IRegisterMetadata.Register Method

Attaches design-time metadata to a particular control type.

Namespace:  Microsoft.Windows.Design.Metadata
Assembly:  Microsoft.Windows.Design (in Microsoft.Windows.Design.dll)

Syntax

'Declaration
Sub Register

'Usage
Dim instance As IRegisterMetadata

instance.Register()

void Register()

void Register()

function Register()

Remarks

The Register method is called during designer initialization.

Classes that implement the Register method should use the AddAttributeTable method to add metadata to the store.

Examples

The following code example shows how to implement the Register method. The Metadata class attaches an adorner provider to a control. For more information, see Walkthrough: Creating a Design-time Adorner.

' Container for any general design-time metadata to initialize. 
' Designers look for a type in the design-time assembly that  
' implements IRegisterMetadata. If found, designers instantiate  
' this class and call its Register() method automatically. 
Friend Class Metadata
    Implements IRegisterMetadata

    ' Called by the designer to register any design-time metadata. 
    Public Sub Register() Implements IRegisterMetadata.Register
        Dim builder As New AttributeTableBuilder()

        ' Add the adorner provider to the design-time metadata.
        builder.AddCustomAttributes(GetType(ButtonWithDesignTime), _
                                    New FeatureAttribute(GetType(OpacitySliderAdornerProvider)))

        MetadataStore.AddAttributeTable(builder.CreateTable())
    End Sub 

End Class

// Container for any general design-time metadata to initialize. 
// Designers look for a type in the design-time assembly that  
// implements IRegisterMetadata. If found, designers instantiate  
// this class and call its Register() method automatically. 
internal class Metadata : IRegisterMetadata

    public void Register()
    {
        AttributeTableBuilder builder = new AttributeTableBuilder();

        // Add the adorner provider to the design-time metadata.
        builder.AddCustomAttributes(
            typeof(ButtonWithDesignTime), 
            new FeatureAttribute(typeof(OpacitySliderAdornerProvider)));

        MetadataStore.AddAttributeTable(builder.CreateTable());
    }
}
