    </ASPxTreeList>
    
    protected void ASPxTreeList1_HeaderFilterEditorInitialize(object sender, ASPxTreeListHeaderFilterEditorInitializeEventArgs e) {
        if (e.EditorType = DevExpress.Web.GridHeaderFilterEditorType.Calendar){
            // your code
        }
    }
    

    Note that the HeaderFilterEditorInitialize event supports only editors that do not send callbacks.
