Examples

In the following example, the ReturnMessage property of the DataDOMEventObject object is used to display a message to the user if the data validation for the XML DOM node fails:

public void qtty_OnBeforeChange(DataDOMEvent e)
 {
  if (e.NewValue.ToString() == "")
  {
   e.<span class="label">ReturnMessage</span> = "You must supply a value for this field.";
   e.ReturnStatus = false;
   return;
  }
}

Remarks

Used in conjunction with the ReturnStatus property, the ReturnMessage property displays a message box to the user with the specified text message.
