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...
}

{

 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

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.
