The code that is to be executed in the RoutedUICommand.CanExecute and RoutedUICommand.Execute methods depends on what UI element was used. How can I achieve this differentiation. I was thi...
Hi, I'm trying to write a simple WPF app that has two ellipses, joined by a line, like you might see in a network graph. When the ellipses are animated, I just want the joining line to automagically 'stick' to the canvas locations of the two ellipses that the line joins. The XAML is just a canvas: <Window x:Class="UIDataBindingDemo.W...

This may seem like a high-level question. But that is because I'm unfamiliar with cutting edge ASP.net and even less with this behemoth called Sharepoint. So please bear with me.. First off is it possible to take functional custom WPF controls which contain certain unmanaged subcomponents that do DirectX rendering (for performance reas...

Is it possible to use a JPG file as a Window Icon using strictly XAML? I've found examples where you can use a BitmapFrame within C# to generate an ImageSource on the fly (which is then assignable to the Icon property), but I'd love to do something like: <Window.Icon> <SomeXAMLThatLetsMeUseJpg Source="MyJpg.jpg" /> </Window.Icon> ...

I'm working on a web-enabled media center which will be able to load video feeds into a gallery style view. (like Cooliris) Rather than loading thumbnail images of each video, I plan to load the actual video so it can be played in-place and/or popped out to fullscreen. This means I need to host a bunch of flash-player instances 'inside...

This problem stems from not being able to get my TextBlock to wrap. Basically as a last-ditch attempt I am setting MaxWidth on my container grid's columns. I was surprised to find that my child label and textbox still do whatever they want (bad children, BAD) and are not limited by my grid column's MaxWidth="200". What I'm really tryi...

I'm rendering text using FormattedText, but there does appear to be any way to perform per-char hit testing on the rendered output. It's read-only, so I basically only need selection, no editing. I'd use RichTextBox or similar, but I need to output text based on control codes embed in the text itself, so they don't always nest, which ma...
