TemplatedControlDesigner.OnTemplateModeChanged Method ()
Provides an opportunity to perform additional processing when the template mode is changed.
Assembly: System.Design (in System.Design.dll)
The ViewEvent event is raised by the designer host for certain actions on a control in the design surface. For example, an event is raised when the user enters or exits template editing mode for a control.
The TemplatedControlDesigner class supplies a default delegate to handle the ViewEvent event. Classes deriving from the TemplatedControlDesigner override the method to process events that are raised when the template mode changes for the associated control.
Themethod allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
The default delegate performs the updates that are required for a template mode change event in the base TemplatedControlDesigner class, and then calls the method. The base method in the TemplatedControlDesigner class returns without performing any additional processing for the event. If a class derives from the TemplatedControlDesigner and overrides the base method, the default delegate calls the override method in the derived class.
Use the InTemplateMode property to determine whether the control designer is in template editing mode currently.
Notes to Inheritors:
The default delegate that is supplied by the TemplatedControlDesigner class performs all updates necessary for the base class before calling the method. Override the method in classes deriving from the TemplatedControlDesigner to perform additional processing for template mode change events on controls in the design surface.
