DragCompletedEventHandler

This DragCompleted event occurs when the left mouse button is released or when the CancelDrag method is called.

The Thumb control receives mouse capture when the user presses the left mouse button while pausing the mouse pointer over the Thumb control.

The position of the mouse when the DragCompleted event occurs is provided by the DragDeltaEventArgs of the last DragDelta event.

The following example shows how to assign an event handler for the DragCompleted event to a Thumb control, and how to define the event handler. For the complete sample, see Thumb Drag Functionality Sample.


<Thumb Name="myThumb" Canvas.Left="80" Canvas.Top="80" Background="Blue" 
      Width="20" Height="20" DragDelta="onDragDelta" 
      DragStarted="onDragStarted" DragCompleted="onDragCompleted"
      />



void onDragCompleted(object sender, DragCompletedEventArgs e)
{
    myThumb.Background = Brushes.Blue;
}
