Question
Got a grid with some numeric columns and it's need to implement for each column an aggregate (sum or count) and display it under the corresponding column.
I know that some suites (DevExpress or other) had already implemented "by default". But there is a way to implement that using default controls or JVCL?
Solution
Since you have mentioned JEDI VCL
, try to take a look at the TJvDBGridFooter
component. It is the status bar for the TJvDBGrid
control.
- you can modify the displayed text in the
OnDisplayText
event - you can calculate the aggregate fields in the
OnCalculate
event - you can follow the grid column scroll, resize or modify the appearence of the panels
Check the demo projects from JVCL's ..\examples\JvUltimDBGrid
folder to see it in action.
