XmlForm.Dirty property

Gets or sets a value that indicates whether the data in a form has been modified since it was last saved.

Namespace:  Microsoft.Office.InfoPath
Assembly:  Microsoft.Office.InfoPath (in Microsoft.Office.InfoPath.dll)

public abstract bool Dirty { get; set; }

Property value

Type: System.Boolean
true if the data in the form has been modified since it was last saved; otherwise false.

If the Dirty property is true, data in the form's underlying XML document has been changed since it was last saved. If false, no changes have occurred.

NoteNote

Changes that occur during a Loading event will not result in the Dirty property being set to true.

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.

In the following code example, the Dirty property of the XmlForm class is used to determine whether data in the form has been changed.

if (this.Dirty)
{
   MessageBox.Show("Data has been changed.");
}
else
{
   MessageBox.Show("Data has not been changed.");
}
