    I'm trying to apply filter in the rad tree list view, but i want one thing to not to be happend.

    Please find the attached image of my result after filtering.

    In the image i applied filter to "Project Technical Leaders" including its only next childs.

    Now, what I want is that, its child should not be expanded.
    should be visible only in collapsed form.
    Because if we expand them, it take a lot of time to fetch data for all the child, but as filtering is applied, that data is not visible.

    Please help me as soon as possible.

     You can use RadTreeListView CollapseHierarchyItem() method to collapse specific data item.
