url parameters in asp.net webtier app

rbuser

l.s.

i am trying to pass a parameters thru the url to a report.
in the webtiercomserver i logged the contents of lParameters. It is filled
and passed to uWebTierModule.WebTier.ProcessWebRequest:

lwResponse := uWebTierModule.WebTier.ProcessWebRequest(lParameters, '');

In rsReportExplorerVolume1BeforePublishReport in dmvolume.pas of
Rboraclereportserver i tested
aEventParams.ReportParameters.Count and
aEventParams.sessionParameters.Count both are empty.

where and how can i access the parameters witch i passed to
uWebTierModule.WebTier.ProcessWebRequest?
i tried several things with your examples "customparameters" but i dont have
a form i want to access the report immediatly and pass an organisation id in
the url.

can you give me some hints?

thanx in advance

The RBServer\Demos\WebTier\CustomParameters demo shows how to do this. (You
need also run the RBServer\Demos\Server\CustomParameters server app).

Here is a brief overview:

1. Create a TrsWebRequest object. Pass the url parameters to the
constructor.

var
lWebRequest: TrsWebRequest;
begin

{use the incoming request parameters to create a TrsWebRequest}
lWebRequest := rsWebTier1.CreateWebRequest(Request.QueryFields,
Request.Content);

end;

2. See the online help topic for TrsWebRequest. Note that its
ContentParameters[] array property contains the url params received from the
web browser (i.e. the ones you passed in the constructor).

In your custom webtier logic you can read these parameters and use them to
populate the WebRequest SessionParameters[], ServiceParameters[], and
AutoSearchParameters[] arrays - which will be sent to the report server. The
ServiceParameters[] array property can be used for custom report parameters.
The SessionParameters[] array property can be used for custom session
parameters. There is also an AutoSearchParameters property.

3. The WebTier.ProcessWebRequest method is overloaded. You can pass it the
WebRequest object

myWebTier.ProcessWebRequest(myWebRequest);

Hi Nard,

thanx for the quick response: My problem is how to fit it in the
webtiercomserver.
It has a datamodule. The demo RBServer\Demos\Server\CustomParameters has
a webmodule.
So in webtiercomserver there is no action editor and i have no params like
Request.QueryFields and Request.Content.

For the WebTierComServer example, the TRBWebTier.ProcessWebRequest method is
being called rather than a web module action. The QueryString and
ContentString parameters are parsed into a Parameter list. You can pass this
list to the constructor of a WebRequest object.

function TRBWebTier.ProcessWebRequest(const QueryString,
ContentString: WideString): WideString;
begin

lParameters := TStringList.Create;

lsQueryString := QueryString;
lsContentString := ContentString;

TrsWebRequestParser.ParseContent(lsQueryString, lParameters);
TrsWebRequestParser.ParseContent(lsContentString, lParameters);

{******use the incoming request parameters to create a TrsWebRequest}
lWebRequest := rsWebTier1.CreateWebRequest(lParameters, nil);

{*****add logic here to read the webrequest.ContentParameters and populate
the webrequest SessionParameters and ServiceParameters }


lsResponse := uWebTierModule.WebTier.ProcessWebRequest(lWebRequest);

lwResponse := lsResponse;

Result := lwResponse;

finally
lParameters.Free;
end;



end;

Nard,

Thanx for your explanations,
i was totaly on the wrong track (read lost) working too complicated.
I added your code line:
lWebRequest := rsWebTier1.CreateWebRequest(lParameters, nil);
then added the parameter using
lWebRequest.SessionParameters.Add('onderdeel',value);
and that was all i needed.

thanx again for your input efforts
