TOraLoader.OnGetColumnData Event |

Occurs when it is needed to put column values.
property OnGetColumnData: TDPGetColumnDataEvent;
Write OnGetColumnData event handler to put column values. TOraLoader calls OnGetColumnData event handler for each column in the loop. Column points to TDAColumn object that corresponds to the current loading column. Use its Name or Index property to identify what column is loading. The Row parameter indicates the current loading record. TDALoader increments Row parameter when all the columns of the current record are loaded. The first row is 1. Set EOF to True to stop data loading. Fill Value parameter by column values. To start loading call the TDALoader.Load method.
Another way to load data is using OnPutData event.
