Remarks

Creating custom code for pasting requires several steps:

  1. Set event.returnValue=false in the HTMLStyleElementEvents::onbeforepaste event to enable the Paste shortcut menu item.
  2. Cancel the default behavior of the client by including event.returnValue=false in the HTMLStyleElementEvents::onpaste event handler. This guideline applies only to objects, such as the text box, that have a defined default behavior.
  3. Specify a data format in which to paste the selection through the IHTMLDataTransfer::getData method of the clipboardData object.
  4. Invoke the IHTMLDataTransfer::getData method in the HTMLStyleElementEvents::onpaste event to execute custom code for pasting.
