TreeView.OnKeyPress(KeyPressEventArgs) Method

Definition

Raises the KeyPress event.

protected:
 override void OnKeyPress(System::Windows::Forms::KeyPressEventArgs ^ e);
protected override void OnKeyPress (System.Windows.Forms.KeyPressEventArgs e);
override this.OnKeyPress : System.Windows.Forms.KeyPressEventArgs -> unit
Protected Overrides Sub OnKeyPress (e As KeyPressEventArgs)

Parameters

e
KeyPressEventArgs

A KeyPressEventArgs that contains the event data.

Remarks

If the Handled property is set to false, the TreeView control will select the first item that begins with the value of the KeyChar property of e.

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

The OnKeyPress 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 OnKeyPress(KeyPressEventArgs) in a derived class, be sure to call the base class's OnKeyPress(KeyPressEventArgs) method so that registered delegates receive the event.
