    I have a Rad Tree View with around 2000 root nodes inside a RadTabControl. They are are bound to observable Collection items as I need to Drag and Drop to maintain order.

    When I select the tab item containing this Tree View. It takes around 40 seconds to load which as you can understand not acceptable to the end user.

    Is there any way to speed it up or what I am missing.

    Hi Ahmad,

     Have you tried using the UIVirtualization feature of the RadTreeView. Basically, when it is turned off, only the containers (RadTreeViewItems) that are in the viewable area will be initially generated and this will speed up the loading of the tree. You can examine this help article and also let us know if this helps you.
