As of 3.01, the ExpandedField property of TreeViewBinding no longer exists and we're meant to bind the ExpandedItems property of the tree view instead. However, this is fine for a flat data source but doesn't really work for a hierarchical data source.
I'm loading my hierarchical data source to include all expanded nodes and child nodes so that I can reselect the previously selected node, and this can go down 5 levels or more. So how can I create an expanded items local variable to bind to tree view control from that?
The ExpandedField approach worked fine in this scenario, but I don't see how the ExpandedItems approach can. The only way I can see to resolve is to change my hierarchical data source to be flat which would be a lot of work and wouldn't really be ideal.
On another matter, the class applied to the selected tree node span element seems to have changed from k-state-selected to k-selected, although I don't see this documented anywhere.
Any advice on how I can get round the expanded items problem without drastically rewriting my code would be appreciated.
