AttributeTableBuilder.CreateTable Method
Creates an attribute table that contains all the attribute definitions provided through AddCustomAttributes calls.
Namespace: Microsoft.Windows.Design.Metadata
Assembly: Microsoft.Windows.Design.Extensibility (in Microsoft.Windows.Design.Extensibility.dll)
Syntax
'Declaration
Public Function CreateTable As AttributeTable
public AttributeTable CreateTable()
public:
AttributeTable^ CreateTable()
member CreateTable : unit -> AttributeTable
public function CreateTable() : AttributeTable
Return Value
Type: Microsoft.Windows.Design.Metadata.AttributeTable
An attribute table that can be used to define design-time metadata.
Remarks
The table is a snapshot of the current state of the attribute builder. Any subsequent AddCustomAttributes calls are not included in the table. If callback methods were used to declare attributes, those methods will not be evaluated during CreateTable. Instead, the table will contain those callbacks and will evaluate them as needed.
Examples
The following code example shows how to build an AttributeTable and add it to design-time metadata. 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 IProvideAttributeTable. If found, designers instantiate
' this class and access its AttributeTable property automatically.
Friend Class Metadata
Implements IProvideAttributeTable
' Accessed by the designer to register any design-time metadata.
Public ReadOnly Property AttributeTable() As AttributeTable _
Implements IProvideAttributeTable.AttributeTable
Get
Dim builder As New AttributeTableBuilder()
' Add the adorner provider to the design-time metadata.
builder.AddCustomAttributes(GetType(ButtonWithDesignTime), _
New FeatureAttribute(GetType(OpacitySliderAdornerProvider)))
Return builder.CreateTable()
End Get
End Property
End Class
