How to create report parameter programmatically?

Hi,

I'm working on custom report manager. It manages "report entities" and

"report templates" (actually, RDLs uploaded on the server) and stores

one-to-many relation between them. The task is to store

"MasterEntityID" report parameter in every RDL and keep it up in actual

state whether RDL is being assigned to another entity or new RDL is

being uploaded and assigned. I've covered the first issue with

SetReportParameters() web method, but how should I deal with the second

one? Uploaded RDL may be short of the param, so I have to add it

programmatically while uploading.

Thanks,

AnatolyWhat exactly is the second issue? it looks like you have a custom application layer which can have complete control over the parameters.|||Yes, but actually I'm interested in adding new report parameter via web service. My application should do this if a developer of the uploading report hasn't defined necessary parameter manually. Is it possible?|||

The new parameter must be added to the report definition under the <ReportParameters> element. SetReportParameters won't let you configure the new parameter if it is not prior added to the report definition. This makes sense considering that you will probably need also to link the parameter to the report query. In fact, you won't need SetReportParameters for new parameters b/c once you add the parameter to RDL and call SetReportDefinition, the parameter will be created automatically for you.

As a side note, if you your application requires extensive reading/writing to RDL, you may benefit from buidling an object model on top of RDL that knows how to deserialize/serialize from/to RDL to avoid tedious XMLDOM programming and XPATH references.

Teo, thanks for your clear reply. I'd think of object model. Mostly because I'm going to generate some rdl templates (with datasources, datasets and queries definitions) programmatically in future.

Thank you once again and Happy New Year!)
