XamlType.LookupMarkupExtensionReturnType Method

Definition

Returns a value that provides the type information for the returned ProvideValue of this XamlType, if it represents a markup extension.

protected:
 virtual System::Xaml::XamlType ^ LookupMarkupExtensionReturnType();
protected virtual System.Xaml.XamlType LookupMarkupExtensionReturnType ();
abstract member LookupMarkupExtensionReturnType : unit -> System.Xaml.XamlType
override this.LookupMarkupExtensionReturnType : unit -> System.Xaml.XamlType
Protected Overridable Function LookupMarkupExtensionReturnType () As XamlType

Returns

XamlType

A XamlType object for the return type for markup extension usage; otherwise, null, if this XamlType does not represent a markup extension.

Remarks

This method can be invoked by calls to MarkupExtensionReturnType.

The default implementation returns a XamlType on the basis of reading MarkupExtensionReturnTypeAttribute. It can also check BaseType for the attribute if no attribute is found on the immediate underlying type. If a value is not available, it returns null.

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