How to expand table header row in code? (Read 3484 times)

	I have a diagram with quite a few tables that each have a Header row then a bunch of table rows; I initially draw it with the tables collapsed, but then I want to expand the table header in code -- I thought I could do this: Code Dim tn As TableNode = CType(node, TableNode) For Each row As TableNode.Row In tn.Rows If row.Header AndAlso (Not row.Expanded) Then row.Expanded = True End If Next But nothing seems to happen, -- i checked in the debugger that the row.Expanded line is being hit, but in the GUI, the tables stay with their rows unexpanded. Can someone help?

	Update: I notice that my table headers that are affected actually have the - indicator, not the + indicator, seeming to indicate they are expanded -- also, if you click the - it does nothing, but goes + then if you click the + it expands -- so there seems to be a disconnect -- part of the code thinks the rows are expanded, but they don't actually expand

	Are you sure the table has any rows that are not marked as headers?

	Yes -- in order to get drawn in the first place, each Table must have at least one non-header row -- and when you -+- click, this is confirmed.

	Could you save to xml and email us the diagram as it looks before running that code?

	Ahh... I discovered what is happening... The code-based expansion does not cause the TableNode_SectionExpanded event to trigger, and that event is where I actually resize the TableNode -- so I had to add code to resize the node when I was expanding it in code. But... it does seem that this is a bug -- I would have expected the SectionExpanded event to trigger regardless whether caused by the user or code...

	The control raises events mostly for users actions. I suppose our developers thought you wouldn't need notifications for actions that you cause yourself from code, so you get notifications only for what's done interactively. There are some exceptions though, e.g. the ValidateAnchorPoint event.
