When I use Dock Panels, I have question. My target: I want use noperisten object's detailView as Master to filter one persistent objects' listView. for example: I have peristent object: 'DemoTask' and noperistent object 'DemoTaskFilter'. 'DemoTask' have two properties: subject and StartDate. 'DemoTaskFilter' have two properties: DateFrom and DateTo. I use 'DemoTaskFilter's detailView as Master. I want it can filter the DemoTask listView' CollectionSource when I change the 'DemoTaskFilter' DateFrom and DateTo. When the 'DemoTaskFilter' DockPanel show at first, the filter work fine. But when I change the value of DateFrom or DateTo, the filter doesn't work. If I close the filter,and open it again, it work fine. I want it can filter the DemoTask listView' CollectionSource when I change the 'DemoTaskFilter' DateFrom and DateTo. How to realize it? By the way, I find the application have two 'New' action when the 'DemoTask' listView show. Why? How to slove it?
