    Is it possible to​ select multiple nodes in TreeView after clicking on one node and then dragging mouse just like we do in GridView. Basically I need to implement DragElementAction property in Treeview but cannot find it in this control.

    Any help would be greatly appreciated.

    Hello Ashna,

    RadTreeView doesn't support drag selection mode. However, you can implement such with custom logic in the treeview's mouse event handlers. I prepared a small example that demonstrates a possible approach, but please keep in mind this implementation is not well tested and I cannot guarantee that it will work in all expected scenarios.
