I'm not sure if this is the right place for this question,
but I didn't find anywhere more suitable ...
In beta 1 the AdvancedDataGrid had an openItems attribute
that one could reset after a change to keep the tree in the same
state. Now that attribute is gone and I don't see any other way to
accomplish the same effect.
My use case is that I have an XML document as a hierarchical
data source. I add nodes to it at run-time and need to refresh the
ADG so that the new nodes show up. However on resetting the
datasource the tree closes.
Since the datasource is really the same one (just with new
data) I was previously able to use openItems to reset the tree to
the "open" state it was in before.
Is there a better method for doing this? Or some way to get
the tree to recognize new data without closing?
