A reference to the new FormError that was added to the collection.

ExceptionCondition
ArgumentException

The name is a null reference (Nothing in Visual Basic) or an empty string.

ArgumentException

An error of the same name already exists in the collection.

ArgumentNullException

The parameters passed to this method are a null reference (Nothing in Visual Basic).

ArgumentException

The parameters passed to this method are not valid. For example, they are of the wrong type or format.

The FormErrorType of the new FormError will be set to UserDefined.

NoteNote

It is possible to add multiple errors with the same name parameter value to different context nodes. However, if you add an error with the same name to the same context node twice, the second error added overwrites the first one.

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.

This type or member can be accessed from code running in forms opened in Microsoft InfoPath Filler or in a Web browser.

In the following example, first an XPathNavigator object is positioned at the field with which to associate an error. Then, the XPathNavigator, name, message, detailed message, error code, and error number are passed to the Add method of the FormErrorCollection class to add the error to the form's error collection.

XPathNavigator root, txtbox;
// Create XPathNavigator for main data source.
root = this.MainDataSource.CreateNavigator();

// Create XPathNavigator positioned at field to associate with error.
txtbox = root.SelectSingleNode("//my:field1", this.NamespaceManager);

// Get form's collection of errors and add error.
this.Errors.Add(txtbox, "Field1Error", "Short error message.", 
   "Detailed error description.", 102057);
