ToolStripItem.OnClick(EventArgs) Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Source:

ToolStripItem.cs

Raises the Click event.

C#

protected virtual void OnClick(EventArgs e);

Parameters

e

EventArgs

An EventArgs that contains the event data.

Examples

The following code example demonstrates how to override the OnClick method. This code example is part of a larger example provided for the ToolStripItem class.

C#

// The method defines the behavior of the Click event.
// It simply toggles the state of the clickedValue field.
protected override void OnClick(EventArgs e)
{
    base.OnClick(e);

    this.clickedValue ^= true;
}

Remarks

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.

Notes to Inheritors

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