TabControl doesn't display Validation error information correctly when switching tabs back and forth. Setting the Validation.ErrorTemplate on textboxes in a tabitem, then causing a validationrule to fire, the errortemplate displays correctly, however
After tabbing to another tab, then back, the controls in the error template no longer display.

.Net 4.0 has been out for a while now.. Could this be fixed to next version?

Microsoft please fix this bug, tabbed interfaces are so common, how can wpf not support it when data requires validation. I would give this bug a top priority!

This bug does not just affect TabContols. It will also manifest itself when you add and remove controls from a parent control. So it seems to be more to do with "losing focus" than "changing tabs"

The workaround with AdornerDecorator does not work when the tab page is initially invisible (not selected).

The AdornerDecorator workaround may not be acceptable since the error adorner will be clipped at the AdornerDecorator's boundary. This is a BUG that needs to be FIXED, please.

I had a similar issue with a TabControl with data bound controls on various tab panes.
The data bound controls were not always displaying as expected when switching between Tabs. (i.e. combo boxes were blank/greyed out when they should not have been)
Adding an AdornerDecorator to my Tab Pane template got rid of the problem.

Thank you for reporting this issue. Though this issue is under investigation, we will likely not have a fix available in .NET 4.0. We will update this bug again when we are able to fix the issue in a future release. Thanks!
