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?
ok sorry I missed your post. I moved it to this event and it bails if it is not that cell which is good. Now I bet I have to change that code.
I'm not sure why you're dealing with selected rows here, it seems like it would make the logic more complex, especially if you later actually do need to deal with selection. You can get the row from e.Cell in the AfterCellUpdate (or CellChange) events, at which point you should be able to traverse up the parent hierarchy (via the row.ParentRow) property, or down through the children (via row.ChildBands[key/index].Rows).
your totally right. I have got the values corrected now thanks to you. Now just trying to put the new values in the valuelist. So far like this.....
Dim oClm As UltraGridColumn
For Each oBand In dgElements.DisplayLayout.Bands
oBand.Columns("RuleName").ValueList = RulesList
Case Else
End Select
Next
Ok to change that value list for RuleName in all the rows of the allocator children this is what i have but nothing is happening:
Dim oBand As UltraGridBand
Dim oEditor As Infragistics.Win.EditorWithCombo
'dgElements.ActiveRow.ChildBands(0).Rows(0).Cells("AllocatorID").Value
Dim ii As Integer
dgElements.ActiveRow.ChildBands(0).Rows(0).ChildBands(i).Rows(ii).Cells("RuleName").ValueList = RulesList
It appears to have worked. I had a stoppoint in there i had forgot to take out. Thank you for your help.
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
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
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.
