Properties
Gets or sets the effects that the current handler can realize.
Remarks
Property Value
Gets the allowed effects for the current drag operation as specified by the DragSource.
Property Value
Gets or sets a value indicating whether this DragEventArgs has been handled.
Remarks
This property needs to be adjusted by handlers to tell the engine that the event has been handled.
Note that this property needs to be set before the function synchronously returns. This means that setting the value in an async function after the first await or in an asynchronous callback, it cannot not be seen by the emitter of the event and the sender will consider the event as not being handled.
// wrong:
mode.addEventListener('drag-enter', async (evt) => {
await something()
evt.handled = true // will be set *after* all other event listeners have been invoked, only
})
// correct:
mode.addEventListener('drag-enter', async (evt) => {
evt.handled = true // will be set immediately and 'mode' will see the change
await something()
})Property Value
true if handled; otherwise, false.Gets the data that is associated with the drag.
