    i'm trying to remove all checked items from my treeview. when i try to delete the items directly in my foreach-loop, an error occurs. the other way ist first to save all items from the checked items und dann traverse the tree to find each of this items - which is pretty slow. is there any better way to delete all checked items?

    Hello Monika Kogler,

    Please accept my apology for the delayed response. You can remove the selected / checked RadTreeViewItems while iterating through the RadTreeView  SelectedItems/ CheckedItems collection. If the current item has already been removed as a child of already removed item - continue to the next selected/checked item, else  - remove it.    

    I attached a sample solution and let me know if it satisfies your needs.

    I will be glad if I can further assist you.

    All the best,
