How about subscribing to the ScrollViewer. The event arguments for it are pretty extensive, describing how much the ScrollViewer moved and what its new Vertical offset is.

DannyBeckett, before it was a clean step-by-step guide I agree with somewhat bad language and I am sure upvotes were given at that time.

Bob King Bob King I've gotten around it by just scaling up what is in the grid fonts mainly using animations. Not quite as simple, but basically what I wanted. I ran into an issue with scaling the font, that when scaling the font down the columns won't auto resize so they are still width of the bigger font size.

There's sadly a bug in the current build of the WPFToolkit that makes auto resize columns work strangely when they're mixed with Star sized columns. We see that behavior as well, and we've just never bothered to fix it. Thanks, actually if my above comments make no sense it was because I've been working on two separate issues, one with trying to figure out the top row and the other with zooming a datagrid.

I gave up on the top row thing and told the user they would need to adjust the UI. Maybe a late answer, maybe not the best way but one of the simplest.
