Examples

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

{
 thisXDocument.UI.Alert("This form contains digital signatures.");
}

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

if (thisXDocument.<span class="label">IsSigned</span>)
{

Remarks
