I'm using a RadTreeList with data bound using a DataTable in NeedDataSource.
I set AllowRecursiveSelection to true so that all child nodes are selected too, even if they are not expanded.
Unfortunately, it doesn't work as expected. If I check SelectedItems on the server, I only get a list containing the currently VISIBLE selected items. The child items are not included. If I expand this selected node, the children are selected as expected and appear in the SelectedItems. If I collapse the node again, they don't appear in SelectedItems anymore.
Also, the Items property only contains the currently VISIBLE items, I expected it to contain all items.
The SelectedIndexes property is always correct, but I don't know how I could use this information to find the according data in the DataTable.
What do I have to do to get SelectedItems to return the invisble selected items too?
