Examples

The following code example shows how to associate the ActivityDesigner1 custom activity designer with a custom activity. For more information about how to create custom activity designers, see How to: Create a Custom Activity Designer.

internal class Metadata : IRegisterMetadata  
{  
    private AttributeTable attributes;  

    // Called by the designer to register any design-time metadata.  
    public void Register()  
    {  
        AttributeTableBuilder builder = new AttributeTableBuilder();  

        // Add the custom attributes to associate the ActivityDesigner1 custom designer  
        // with the custom activity MyActivity.  
        builder.AddCustomAttributes(  
            typeof(MyActivity),  
            new DesignerAttribute(typeof(ActivityDesigner1)));  
        MetadataStore.AddAttributeTable(builder.CreateTable());  

    }  
}  

Remarks

The metadata store contains custom attribute metadata, such as the association between designers and types. Custom attributes can be defined in an AttributeTable and added to the metadata store. After the attributes are added, they will appear in calls made to TypeDescriptor.
