QueryContinueDragEventHandler Delegate

Represents a method that will handle the routed events that enables a drag-and-drop operation to be canceled by the drag source, for example UIElement..::.QueryContinueDrag.

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

Syntax

Visual Basic

Public Delegate Sub QueryContinueDragEventHandler ( _
    sender As Object, _
    e As QueryContinueDragEventArgs _
)

public delegate void QueryContinueDragEventHandler(
    Object sender,
    QueryContinueDragEventArgs e
)

Visual C++

public delegate void QueryContinueDragEventHandler(
    Object^ sender, 
    QueryContinueDragEventArgs^ e
)

type QueryContinueDragEventHandler = 
    delegate of 
        sender:Object * 
        e:QueryContinueDragEventArgs -> unit

Parameters

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

e: Type: System.Windows..::.QueryContinueDragEventArgs
The event data.

Remarks

This delegate is used with the following attached events:

This delegate is also used with the following routed events on base elements. These routed events forward the previously listed attached events to make them more accessible to the general element model in WPF.

The attached events and the base element routed events share their event data, and the bubbling and tunneling versions of the routed events also share event data. This can affect the handled characteristics of the event as it travels the event route. For details, see Input Overview.

The DragDrop..::.QueryContinueDrag attached event occurs during a drag-and-drop operation and allows the drag source to determine whether the drag-and-drop operation should be canceled.
