Hello,
we are using a RadTreeView with Columns and we see a very strange behaviour.
Some of the items of the tree view are initially expande by setting IsExpanded to true in their Constructor (we use a TreeViewModel). When a values of the properties binded to the treeView changes, it works fine for all items, except for the ones that were initially expanded. No data update is performed. It seems as if the bindings were lost.
If we remove the IsExpanded in the constructor, the binding seems to be ok, but we need to expand some of the items initially.
What can we do?
Best regards,
Jerma
