    Hello,
    I am applying filtering to a column in the treelist but upon filtering, only the top level rows are kept.Rows in the final results cannot be expanded or collapse. I would like to display all the children rows for the filtered data. How can I achieve this?
    Thanks

    Hello,

    When you filter, then all the nodes in the TreeListView satisfying the filter will be shown. If their children cover the filtering criteria, then they can be expanded and accessed. If their children should not be shown (as they did not pass the filter), then they cannot be expanded. 

    You can check this behavior on our TreeListView WPF Demos.

    Hello,

    About Seylom's question, can user override the built-in filter logic to achieve it?

    Thanks.

    Hi,

    I am afraid that this cannot be done with modifying the built-in filtering logic. You can implement your own custom filtering instead.
