This works for me in Silverlight 3, but when I try it in Silverlight 4 it crashes - has anyone else tried it?

Emil,

Thanks for the post. Consider the following scenario: You have a custom control library (called: "SomeOtherLibrary") with one customized UserControl in it, called "CustomControl." CustomControl merges a ResourceDictionary from an assembly called "External_ResourceLibraries," like so:

<UserControl.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/External_ResourceLibraries;component/BasicStylesDictionary.xaml" />

ResourceDictionary.MergedDictionaries>


        ResourceDictionary>

    UserControl.Resources>



Let's say that you look at that customized UserControl in Blend and experience no problems. Now let's say you try to use that customized UserControl in your web application like this:




<SomeOtherLibrary:CustomControl />


Should the UserControl that creates an instance of "CustomControl" have to have a reference to the External_ResourceLibraries assembly in order to run? I have an application that works in this way, and need to know if this is the appropriate way of using MergedDictionaries in custom UserControl libraries. This process seems redundant, inefficient, and illogical. Can you help me understand why this custom UserControl can't be used in another UserControl's assembly without explicit references to the External_ResourceLibraries that it attempts to merge together?
Thanks,
- Aaron

I've tried to use it on a generic.xaml but it doesn't work.
My struct is like this:

    SilverlightClassLibrary1
    
        Themes
        
            generic.xaml
        
        
        CT
        
            MyTabControl.xaml
        
        
        MyTabControl.cs
    
    

MyTabControl is my custom control that inherit ItemsControl. MyTabControl.xaml contains all ControlTemplate(s) and properties definition.
I tried to insert in generic.xaml:


    
    
        
            <ResourceDictionary.MergedDictionaries> 
        
        
                <ResourceDictionary Source="/local;/CT/MyTabControl.xaml" /> 
        
        
            ResourceDictionary.MergedDictionaries> 
        
    


But it doesn't work, why? Thanks.

Thank you Assaf, it is useful to know that!

I've came across another issue -
When the external assembly name contains dots (for example AssemblyNamePart1.Part2), an error is thrown.
After removing the dots (e.g. AssemblyNamePart1_Part2), everything worked fine.

Hi sidhu,
the problem is that the code was compiled with Silverlight 3 Beta. For Silverlight 3 RTW you need to put a slash '/' at the beginning of the source path. Like this:
 


Hope that helps!

I downloaded your source code and tried to run it. I got runtime errors in InitializeComponent(xmlParserException with message  Attribute ExternalResources;component/DataResources.xaml value is out of range. [Line: 8 Position: 44]) for both
 

  
It worked fine if i comment both these lines. Is there any settings I need to change? or copy any resource files?

Hi Emil,

I am trying to do the following:
I have a resource project ResDict with 2 files: styles.xaml and assets.xaml.
styles.xaml needs the info in  assets.xaml (brushes).
styles.xaml is used in another SL project MainPrj.

following your indications, I was able to use the styles in styles.xaml in the MainPrj, when styles.xaml doesn't use the brushes in assets.xaml.

how can I use the definition in assets.xaml within styles.xaml in my MainPrj?

ADDITIONAL INFO:

Build action for style.xaml and assets.xaml is Resource.

Code in style.xaml:
 <ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="ResDict;component/assets.xaml"/> ResourceDictionary.MergedDictionaries> 
Code in App.xaml in PrjMain
 <Application.Resources>     <ResourceDictionary Source="ResDict;component/styles.xaml" /> 
Application.Resources> 
Thank you very much in advance for your help!

@Pavel, did you look at the source code? You can see that I included DataResources.xaml as a Resource in external assembly (ExternalResources) and then use it without any problems in MergedResourceDictionaries assembly. Take a look at it and let me know whether there is something not clear.
@Ryan, there is no problem to do that. Here is what you need to do:                            1             <ResourceDictionary Source="MergedResourceDictionaries;component/SubFolder/SubBrushResources.xaml" />          
                    2             <ResourceDictionary Source="/SubFolder/SubBrushResources.xaml" />          
    

If you include your resources as a Resource (build action) you should you use the snippet on the first line where: MergedResourceDictionaries is the assembly name
SubFolder is the name of the sub folder where you put your resources
SubBrushResources.xaml is the name of your resource dictionary file

If you include your resources as a Content (build action) you should use the snippet on the second line where:
SubFolder is the name of the sub folder where you put your resources
SubBrushResources.xaml is the name of your resource dictionary file

Does this make sense to you?

Hope that helps!

Including resources as Resource does not work when I try to use it in an external assembly. May work in WPF~21~3f I kept the ResourceDictionary as a Page and everything worked fine.~3cbr /~3e

1	<ResourceDictionary Source="MergedResourceDictionaries;component/SubFolder/SubBrushResources.xaml" />
2	<ResourceDictionary Source="/SubFolder/SubBrushResources.xaml" />
