Examples
In the following example, the IsDOMReadOnly property of the XDocument object is used to determine whether data in the form's underlying XML document has been placed in a read-only state. If it has, a return statement is used to exit the event handler.
[InfoPathEventHandler(MatchPath="/my:myFields/my:field1", EventType=InfoPathEventType.OnAfterChange)]
public void field1_OnAfterChange(DataDOMEvent e)
{
// Determine whether the XML DOM is read-only.
if (thisXDocument.<span class="label">IsDOMReadOnly</span>)
return;
// Continue normal processing...
}

Remarks
If the IsDOMReadOnly property is true, data in the form's underlying XML document is in a read-only state and cannot be changed. If false, the data in the form's underlying XML document can be changed.
To determine whether the form has been placed in a read-only state, use the IsReadOnly property
The data in a form's XML document will be placed in a read-only state in the following scenarios:
- The form is digitally signed
- The form is in Reduced Functionality Mode (RFM) mode
- During an OnBeforeChange event
- During an OnValidate event
- During an undo or redo operation
