    First, I have prepared my data in a radTreeView control.
    Then, how assign treeview to RadListFilterPopup?

    Please refer the pciture from attachment.
    Any way can be done?

    RadHostItem h = new RadHostItem(this.radTreeView1);

    void radGridView1_FilterPopupRequired2(object sender, Telerik.WinControls.UI.FilterPopupRequiredEventArgs e)
        if (e.Column.Name == "Store")
            e.FilterPopup = new RadListFilterPopup(this.radTreeView1, true);

    Hello Stanley,

    Thank you for writing.

    The tree in RadListFilterPopup cannot be replaced, however it can be accessed and modified. Here is a sample, where I am clearing all nodes and I am adding new ones:
    void radGridView1_FilterPopupRequired(object sender, Telerik.WinControls.UI.FilterPopupRequiredEventArgs e)
        if (e.Column.Name == "Name")
            RadListFilterPopup popup = e.FilterPopup as RadListFilterPopup;
            for (int i = 0; i < 10; i++)
                popup.MenuTreeElement.TreeView.Nodes.Add("Node Name " + i);

    I hope this helps. Let us know if you have any other questions.
