Hello,
I have developed an application which allows the user to switch between
themes. I'm doing this by including the xaml file as a resource in my project and using the following code:
MainTheme.ThemeUri = new Uri("SilverlightApplication1;component/Themes/[ThemeName]/Theme.xaml", UriKind.Relative);
This worked well, untill I found these themes: http://timheuer.com/blog/archive/2010/05/17/silverlight-4-tools-released-and-new-application-templates.aspx
The difference is that these
themes consist of multiple files. So I made a Theme.xaml file that only includes MergedDictionaries so I could still use the code above. This is the Theme.xaml file for the Cosmopolitan theme.
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="CoreStyles.xaml"/>
<ResourceDictionary Source="SDKStyles.xaml"/>
<ResourceDictionary Source="Styles.xaml"/>
<ResourceDictionary Source="ToolkitStyles.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
However, when I run the c# code above I get the following exception:
System.Windows.Markup.XamlParseException: Failed to assign to property 'System.Windows.ResourceDictionary.Source'.
Just to be clear, using the MergedDictionaries method does work when I set it in my App.xaml:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Themes/Cosmopolitan/Theme.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
What am I doing wrong?
Thanks!
