These events do not seem to be firing in the latest beta version. Here is how I am adding the node and also the definition of the events in .aspx.vb:

Private Sub AddTableNode()
       Dim oNode As DiagramNode
       oNode = diagView.Diagram.Factory.CreateTableNode(0, 0, 35, 20)

       Dim otablenode As TableNode = oNode
       otablenode.ColumnCount = 2
       otablenode.RowCount = 2
       otablenode.CaptionHeight = 10
       otablenode.Rows(0).Header = True
       otablenode.Rows(0).Expanded = True
       otablenode.Item(0, 0).ColumnSpan = 2

       otablenode.OffsetHeaderRows = True
       otablenode.Item(0, 0).Text = "Header Row"
       otablenode.Item(0, 1).Text = "sadfsadfsadfsadf"
       otablenode.Item(1, 1).Text = "4sadfsadfsadfdsaf"
    End Sub


Public Sub Diagram_TableSectionExpanded(ByVal sender As Object, ByVal e As MindFusion.Diagramming.RowEventArgs) Handles diagView.diagram.TableSectionExpanded
    End Sub
    Public Sub Diagram_TableSectionCollapsed(ByVal sender As Object, ByVal e As MindFusion.Diagramming.RowEventArgs) Handles diagView.diagram.TableSectionCollapsed
    End Sub



Thanks.

It is not needed immediately by our software since we are really just prototyping at this point,but at some point it may be needed. I think it would be a great feature to add in the future though. I also noticed moving the table node around on the diagram is a little weird in comparison to a shape node. It seemed really hard to get the move icon to show up over the table to move. Everything else seems to be working great. As always, thanks for the quick response.
