Property Value
Type: System.Object
Remarks
The NewValue property contains the value of the XML DOM node that will replace the existing value. To get the original value of the XML DOM node, use the OldValue property.
Important
This member 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.
Examples
In the following example, the OldValue property of the DataDOMEventObject object is used to display the original value of an XML DOM node, along with its NewValue:
thisXDocument.UI.Alert("Original value: " + e.OldValue.ToString() + "\nNew value: " + e.NewValue.ToString());
In the following example, the NewValue property of the DataDOMEvent is checked for a blank value. If not blank, the "FirstName" and "Lastname" fields are cleared.
if (e.IsUndoRedo)
{
// An undo or redo operation has occurred and the DOM is read-only.
return;
}
// A field change has occurred and the DOM is writable. Write code here to respond
// to the changes.
if (e.NewValue.ToString() == "")
return;
