Where's the beef?

rbuser

Actually I'm looking for the CreateAutoSearchField method. I have been using
it with TppReport compenents, but can't find it or a replacement for a
TrsClientReport component. How should I go about adding custom
AutoSearchFields?
Thanks,

Warren

AutoSearch works a little differently in a server environment. Custom search
fields need to be added by code that executes on the server side. The
Report.BeforeAutoSearchDialogCreate and OnGetAutoSearchValues events are
supported for server based reports.

The ClientReport retrieves the search parameters from the server, shows the
dialog and then sends the search values entered by the user back to the
server where they are used to generated the report.

Ok, I found that I can access the TppReport component through the
aEventParams that are passed to the ReportVolume, which gives me access to
CreateAutosearchCriteria and Create AutoSearchFields. Only questions now is
which ReportVolume event is best to use to use to Add my AutoSearch Fields.
It will be a hidden feied that the end-user does not need acces to. I
currently have the code in the OnGetReportParams event. Is this the best
place or is ther another event that would be better?
Thanks,

Rather than use the ReportVolume events, try using the
Report.BeforeAutoSearchDialogCreate event.

I don't see any Report.BeforeAutoSearchDialogCreate event anywhere on Client
or Server side. Where is it?

My response to the BeforeAutoSearchDialogCreate event question appears
below.

I reread your original question. And my question is how have you been using
CreateAutoSearchFields in your non server based reports. Perhaps if I
understand that better, we can more efficiently work towards implementing a
similar solution for the server environemnt. Are the reports form-based,
.rtm based, or stored in a database?

As described below you can use the ReportVolume.LoadReportEnd event to
initialize the report. That might be the place to add the AutoSearchFields.
The ClientReport will display the autosearch dialog by default, so you will
need to suppress it by using the ClientReport.OnReceiveAutoSearchFields
event to set ClientReport.ShowAutoSearchDialog to False.

The TppReport.BeforeAutoSearchDialogCreate event is an event associated with
the TppReport component. This event is available in all versions of RB, it
is not specific to the server.

To use this event in a server environment, you could implement the event in
RAP code - in which case the code is saved with the report definition. You
could implement the event in a form based reports. Or you can use the
ReportVolume.OnLoadEnd event to assign the event-handler programmatically.
The Sender of the OnLoadEnd event is the TppReport object.

example:

procedure TmyDataModule.rsReportTemplateVolume1LoadReportEnd(Sender:
TObject);
var
lReport: TppReport;
begin
lReport := TppReport(Sender);

{create autosearch fields here or attached the
BeforeAutoSearchDialogCreate event handler}


end;
