Control.OnDrop Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Called before the Drop event occurs.

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

Syntax

'Declaration
Protected Overridable Sub OnDrop ( _
    e As DragEventArgs _
)

protected virtual void OnDrop(
    DragEventArgs e
)

Parameters

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

Remarks

The OnDrop method is called before any event handler for the Drop event is called. This method allows derived classes to handle the Drop 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 Drop event data.

Notes to Inheritors

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