This seems to be a problem I struggle with on a recurring basis. I've got a control that has a hierarchy like: <grid> <stackpanel> <expander> <textbox> The problem is that when a bunch of text is bound to the textbox, it just expands off into infinity. The behavior I want of course is for the textbox to fill ...

I have a simple, horizontal <Line> element. This line has a RotateTransform applied to it, which slants the line at whatever angle I choose.

The title pretty much describes it. If I resize my WPF app so that it stretches over two monitors in a dual monitor setup, and resize it back, there will be a ghost window in the second monitor that does nothing, but is still moved when I move the original window in the first screen. Has anyone had issues like this? I think its a refres...

I took a look at Blend 3 quickly, dragged a Grid into my Window but found no options to actually create, say, a 4 x 10 grid with labels. I ...
