Over at nostatic.com, there is an example of <a href=”http://notstatic.com/archives/118″>using MarkupExtension</a> that that we can access some custom code functionality directly from the XAML.
In his example, the following XAML accesses a random number generator within the code.
<Button> <Button.RenderTransform> <RotateTransform Angle="{l:RandomNumber Min=0, Max=360}" /> </Button.RenderTransform> </Button>
Pretty cool. Apparently it only works when it isn’t placed inside a template… which makes it of limited usefulness, but still pretty neat.
