Namespace: Microsoft.Office.InfoPath
Assembly: Microsoft.Office.InfoPath (in microsoft.office.infopath.dll)

Syntax

'Declaration
'Usage

Parameters

context
An XPathNavigator object positioned at the node that the error will be associated with.

name
The name of the error (cannot be blank).

message
The short message for the error.

messageDetails
The detailed message for the error.

errorCode
The error code of the error.

errorMode
An ErrorMode that specifies the mode for displaying the error message.

Return Value

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

Exceptions

Exception type	Condition
ArgumentException	The name is null or an empty string.
ArgumentException	An error of the same name already exists in the collection.
ArgumentNullException	The parameters passed to this method are null.
ArgumentException	The parameters passed to this method arenot valid. For example, they are of the wrong type or format.

Remarks

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

Note

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 Office InfoPath 2007 or in a Web browser.

Example

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, error number, and error display mode 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, ErrorMode.Modeless);

Dim root, txtbox As XPathNavigator
' Create XPathNavigator for main data source.
root = Me.MainDataSource.CreateNavigator()

' Create XPathNavigator positioned at field to add error.
txtbox = root.SelectSingleNode("//my:field1", Me.NamespaceManager)

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