Re: Validation in TabControl
Not considered that, but like the sound. We are using fluent validation (the framework). I dare say changing how we validate would be massive change though Thanks will investigate whats involved.

Re: Validation in TabControl
Of course, the problem still stands, that if you have hidden tabs, how do you direct the user back to them to fix the errors :) On Wed, Apr 4, 2012 at 7:50 PM, Stephen Price step...@perthprojects.comwrote: Not considered that, but like the sound.

Re: Validation in TabControl
We are changing the colour of the tab text to red, when error is on that tab, or it's children. I like the idea of an error icon though. More accessibility friendly.
