procedure ApplyRange;
Description
After the range values are defined by using SetStartRange, SetEndRange, EditStartRange and EditEndRange methods, use ApplyRange to activate the defined range. When the range is active only records within a defined range are available to the application.
After a range is activated, the cursor is positioned on the first record in the range.
See TTable.ApplyRange for more details.
Example:
tab.EditRangeStart;
tab.FieldByName('ProdClass').AsString := 'FOTO';
tab.EditRangeEnd;
tab.FieldByName('ProdClass').AsString := 'FOTO';
tab.ApplyRange; apply the ranges - only FOTO products will be visible
