FormError Class

Represents an error in the FormErrorCollection of a form.

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

Each FormError object in an InfoPath form is associated with a node in the form's underlying XML document. When data validation fails for a particular node, InfoPath creates a FormError object and places it in the FormErrorCollection associated with the form.

There are three types of data validation errors that can occur in an InfoPath form. They can be determined using the FormErrorType property of the FormError class:

  • FormErrorType.SchemaValidation   Data validation failed as a result of an XML Schema–defined constraint.

  • FormErrorType.SystemGenerated   Data validation failed as a result of constraints defined in the form definition (.xsf) file or as a result of form code calling the ReportError method of the XmlValidatingEventArgs class.

  • FormErrorType.UserDefined   Data validation failed as a result of a custom error defined using the Add method of the FormErrorsCollection class.

In the following example, clicking the Button control gets the first error in the FormErrorCollection of the form, and then displays the values of all of the properties of the FormError object.

public void ErrorBtn_Clicked(object sender, ClickedEventArgs e)
{
   FormError er = this.Errors[0];
   MessageBox.Show("Short message: " + er.Message);
   MessageBox.Show("Detailed message: " + er.DetailedMessage); 
   MessageBox.Show("Error code: " + er.ErrorCode);
   MessageBox.Show("Error name: " + er.Name);
   MessageBox.Show("Error type: " + er.FormErrorType.ToString());
   MessageBox.Show("Error site XML: " + er.Site.OuterXml.ToString());
}
