Expanding

Hi, I have a grouping grid that has 5 to 6 levels and it''s databound. I have a column called DoExpand with the values 1 or 0. I''d like the grid on load to expand only the groupings with DoExpand = 1. Also, if the child''s DoExpand = 1 but the parent not, will the grid expand the parent so it can expand the child? thanks.

Hi Bernard, I am not not sure I fully understand the questions, but here is a try: You can loop through all the records in the grid and call ShowRecord(). This will make sure the record will be visible and all parent groups are expanded: foreach(Record r in this.gridGroupingControl1.Table.Records) { string s = r.GetValue("DoExpand").ToString(); if(s == "1")) this.gridGroupingControl1.Table.ShowRecord(r); } If this is not what you need can you post a sample project that shows what you need? I could then modify it to get it working. Thanks, Stefan

hi, i tried your code, and nothing happens. i needed to put true/false as the last item in the signature. .Table.ShowRecord(r, True) The grid records are still colapsed.

Here is a sample that expands all nodes where [Name] Like ''1''. You have to recursively check records, and then expand things (records and childtables) as you back out of the recursion if you have found what you are looking for. http://64.78.18.34/forums/Uploads/nestedtables.zip

Here is the sample in VB. http://64.78.18.34/forums/Uploads/nestedtables_vb.zip

Hi, I had a look at your sample, but i don''t have any nested tables. It''s just the 1 table with multiple groupings. I changed the code to this, but it still wont expand. Dim isExpanded As Boolean = False Dim r As Record For Each r In MarketingDG.Table.Records Dim o As Object = r.GetValue("DoExpand") If Not o Is Nothing AndAlso o.ToString = "1" Then r.SetExpanded(True, True, False) r.InvalidateSummariesBottomUp() End If Next MarketingDG.Table.InvalidateSummariesBottomUp() MarketingDG.TableControl.Refresh() ---- = ---- Are there any properties that does not allow the grid to programatically expand?

Here is code that opens groups where Col3="1".
Private Sub button2_Click(sender As Object, e As System.EventArgs)
   Dim r As Record
   For Each r In  Me.gridGroupingControl2.Table.Records
      If r.GetValue("Col3").ToString() = "1" Then
         Dim el As Element = r
         While Not (el.ParentGroup Is Nothing)
            el.ParentGroup.IsExpanded = True
            el = el.ParentGroup
         End While
         Console.WriteLine(r.ToString())
      End If
   Next r
   Me.gridGroupingControl1.Table.InvalidateSummariesBottomUp()
   Me.gridGroupingControl1.TableControl.Refresh()
End Sub ''button2_Click
