Description

DoLoadColumn is a method used to signal the OnLoadColumn event handler (when assigned) to load a column from an external XML configuration file. DoLoadColumn is called from the private LoadColumns method, and occurs immediately after a TColumn instance has been created, initialized, and added to the Columns collection.
