expression.IsNew
expression Required. An expression that returns a reference to an XDocument object.
2: Can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.
If the IsNew property is True, data in the form's underlying XML document has not been saved since the form was initially created. If False, the data in the new form's underlying XML document has been saved.
In the following example, the IsNew property of the XDocument object is used to determine whether the data in a new form has been saved:
if (XDocument.IsNew)
XDocument.UI.Alert("Please save your form.");
else
return;
