Represents the method that will handle the DragStarted event of a Thumb.

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

Syntax

'Declaration
Public Delegate Sub DragStartedEventHandler ( _
    sender As Object, _
    e As DragStartedEventArgs _
)

public delegate void DragStartedEventHandler(
    Object sender,
    DragStartedEventArgs e
)

Parameters

  • sender
    Type: System.Object
    The object where the event handler is attached.

Remarks

When you create a DragStartedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events Overview for Silverlight.

You can also use the DragStartedEventHandler delegate combined with the DragStartedEventArgs class to provide drag started event data for custom controls that have drag events.
