DefaultEventAttribute Class
Specifies the default event for a component.
Assembly: System (in System.dll)

For more information, see Attributes Overview and Extending Metadata Using Attributes.
The following example defines a collection class named MyCollection. The class is marked with a DefaultEventAttribute that specifies CollectionChanged as the default event.
The next example creates an instance of MyCollection. Then it gets the attributes for the class, extracts the DefaultEventAttribute, and prints the name of the default event.
Public Shared Function Main() As Integer ' Creates a new collection. Dim myNewCollection As New MyCollection() ' Gets the attributes for the collection. Dim attributes As AttributeCollection = TypeDescriptor.GetAttributes(myNewCollection) ' Prints the name of the default event by retrieving the ' DefaultEventAttribute from the AttributeCollection. Dim myAttribute As DefaultEventAttribute = _ CType(attributes(GetType(DefaultEventAttribute)), DefaultEventAttribute) Console.WriteLine(("The default event is: " & myAttribute.Name)) Return 0 End Function 'Main
