The Value property of the UltraListViewItem and UltraListViewSubItem objects is of type object and can be set to any value; however, when the DataType property is set to a specific type, the result of an edit mode session is validated against this type. If the value entered by the end user is not valid for that data type, the UltraListView.EditError event is fired.
