Thank you. It's a thought. But we cannot use this approach to turn off styles for forms whose codes mustn't be changed. Eg. we need clicking a button to switch the theme.

to change the entire Applicatin theme?

Kishore Kumar 2010-10-13 04:43:06

Yes, somehow like that, but I just make the problem "small", for button controls only.

for that you have to create different resources file for each theme(in your case only for Button) and you have load that theme resource file dynamically at runtime (Application Resource). To implement that you have to use DynamicResource instead of StaticResource

I understand your suggestion, Kishore. But still need to make myself clearer: I want a style "undo" feature. Like typing in MS Word, when you try some formation (bold/underline) - should read as applying a style - and later you undo it to return to initial state. I seek for the technique to undo the style applying. Your suggestion require the knowledge of the currently-used theme/style.

There are two option for this. 1. Use Toggle button and create your own style and change the background color combination for Checked and Unchecked State (ex. if the toggle button is checked let it be red and if not black). 2. Create a custom button with some property to accept the background color or property to identify the state of the button. Based in on the property you create triggers to change the color .
