Window.DragMove Method ()


Allows a window to be dragged by a mouse with its left button down over an exposed area of the window's client area.

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

public void DragMove()

Exception Condition

The left mouse button is not down.

The left mouse button must be down when DragMove is called. One way to detect when the left mouse button is pressed is to handle the MouseLeftButtonDown event.

When DragMove is called, the left mouse button must be depressed over an exposed area of the window's client area.


This method cannot be called when a window is hosted in a browser.

The following example shows how to override OnMouseLeftButtonDown to call DragMove.

protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)

    // Begin dragging the window
