Is there a way to Expand all Nodes of a "LoadOnDemand" RadTreeList with a Button-Click or similar event?
If I use the ExpandAllItems it simply takes away the (+) Signs (i.e. it tries to expand but does not call the ChildItemsDataBind-Method).
Any Ideas?
Our customer most often only needs to view some path of the tree, which would load on demand more applicable, but sometimes want's to view all nodes or use the ExcelExport Function to Export the whole tree.

Hi Pascal,
Note that required functionality is not supported with the RadTreeList control and it is actually not applicable in this case. In case you need to expand all items at the same time it will be better to use the basic loading mechanism instead of LoadOnDemand
