Called by the design host when the user clicks the associated control at design time.
Assembly: System.Design (in System.Design.dll)
abstract OnClick : e:DesignerRegionMouseEventArgs -> unit override OnClick : e:DesignerRegionMouseEventArgs -> unit
The ViewEvent event is raised by the design host for certain actions on a control in the design surface. For example, an event is raised for the following conditions:
The user clicks the control.
The control designer paints on the design surface.
The user enters or exits template editing mode for the control.
The ControlDesigner class supplies a default delegate to handle the IControlDesignerView.ViewEvent event. Classes deriving from ControlDesigner override the method to process events that are raised when the user clicks a control.
The method 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 implementation of the method returns without performing any processing.Notes to Inheritors
Override the method in a class deriving from the ControlDesigner class to handle design-time click events on the control. If e is not null, the clicked region, if any, is specified in the Region property.
The following code example shows how to use a handler for the event in a clickable region of the control and use a DesignerRegionMouseEventArgs object to identify the region that is being clicked.
This code example is part of a larger code example for the EditableDesignerRegion class.
