Remarks

The HTMLStyleElementEvents2::ondrop event fires before the HTMLStyleElementEvents2::ondragleave and HTMLStyleElementEvents2::ondragend events.

When scripting custom functionality, use the IHTMLEventObj::returnValue property to disable the default action.

You must cancel the default action for HTMLStyleElementEvents2::ondragenter and HTMLStyleElementEvents2::ondragover in order for HTMLStyleElementEvents2::ondrop to fire. In the case of a div, the default action is not to drop. This can be contrasted with the case of an input type=text element, where the default action is to drop. In order to allow a drag-and-drop action on a div, you must cancel the default action by specifying window.event.returnValue=false in both the HTMLStyleElementEvents2::ondragenter and HTMLStyleElementEvents2::ondragover event handlers. Only then will HTMLStyleElementEvents2::ondrop fire.

As of Microsoft Internet Explorer 5, drag-and-drop events can be used to carry out drag-and-drop activities, not only with input type=text elements, but also with block and inline tags. For example, text can be selected, dragged, then dropped on a div target. This causes several target events to fire, including HTMLStyleElementEvents2::ondragenter, HTMLStyleElementEvents2::ondragover, and HTMLStyleElementEvents2::ondrop. Because drag-and-drop actions are not directly supported on block and inline tags, you must use extra scripting to carry out the move or copy to the target using IHTMLElement::innerText, for example.

Calls the associated event handler.

To invoke this event, do one of the following:

  • Drag the selection over a valid drop target and release the mouse.
