如何实现多路复用器控件

Question

I've implemented two different controls that allow a user to create and edit a filter for their data. Both controls have a DependencyProperty called Filter that implements my IFilter interface. One of the controls implements a RegularExpression filter, the other control implements a SelectionFilter (A list box where the select what items they want to filter on).

I'd now like to create a control that combines these filters into a CompoundFilterControl . The CoumpoundFilterControl should allow the user to select what type of filter they'd like to use.

Ideally I'd like my CompoundFilterControl to also have a Filter DependancyProperty. Depending on which Tab is selected, I'd like the Filter from the appropriate control to be selected.

I have no idea how to do this. The only thought I've had is impelementing the TabControl's SelectionChanged event and attempting to Dynamically bind the appropriate sub-control's Filter property to the CompoundFilterControl's Filter DependancyProperty. Is this correct?

如果我了解您要执行的操作，则可以让您的组合控件也实现IFilter，并且该IFilter实现仅在所选选项卡中调用该控件的IFilter接口
