Occurs when a component has been changed.
public:
event System::ComponentModel::Design::ComponentChangedEventHandler ^ ComponentChanged;event System.ComponentModel.Design.ComponentChangedEventHandler ComponentChanged;member this.ComponentChanged : System.ComponentModel.Design.ComponentChangedEventHandler Event ComponentChanged As ComponentChangedEventHandler Event Type
Remarks
This event occurs when any component on the form changes. This event will not occur during form load and unload, because changes are expected at this time.
Note
A DesignerTransaction can raise multiple ComponentChanged events. Some ComponentChanged event handlers can interfere with expected sequences of events, such as if your code alters the values of properties while a transaction is occurring. A ComponentChanged event handler can also impair performance if it draws after each change while a DesignerTransaction is in progress. In order to allow a DesignerTransaction in process to complete without interruption or interference by your ComponentChanged event handler, you can test the state of the InTransaction property, and defer handling the change events until the completion of the transaction by adding a DesignerTransactionCloseEventHandler which will raise your ComponentChanged event handler and remove itself upon completion of the transaction.
