Drag-and-drop functionality is designed to work both within an application and between applications. Dragging data between Windows Presentation Foundation (WPF) and non-WPF applications is also supported.

The following example demonstrates how to use a DragDrop object.

Private Sub DragStarted()
    m_IsDown = False

    Dim serializedObject As String = m_OriginalElement.OuterXml
    Dim data As DataObject = New DataObject()
    data.SetData(m_MyFormat.Name, serializedObject)
    Dim effects As DragDropEffects = _
        DragDrop.DoDragDrop(MyCanvas, data, DragDropEffects.Copy Or DragDropEffects.Move)
    If effects And DragDropEffects.Move Then
        ' Remove the element.
        m_OriginalElement.ParentNode.RemoveChild(m_OriginalElement)
        m_OriginalElement = Nothing
    End If
End Sub
