I have a problem which could be solved by redusing filter distinct list (PART_DistinctValuesList) height. Problem occurs when application is running in "small screen resolution" browser (xbap), filter won't be fit inside of browser window when there are lot of items in distinct list. See picture filter_opened_when_run_in_browser.png about that problem.
Is there any easy way to change all filters list max height? I found this help http://www.telerik.com/forums/gridview-filter-fbfab7e2d676
but it didn't work when opened first time (see picture filter_first_open_maxheight_set_to_list.png) and works fine after second open (see picture filter_after_first_maxheight_set_to_list.png).
