How do I intercept the flow of data from Objective Grid to a database and vice-a-versa?

You have the option to override one of the following methods:

1. ConvertValueToString - Called from OnLoadCellStyle to retrieve a string with the value for the CDaoField bound to the specified column.  The string will be displayed in the grid.
   
   
2. OnLoadCellStyle - You might override OnLoadCellStyle if you want to specify the appearance of cells, like color, font etc.  This is most usefull if these settings depend on the current value as for example red for negative value.
   
   
3. OnFlushCell - Called to store the changed value into the recordset.
