XmlValidatingEventArgs.ReportError Method (XPathNavigator, Boolean, String)

Creates a FormError object that contains custom error information with the specified values and adds it to the FormErrorCollection object of the form.

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

Parameters

node

An XPathNavigator positioned at the node that contains the data the error is associated with.

siteIndependent

Sets the condition for automatic deletion of the FormError object. If set to true, the FormError object will be deleted for changes to any nodes that match the XPath expression returned by the Match property of this event object. If set to false, the FormError object is deleted the next time the form is validated only when the node returned by the Site property of this event object has been changed.

message

The text to be used for the short error message.

Exception typeCondition

ArgumentException

The parameters passed to this method are not valid.

ArgumentNullException

The parameters passed to this method are null.

The ReportError method is used to create a custom error for an error that occurred during the Validating event.

When the ReportError method is called, InfoPath creates a FormError object and adds it to the FormErrorCollection of the current form. FormError objects are removed from the collection when the validation constraint is no longer invalid. In certain cases they can be explicitly removed using the Delete or DeleteAll methods.

FormError objects can also be created using the Add method of the FormErrorCollection class.

NoteNote:

Site-independent errors should be used when you want the errors to apply to all nodes of the same type. If you want the error to apply to a specific node, use site-dependent errors.

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.

In the following example, the Site property that the XmlValidatingEventArgs class inherits from the XmlEventArgs class is used to check the value of the node that raised the Validating event. If the data validation fails, the ReportError method is used to create a custom error.

public void field1_Validating(object sender, XmlValidatingEventArgs e)
{
   if (e.Site.InnerXml != String.Empty)
   {
      int fieldValue = int.Parse((e.Site.InnerXml));

      if (fieldValue > 50)
      {
         e.ReportError(e.Site,
            false,
            "Quantity cannot exceed 50.");
      }

      if (fieldValue < 0)
      {
         e.ReportError(e.Site,
            false,
            "Quantity cannot be less than 0.");
      }
   }
}
