Remarks
The HTMLMarqueeElementEvents2::ondragstart event is the first to fire when the user starts to drag the mouse. It is essential to every drag operation, yet is just one of several source events in the data transfer object model. Source events use the IHTMLDataTransfer::setData method of the dataTransfer object to provide information about data being transferred. Source events include HTMLMarqueeElementEvents2::ondragstart, HTMLMarqueeElementEvents2::ondrag, and HTMLMarqueeElementEvents2::ondragend.
When dragging anything other than an img object, some text to be dragged must be selected.
Calls the associated event handler.
To invoke this event, do one of the following:
- Drag the selected text or object.
