Finding Component On Specific Page Of SubReport

rbuser

Hello

I have a Grid Pack DB Grid in my sub report. This grid is used to display
data and will be redrawn on each page until there is no more data.

I need to be able to find the grid that is displayed on the last page of the
report. When I can find this grid (not the 1 that is on the first page if
there is more than 1 page) I will then set some properties on the grid

Cheers

You might be able to check DataPipeline.Eof to try to determine when the
report is reaching the end.

Its difficult because the report does not know it is at the end until all
pages have been generated - so its a timing thing.

I suspect that the DataPipeline might work the same way. It does not know
its at the end until you try go forward and it cannot. Not sure about that
though.

I have a way of working out if I am on the last page of this report the
problem I have is that if I have a report with 3 pages there are 3 grids. I
want to modify the bottom row of the grid on page 3

Do you mean the report layout has 3 subreports?

The subreport.Report property provides access to the childreport. You could
iterate over the Report.Bands[].Objects[] structure. There is also a
FindUserObject method that you could call:

FindUserObject(aUserName: String): TppCommunicator

hi Nard

My Report has 1 subreport

In this sub report is a grid. When the grid fills a page the report goes
onto the next page. Its the final grid that I want to change

I use FindUserObject to get the grid but when I then make changes to the
object returned the grid on the first page is changed not the one on the
last page

You place one grid on your report/subreport, then there is one Grid object.


To conditionally change the properties of an object during report
generation, you will typically use the detailband BeforePrint event. (Or
perhaps the object's OnPrint event).

Have you tried that approach?
