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

Syntax

)

protected virtual void OnDragLeave(
    DragEventArgs e
)

Parameters

A DragEventArgs that contains the event data.

Remarks

The OnDragLeave method is called before any event handler for the DragLeave event is called. This method allows derived classes to handle the DragLeave 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 (the Handled property of the DragLeave event data.

Notes to Inheritors

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