I have two ItemsControls, one a ListView, and one a custom control I am developing.
I have set the ItemsControl.ItemsSource property of both controls to the same IEnumerable object, in this case, a List.
I apply a filter to the ItemsControl.Items property of my custom control (this.Items.Filter = myFilter) and my control refreshes as expected, showing only the items that match the filter.
However, the ListView using the same IEnumerable object for its ItemsControl.ItemsSource property also refreshes, showing only the items that match the filter I applied to my custom control.
Can anyone tell me how to keep the filter in my custom control from affecting the items in my listview?
