How to set footer/header in OnLoad event?

Applications Grid / Reports
#1

Hi, I want to show some information like totals, tips(such as how many work have done), it need to run a SQL and fetch records from table.

And now the header/footer of a Grid is set on the design-time.

Could I set the page header/footer on the OnLoad event, so I can finish some calculation?

Thanks.

use the onHeader or onFooter events. Runs whenever they are displayed.
