Hello,
I have a RadTreeView which I need to display inside a combobox and also to be able to sort/filter through it. I can't seem to make it work using your examples from here
http://www.telerik.com/blogs/treeview-in-a-combobox-dropdown-using-radcontrols-for-silverlight and here
http://www.telerik.com/blogs/treeview-in-combobox-take-3-silverlight-3-wpf-and-radcontrols . (they don't seem to work/compile either)
What I did manage was to partly replicate the behaviour I wanted using your Rad​DropDownButton tutorial provided here: http://www.telerik.com/blogs/treeview-in-combobox-with-radcontrols-for-silverlight-or-wpf-final-take
Problem is I really need it to be sortable the way ComboBox is. Can you show me an updated example I can use to make this work?

By default RadComboBox is not designed to display data in hierarchical manner. Thus placing RadTreeView inside editable RadComboBox might cause the desired by you filtering behavior and functionality not to work as expected - the control does not have implemented logic for filtering hierarchical data.
However, what we could suggest you is to use RadAutoCompleteBox instead. With some modifications like custom FilteringBehavior and custom highlight of the matching items the desired behavior and functionality could be achieved. We have created a sample project that demonstrates that - please, check it.
Hopes this helps.
