XamlType.LookupIsMarkupExtension Method


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

 virtual bool LookupIsMarkupExtension();
protected virtual bool LookupIsMarkupExtension ();
abstract member LookupIsMarkupExtension : unit -> bool
override this.LookupIsMarkupExtension : unit -> bool
Protected Overridable Function LookupIsMarkupExtension () As 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.
