Windows Phone ApplicationBarIconButton not displaying icons

So you’ve added an ApplicationBarIconButton to your Windows Phone 7 Silverlight page and you can’t get the icons to display. You’ve tried every path under the sun, pack uri’s, relative uri’s, checked the case everything – still no dice. You’ve put an image control on the page and the image displays fine. So WHY!

Answer: you need to set the image build action to “Content” but it defaults to “Resource”.

Text="delete all"/>


I’ve logged this as a bug, but I think its by design. I’m trying to find out why.

    Yes thanks…. actually I recently did a tutorial for adding images to the toolkit DatePicker control.. and the guy explicitly said "Don't forget to change the Build Action"… and I forgot.  So it looks like this behavior holds true for all images copied into the project.

    This is specific for ApplicationBarIconButton! Other controls can display images that have Resource instead of Content as Build Action.

    the main difference of Content and Resources is, that with Build Action=Resource the images are loaded at assembly load. With Build Action=Content the load is defered until usage.

    So it's a question of performance.

    The URI also is different:

    You have saved me from doubting my sanity. Thanks!

    Still can't get that "Resource" style Uri working but I'm fine with the "Content" style setup.

    Oh, thanks again.
