I have a WPF ListBox control which displays items of an RSS feed. I occasionally check the source of the RSS feed for new items. Once I detect a new item I add it to the observable collection which immediately adds the new item to the ListBox display. Is there a way to 'slide in' the new item from the top, pushing down the existing item...

I'm generating a FlowDocument in code but I want it to apply dynamic styles defined in the resource dictionary. Even though I set the key using SetResourceReference, it seems like the resource lookup doesn't occur once I add the TextElements to the FlowDocument.

I see that to make a circle button, a Ellipse has to be defined with the same height and width. <Style x:Key="Button2" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <Control...
OK, I've figured out how to get my Grid of UI elements to zoom, by using LayoutTransform and ScaleTransform. What I don't understand is how I can get my View to respond to CTRL+MouseWheelUp\Down to do it, and how to fit the code into the MVVM pattern. My first idea was to store the ZoomFactor as a property, and bind to a command to adj...
