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
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.IsDOMReadOnly)
return;
// Continue normal processing...
}
