Michael, please clarify the task you're trying to accomplish by overriding the GetSelectionParams method. Making this method virtual is not a problem; however, due to its peculiarities first of all we'd like to examine your task to make certain that overriding the method is necessary.
Thanks,
Alex

Hi Alex
We introduced a new TableView event which indicates if a cell is enabled or not. Various factors can affect this at run-time. If a cell is NOT enabled, we change the colour of the cell to the disabled colour which indicates the cell cannot be edited.
This behaviour must override the built in styles.
Therefore, we override "GetDataCellContentParams" (and want to override "GetSelectionParams") to call our event and determine the enabled state before the style is set.
For example:
inherited;
AEnabled := <Call Event to determine enabled state based on ARecord and AItem)
if not AEnabled then AParams.Color := <UseDisabledColor>;
Regards
Michael
