Property Value

Type	Description
String	A string representing the error description.

Remarks

You can use the ErrorText property to provide text explaining why validation failed. If the ValidateNodeEventArgs.Valid property gets set to false, this text will be displayed within a message box. Note that the text will be followed by the ‘Do you want to correct the value?’ string.

If handling the TreeList.InvalidNodeException event, you can modify the error message box’s text before it is displayed or prevent the message box from being displayed.
