TreeView.OnMouseEnter Method

Provides handling for the MouseEnter event.

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

protected override void OnMouseEnter(
	MouseEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseEventArgs
A MouseEventArgs that contains the event data.

The OnMouseEnter method is called before any event handler for the MouseEnter is called. This method allows derived classes to handle the MouseEnter event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation does not change the handled state of the event.

Notes to Inheritors

If you override OnMouseEnter, you can prevent registered delegates from receiving events by setting Handled to true. For more information about routed events and the Handled property, see Events Overview for Silverlight.
