Hello Mark,

Thank you for your feedback. I am glad that you resolved your issue and I believe that other community members may benefit from this as well.

Thanks again.

I'm sorry - I'm not convinced that building the styles using string concatenation and applying them into the XAML is the correct way to approach this, and certainly not something I'd expect you to be recommending to your customers.

I will stick with my theme based resource locator that I can use with XAML static bindings instead.

Thanks for looking into whether there was an alternative solution though.

Hello Mark,

I have been looking into your requirement and I can say that for every theme there should be a Style based on it. I created a sample project for you that shows how to use one Style and just change the name of the Theme that is currently selected. Please let me know if this helps you or you need further assistance on this matter.

Looking forward for your reply.

I read that post while investigating a solution, but it only covers the case where you have chosen a predefined style and are using that through the entire app.

I couldn't find anything that covers using the ThemeManager, ie, being able to exend the users currently selected theme, so that you can BasedOn the Currently Selected Theme, that is, one that's not known at design time.

That post covers building the name of the resource in the dictionary based on theme, essentially you'd have to be able to do something like DataPresenterCurrentSelectedTheme.CellViewPresenterStyle
