public:
 property System::Collections::ObjectModel::Collection<System::Windows::ResourceDictionary ^> ^ MergedDictionaries { System::Collections::ObjectModel::Collection<System::Windows::ResourceDictionary ^> ^ get(); };
public System.Collections.ObjectModel.Collection<System.Windows.ResourceDictionary> MergedDictionaries { get; }
member this.MergedDictionaries : System.Collections.ObjectModel.Collection<System.Windows.ResourceDictionary>
Public ReadOnly Property MergedDictionaries As Collection(Of ResourceDictionary)

Property Value

The collection of merged dictionaries.

Examples

The following example specifies two ResourceDictionary elements to be merged into the primary ResourceDictionary.

<Page.Resources>
 <ResourceDictionary>
 <ResourceDictionary.MergedDictionaries>
 <ResourceDictionary Source="myresourcedictionary.xaml"/>
 <ResourceDictionary Source="myresourcedictionary2.xaml"/>
 </ResourceDictionary.MergedDictionaries>
 </ResourceDictionary>
</Page.Resources>

Remarks

Dictionaries are merged by adding a ResourceDictionary to the generic collection referenced by MergedDictionaries. A merged ResourceDictionary does not have resource elements defined within it in markup. Instead, the merged dictionary is a ResourceDictionary with no markup child elements defined (or with no elements added through code), but with a URI specified for Source. The Source designation enables the merged dictionary to come from an external source, such as a separate resource assembly that ships with the application, "loose XAML", or a specific localization or global resources assembly.

Specifying resource elements within a ResourceDictionary that has Source specified is not supported.

Lookup behavior within the MergedDictionaries collection will search the last-added ResourceDictionary first, and the search stops as soon as a requested key is found. Duplicate keys across the collection of merged dictionaries are not illegal. For more information on merged dictionary behavior, see Merged Resource Dictionaries.

XAML Property Element Usage
