System.Windows.Forms.ToolBar.OnButtonDropDown Method

Raises the ToolBar.ButtonDropDown event.

Syntax

protected virtual void OnButtonDropDown (ToolBarButtonClickEventArgs e)

Parameters

e
A System.Windows.Forms.ToolBarButtonClickEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see [<topic://cpconProvidingEventFunctionality>].

The ToolBar.OnButtonDropDown(ToolBarButtonClickEventArgs) 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.

Requirements

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