XamlType.LookupAllowedContentTypes Method

Returns a list of the types that are usable as the ContentProperty value for this XamlType.

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

protected virtual IList<XamlType> LookupAllowedContentTypes()

Return Value

Type: System.Collections.Generic.IList<XamlType>
A list of possible content types.

This method can be invoked when a caller gets a value from AllowedContentTypes.

Types that evaluate as CanAssignTo for a specific content type are not considered multiple types for purposes of AllowedContentTypes.

The default implementation can use other properties of XamlType (ContentWrappers, ContentProperty, or ItemType) to obtain a result. The Lookup overrides for the preceding property list can also be invoked in this determination.

Override this method if you are not relying on default internal CLR reflection and are using metadata or other techniques for reporting the XAML type system information or schema information of a type.
