RichTextBox.OnMouseEnter Method

Silverlight

Called before the MouseEnter event occurs.

Namespace:  System.Windows.Controls
Assembly:  System.Windows (in System.Windows.dll)
protected override void OnMouseEnter(
	MouseEventArgs e
)

Parameters

e
Type: System.Windows.Input.MouseEventArgs
The data for the event.

The OnMouseEnter method is called before any event handler for the MouseEnter event 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.

The RichTextBox implementation marks the MouseEnter event as handled by setting the Handled property of the event data to true.

Notes to Inheritors

When overriding the OnMouseEnter method in a derived class, be sure to call the base class’s OnMouseEnter method so that registered delegates receive the event.

Silverlight

Supported in: 5, 4

Silverlight for Windows Phone

For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
