Can I capture crystal report user input in my web application?

Question

Folks, I have a report that has a input paramter named "AccountKey". Crystal report launches its own input parameter capture screen where user can type in the AccountKey value and hit OK button. Subsequently the crystal report gets renedred in crystal report viewer.
I have a requirement of rendering the report in PDF not in crystal report. How do I do that.
I am able to do that when there is no user input needed in the crystal report or, if I can somehow supply needed input from code-behind, but the moment I has a parameter that expects user-input I loose control.
Is there anyway I can capture what value user has entered in Crystal Report Input paramagter capture form? or, any alternate that can help me acheive the result?
Thanks.

Hi,
To capture the values of Parameters the best thing you can do is to code for parameters and take values from it through text boxes, so that you can capture it.
here some sample code for it - try it
I would like you to know the following code that I have tried at my end using Viewer Object model:
// Object Declaration
ParameterFields boParameterFields = null;
ParameterField boParameterField = null;
ParameterValues boParameterValues = null;
ParameterDiscreteValue boParameterDiscreteValue = null;
ParameterRangeValue boParameterRangeValue = null;
// loading the report
CrystalReportViewer1.ReportSource = Server.MapPath("ReportWithSubReport.rpt");
CrystalReportViewer1.RefreshReport();
// passing database credentials...
foreach(CrystalDecisions.Shared.TableLogOnInfo boTableLogOnInfo in CrystalReportViewer1.LogOnInfo)
              ConnectionInfo boConnectionInfo = boTableLogOnInfo.ConnectionInfo;
              boConnectionInfo.UserID ="sa";
              boConnectionInfo.Password="sa";
// Parameter Country
boParameterFields = CrystalReportViewer1.ParameterFieldInfo;
boParameterField = boParameterFields["Country"];
boParameterValues = boParameterField.CurrentValues;
boParameterDiscreteValue = new ParameterDiscreteValue();
boParameterDiscreteValue.Value = "Argentina";
boParameterValues.Add(boParameterDiscreteValue);
// Parameter Sales
boParameterField = boParameterFields["Sales"];
boParameterValues = boParameterField.CurrentValues;
boParameterRangeValue = new ParameterRangeValue();
boParameterRangeValue.StartValue = 25000;
boParameterRangeValue.EndValue = 100000;
boParameterValues.Add(boParameterRangeValue);
// Parameter @percentage in subreport named SubReport
boParameterField = boParameterFields["@percentage", "SubReport"];
boParameterValues = boParameterField.CurrentValues;
boParameterValues.Clear();
boParameterDiscreteValue = new ParameterDiscreteValue();
boParameterDiscreteValue.Value = 75;
boParameterValues.Add(boParameterDiscreteValue);
Please note that I have used Range and Discrete values as parameter in the above code.
Also if you want to use the ReportDocument Object model then you can use:
ReportDocument.SetParameterValues("Parameter name", value)
Note:- This code is valid for only discrete values of Parameters.
or
boParameterFieldDefinitions = boReportDocument.DataDefinition.ParameterFields;
boParameterFieldDefinition = boParameterFieldDefinitions["@percentage","SubReport"];
boParameterValues = boParameterFieldDefinition.CurrentValues;
For getting output in PDF you can export the report to PDF throug viewer or from code fro e.g.-
boReportDocument.ExportToDisk(ExportFormatType.portabledocumentformat,"c:\\temp\\myrpt.pdf");
