winrt-xaml

问题 Ok. I know wpf and am learning programming windows runtime via c# and xaml. Both use xaml that have the same namespace. Win rt is new and has the same namespace declared at the root element. What are the similarities and differences. 回答1: Here are some of the differences between WPF and WinRT: Different XML namespace declaration in XAML code (Instead of using a clr-namespace:/assembly= qualifier set for code-to-XAML namespace references, you use the using: qualifier. XAML namespaces no longer

问题 I have a MediaElement and a TextBlock next to it. But when I set MediaElement to fullscreen, this TextBlock disappears. Can anyone share a solution? <MediaElement Name="player" Margin="10,5" AreTransportControlsEnabled="True" /> <TextBlock Margin="10"/> 回答1: As I have said in this thread, when we are in the Full Window mode, it will go to the FullWindowMediaRoot layer with the MediaTransportControls.

问题 On Windows Phone there's a marketplace review task. Is there any way to implement the equivalent functionality in WinRT apps? I realize that there's the "rate and review" button in the Charms bar, however, this is not what I need, as I want to integrate a button inside the app to launch the review UI.

Is there any way to do this for

问题 In Windows 8, you were able to create your own themes for your application (here's a tutorial). In Windows 8.1 Applications, themes are handled differently: you can change them at run-time and set a theme for a specific control in your XAML (if you don't want to apply the theme to the whole Application).
