DateTimePicker::OnDropDown Method (EventArgs^)

 

Raises the DropDown event.

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

protected:
virtual void OnDropDown(
	EventArgs^ eventargs
)

Parameters

eventargs
Type: System::EventArgs^

An EventArgs that contains the event data.

The DropDown event occurs when the drop-down calendar is shown.

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

The OnDropDown 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 OnDropDown in a derived class, be sure to call the base class’s OnDropDown method so that registered delegates receive the event.
