All, I am coming from a primarily ASP.NET background, but have experience with Windows forms as well.

All I wanted was different bindings on different tabs, so switching tabs would toggle command availability. I thought CommandBindings worked that way. But I've spent the last while trying to get this simple sample to work. Either I fundamentally misunderstand (and that would not be a first) or something's wrong. I add a CommandBinding...

I now need to show that element as selected. sample code I found online changes the opacity of a drawingvisual from 1.0 to 0.4 when clicked, but this is not...

I'm using DevPartner to track down memory leaks in a long-running .NET/WPF app. DevPartner tells me what classes are being leaked over time (primarily WeakReference, but also EffectiveValueEntry and WeakDependencySource). What I need to know is what other object(s) still have references to these in order to prevent them from being garb...
I would like to animate when items are added/removed from an ItemsControl. Does anyone have ideas/links on how to achieve this? I think fading-in should be doable by attaching an animation to the Loaded event. Fading out seems it would be much harder, though. As for sliding, when an item disappears, I want the rest of the items to slid...

I've created a ToggleButton to show and hide a piece of UI and I've sent its Content to an icon.
