XamlType.LookupIsMarkupExtension Method

Returns a value that indicates whether this XamlType represents a markup extension.

Namespace:  System.Xaml
Assembly:  System.Xaml (in System.Xaml.dll)

protected virtual bool LookupIsMarkupExtension()

Return Value

Type: System.Boolean
true if this XamlType represents a markup extension; otherwise, false.

This method can be invoked by calls to IsMarkupExtension.

The default implementation consists only of this call:

return CanAssignTo(XamlLanguage.MarkupExtension);

Override this method if you want IsMarkupExtension to use different logic.

In XAML specification terms, this type must be assignable to x:MarkupExtension in order to return true for IsMarkupExtension.
