Hi Hrishikesh Mehta,
I am sorry for the delayed reply.
Indeed the selected container may not always be available when the selection is changed. Sometimes it may not be available at all if it has not been generated yet.
Normally if it is available, it will be found. You access in a dispatcher like so:
sender, Telerik.Windows.Controls.SelectionChangedEventArgs e)
var container = treeList.SelectedContainer;
This means that the code in the dispatcher will eb executed a little bit later when the container will be available.
Please note that the TreeListView is a CTP and major changes are expected in the next version when we will base the control on the GridView rather than the TreeView. It is best not to base any production code on it yet.
