Is it possible to change property  of a component in some visual state without having full ControlTemplate in resource?
I need to change visual state property of Text (make it green in Valid state )for a MaskedTextBox.
So I believe I need to edit Template and do my stuff. But it means I need to have full ControlTemplate in resource.
How to achive this with minimum code in XAML file?
May be you can template this property in component itself (similar to ControlOuterBorder_Focused or ControlForeground_Disabled), so I will be able to apply style without modifing whole control template?  Something like ControlValidForeground??

Hello Vit100,

There are couple of ways to achieve this. You can either handle the ValueChanged event and set the Foreground proeprty of the RadMaskedTextbox to Green. You can also use a style and bind the foreground property of the control to its Value property with a IValueConverter which will return a different brush depending on the value and how it changes.

All the best,
