Is there any way to use the VisualStateManager with my ChildWindow subclass? Calls to VisualStateManager do nothing, and the googling I did implied the only way to achieve this is with manual calls to Storyboards. That's so much sloppier and prone to error. Has anyone found a way to achieve it? Updated with example code. To use it, just...

I wrote an IComparer<T> that makes sure blanks are always sorted downward, but I can't figure out how to apply it to the columns of my DataGrid. Note that the initial sort of the DataGrid, which I'm doing with...
Hi all, First question here. Anyway, here it goes: I have a XAML Windows with a lot of DatePicker controls (DatePicker from the WPFToolkit on CodePlex). Every DatePicker has a default Value of 1/1/1990 and if no other date is selected, I want (or rather my boss :-) ) to display the Text in gray italic and not in Black. Thus, it makes it...
