If a form has been digitally signed, its underlying XML document is placed in a read-only state.

Security Level 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.

Example

In the following example, the IsSigned property of the XDocument object is used to determine whether a form has been digitally signed:

   XDocument.UI.Alert("This form contains digital signatures.");
else
   return;
