List Box. On Click(EventArgs) Method
Raises the Click event.
protected: override void OnClick(EventArgs ^ e);
protected override void OnClick (EventArgs e);
override this.OnClick : EventArgs -> unit
Protected Overrides Sub OnClick (e As EventArgs)
The OnClick method selects or clears the check box of the item that is clicked. If the CheckOnClick property is set to
true, the check box is switched from a selected or cleared state the first time the item is clicked. Otherwise, the check box is switched only if the item is already selected.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnClick 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.
