How do I pop up a dialog box in an InfoPath Web browser form?

If InfoPath forms that are enabled in browser-compatible mode are not able to pop-up dialogs directly using an ASP-like format, can we not just pop up the dialog box? The answer is certainly not.

We all know that the XmlFormView control is displayed in SharePoint hosted InfoPath form pages, and after reviewing MSDN, we find that we can add a "onnotifyhost" method to it, and then in the event we can register the JS popup dialog with code.

This time in the form can be called is very simple, this. NotifyHost ("MSG").

Enjoy SharePoint
