I would be much more usable to have a separate table for tooltips
I don't like to populate my working table with other columns only for a tooltip
It would be more comfortable to create a tooltip_table where you have 3 columns: id, table, column
so from the UI we can specify for the tooltip where to filter for the value.

You can use any field (e.g. the field itself) as Tooltip Field to enable tooltip for the field and use server event (e.g. Row_Rendered) to set your tooltip value from your own table, e.g.
$this->YourField->TooltipValue = ew_ExecuteScaler("SELECT tooltip FROM tooltip_table WHERE table = 'YourTable' AND column = 'YourField'"):
If you have many tooltip fields in the table, you can even get all the tooltip values for the table in, say, Page_Load events first so you don't need query database repeatedly.
