I'm trying to make a Hyperlink that contains text with super- and/or subscripts. I've found two ways to do this, and both of them suck. Solution #1: use Typography.Variants. This gives a terrific superscript... for some fonts. <StackPanel> <TextBlock FontFamily="Palatino Linotype" FontSize="30"> <Hyperlink>R<Run Typography.Varian...
WPF has the Typography.Variants attached property that lets you do superscript and subscript. However, it only works for some fonts. For other fonts, the variant is utterly ignored, and the text is shown normally. (Code sample and screenshot here) Since it silently falls back to a no-op, I have no idea that anything went wrong; but my u...
I want to produce some library code that will be included into WPF applications. The library may pop up a Window, depending on circumstances. I can define the Window in XAML, but I'd like to treat the XAML as a template. At runtime, at the time the Window is being created so that it can be displayed, I want to replace certain tags in t...
I'm very happy with my small collection of Blend behaviors, actions and triggers - they are easy to use and powerful. But I still can't figure out how to avoid applying them on per element basis. For example, if I have a behavior as such: <Rectangle> <i:Interaction.Behaviors> <il:MouseDragElementBehavior/> </i:Interactio...

Is there a way to force a WPF window to use a rubber band (no live preview of contents during resize) when resizing? I realize this is usually a user preference on Windows but my application uses D3D windows and there is significant flicker when resizing (particularly from the top left corner outward). -- I should have mentioned I am ...
There are some projects that could use WPF at work, for the sake of adopting new technologies. But the problem is, I can't jump start WPF easily. I recognize the learning curve is steeper than Winforms. Though even with Winforms one can start doing UIs and programmatically customize them in a day. So the problem is: I don't have any ...

I'm writing a WPF app, and I want some of my hyperlinks to be the default blue, and others to be green. No problem -- I can just set Foreground: <TextBlock><Hyperlink Foreground="#0C0">Mark as done</Hyperlink></TextBlock> The trouble is, when I do this, the hover effect goes away. In a normal Hyperlink, when I move the mouse over the ...
