DragDrop Class

Provides helper methods and fields for initiating drag-and-drop operations, including a method to begin a drag-and-drop operation, and facilities for adding and removing drag-and-drop related event handlers.

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

public static class DragDrop
You cannot directly create an instance of this class in XAML.

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
