we are using 2 RadTreeview in of our form in WPF application.

we got a requirement that one RadTreeView will have  only one parent folder like Favoirites.

so whenever any folder is selected by user in another RadTreeview ,then that folder must be added in Favoirites

 

Ex:

RadTreeView1

 Favourites

  --->MyFolder

RadTreeView2

Categories

-->MyFolder

At first Favourites will be empty and when user will select MyFolder it will be getting added into Favourites.

 

Please help me.

Hello Priyatam,

What I can suggest you is to subscribe to the SelectionChanged event of the second tree and add the selected items in the first tree view Favoirites item. Then if you want to load them when the user clicked on the expand icon, you can use Load on Demand functionality. I have prepared a sample project which demonstrates this behavior. You can additionally modify this approach so it can fit in your main application. I think this approach will be a good starting point for achieving your final behavior. 

In addition, the approach which I have used does not use binding. If you are using MVVM you can take a look at the Populating with Data -> Overview section in our documentation.
