were facing.

Ok lets start iwth that. How can I capture the datavalue of the transacitontableId once it is changed? Wouldn't the cell update event fire for everything if I do that?
Is there more than one child band? I'm not really sure what could be causing the issue at this point, especially if it's working for the first Allocator row and not any subsequent rows.
As a side note, it would be more efficient to use the GetCellValue method on the row instead of the Cells(...).Value, since the latter will cause the Cell objects to be created if they haven't been already. This is a moot point if you've already rendered all the cells, but couldn't hurt to code it in this fashion.
the one marked "ME Orders Volume" in Allocations is the one failing. Are we talking about the same thing here?
I have no idea why but this appears to work.
Private Sub dgElements_AfterCellUpdate(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.CellEventArgs) Handles dgElements.AfterCellUpdate
If e.Cell.Column.Key <> "TransactionTableID" Then
Exit Sub
End If
ElementID = e.Cell.Row.ParentRow.Cells(0).Value
trantableid = e.Cell.Value ' Since this is what we're checking to see if it changed at the beginning
allocatorid = e.Cell.Row.ChildBands.FirstRow.Cells("AllocatorID").Value()
'allocatorid = e.Cell.Row.ChildBands(0).Rows(0).Cells("AllocatorID").Value

Dim oDa As New SqlDataAdapter(strSQL, oConn)
oDa.Fill(dt)
RulesList.ValueListItems.Clear()
Dim i As Integer
RulesList.ValueListItems.Add(dt.Rows(i).Item("RuleID"), dt.Rows(i).Item("RuleName"))
Next
For i = 0 To e.Cell.Row.ChildBands.FirstRow.ChildBands.Count - 1 'dgElements.ActiveRow.ChildBands(0).Rows(0).ChildBands.Count - 1
Dim ii As Integer
e.Cell.Row.ChildBands.FirstRow.ChildBands(i).Rows(ii).Cells("RuleName").ValueList = RulesList
End Sub
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?
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.
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.
