WPF 4.0 notoriously fixed the blurry text issue. Setting TextOptions.TextFormattingMode="Display" uses pixel hints to line up characters, which works really well to improve clarity. However, it does not work while the program is running as a Windows service in session 0; the text goes back to "Ideal" rendering, which at small sizes is c...
I've got a DataGrid control that's within a Grid layout container, and I can't seem to get the auto-scroll on the datagrid itself to work. I can wrap the datagrid around a ScrollViewer and thus adding the scroll bar, but the auto scrolling doesn't work. So right now when new entries are added to the datagrid, the datagrid just expands ve...

I've noticed in WPF, the default font size of 12 points is roughly equivalent to 9 points in "normal" applications (e.g. WordPad), 10 pt in WPF is roughly 7 pt standard, and when I try to match the default font size of 10 pt in WordPad in WPF, I've found 13 is the closest. First of all, why does WPF use such bizarre non-standard font si...
I've read several articles about how to use Attached Properties to bind to the value of a PasswordBox in WPF. However, every article also references the .NET documentation which explains why the PasswordBox was not made bindable in the first place. I do not consider myself a security expert by any means, but I figure that someone at Mi...

WPF's RTB is terribly slow when working with any realistic amount of text. And by realistic amount, I mean what you'd expect any text editor to be able to handle (100kb? At least) without showing any signs of slowness. This expected RTB behavior is not the case for me. Actually, the control works pretty much like it should when text is ...
