I am using RadTreeView control which is binded to object collection, however when collection changes the new display always appears in collapsed mode by default is there any way that I can get expanded display by default.
If you are using ViewModels, you can bind the IsExpanded property of the RadTreeViewItem to a boolean property in your ViewModel using ContainerBindings. Please refer to this help article and to the attached project to see a basic implementation. Let us know if this helped you or not.
