Hi,
I'm using Essential Studio 6.3.0.30 with VS2008.
To display the GridGroupingControl my users have to follow a preview workflow : a preview search for example. We can describe it like that :
1) use a textbox as a search field
2) click on the search button
3) the GridGroupingControl appears
4) click on a parent row to display a child table
5) double-click on a child rows to get in the edit form
6) click on an other row to get out the edit form
7) make an other search (start again at 1))
My problem is that if a user make a second search without getting out the edit form (5) --> 7) without 6)), when I want to display the GridGroupingControl, I've got an error :

----------------------------------------------
I've tried to put this in my search button event handler :
----------------------------------------------
If Not (GGC_Design.Table.CurrentRecord Is Nothing) Then
GGC_Design.Table.CurrentRecord.EndEdit()
End If
----------------------------------------------
and this :
----------------------------------------------
GGC_Design.Table.CurrentRecordManager.EndEdit()
----------------------------------------------
But it doesn't work. I've tried to do this too :
----------------------------------------------
Protected Sub GGC_Design_CurrentRecordContextChange(ByVal sender As System.Object, ByVal e As CurrentRecordContextChangeEventArgs) Handles GGC_Design.CurrentRecordContextChange
If Not (e.Action = CurrentRecordAction.BeginEditCalled And e.Action = CurrentRecordAction.BeginEditComplete) Then
If Not (GGC_Design.Table.CurrentRecord Is Nothing) Then
GGC_Design.Table.CurrentRecord.EndEdit()
End If
GGC_Design.Table.CurrentRecordManager.EndEdit()
End If
End Sub
----------------------------------------------
It doesn't work either. In the both case, the GGC_Design.Table.CurrentRecord is always nothing.
Any idea ?
Thanks a lot.
