I am currently working on an Webservice to retrieve a pdf Document from an Crystal Report. As lonmg as there are no parameter Values in the Report, the service works fine. As soon as I use parameters in a Query the Reports can’t be shown anymore and I retrieve an error like ‘missing parameter values’. But there is only one Parameter and I am pretty sure that I set the value of that parameter… Here is the Code where I change/ add the value:

 // param is a string like 'parametername:value' string index = param.Split(':')[0]; string value = param.Split(':')[1]; // repDoc is the current Report repDoc.ParameterFields[index].CurrentValues.Clear(); repDoc.ParameterFields[index].CurrentValues.AddValue(value); // now i create the PDF as an HTTPresponse repDoc.ExportToHttpResponse(ExportFormatType.PortableDocFormat, response, false, 'Report');

I really have no idea why it doesnt work…

  1. I have found the mistake… I did a repDoc.refresh() before I created the Report.. seems like the Parameter Values are dropped that way… after removing the Refresh everything works fine 🙂

    thx for the help!!!
