ComponentChanging event. The ComponentChanging event notifies the IComponentChangeService and registered event handlers that a particular component in the current design document is about to be changed. This event provides a widely accessible method to prevent a component from changing.provides data about a
A ComponentChanging event is raised before a component is changed. This event provides an opportunity for a designer to abort the change. Component designers typically raise the ComponentChanging event automatically. If a property cannot be changed, the method that handles the event can throw an exception. For example, if a designer file is checked into source code control, the handler of this event typically throws an exception if the user refuses to check out the file.
Aprovides the following information:
A Component property that indicates the component that is about to be modified.
A Member property that indicates the member that is about to be changed.
Notes to Inheritors:
A compiler error occurs if this class is specified as the base class of another class.
The following example demonstrates creating a.
' This example method creates a ComponentChangingEventArgs using the specified arguments. ' Typically, this type of event args is created by a design mode subsystem. Public Function CreateComponentChangingEventArgs(ByVal component As Object, ByVal member As MemberDescriptor) As ComponentChangingEventArgs Dim args As New ComponentChangingEventArgs(component, member) ' The component that is about to change: args.Component ' The member that is about to change: args.Member Return args End Function
