Windows Phone ApplicationBar BackgroundColor property style XamlParseException

问题

I had a lot of pages in my application and I had decided to make a global ApplicationBar style in App.Resources:

<Style TargetType="shell:ApplicationBar">
    <Setter Property="BackgroundColor" Value="#006699" />
</Style>

However, when I tried to start the app, VS gave me an error:

The property 'BackgroundColor' was not found in type 'Microsoft.Phone.Shell.ApplicationBar'.

This isn't true - ApplicationBar.BackgroundColor Property. What's the problem?

回答1:

I believe, ApplicationBar properties cannot use Binding or styling the way you're trying, as it is not a silverlight control. Although you can put the whole applicationbar as a resource. Like so

<shell:ApplicationBar x:Key="MyAppBar" IsVisible="True" BackgroundColor="#006699">
         <shell:ApplicationBarIconButton IconUri="/Images/image.png" Text="image"  IsEnabled="True"/>  
</shell:ApplicationBar>

EDIT: Or you could just put this in the resource if you want your application bar color to change.

<shell:ApplicationBar x:Key="MyAppBar" IsVisible="True" BackgroundColor="#006699">
</shell:ApplicationBar>

And add buttons from code behind. although, I haven't come across a scenario where this would help.
