ToolStripControlHost::OnSubscribeControlEvents Method (Control^)

 

Subscribes events from the hosted control.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

protected:
virtual void OnSubscribeControlEvents(
	Control^ control
)

Parameters

control
Type: System.Windows.Forms::Control^

The control from which to subscribe events.

Override the OnSubscribeControlEvents method to add or prevent the synchronizing of control events.

If you override and hook up events here, unhook them by using the OnUnsubscribeControlEvents method.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnSubscribeControlEvents method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnSubscribeControlEvents in a derived class, be sure to call the base class's OnSubscribeControlEvents method so that registered delegates receive the event.

The following code example demonstrates how to set up event handling for an event exposed by the hosted control. This code example is part of a larger example provided for the ToolStripControlHost class.

void OnSubscribeControlEvents( System::Windows::Forms::Control^ c )
{
   // Call the base so the base events are connected.
   __super::OnSubscribeControlEvents( c );

   // Cast the control to a MonthCalendar control.
   MonthCalendar^ monthCalendarControl = (MonthCalendar^)c;

   // Add the event.
   monthCalendarControl->DateChanged += gcnew DateRangeEventHandler( this, &ToolStripMonthCalendar::HandleDateChanged );
}
