Exporting Crystal Report to PDF

[benwizzle]

I have a crystal report viewer bound as such:

ReportDocument rd = getReportDocument();

        
        
        DESClass des = new DESClass(key, iv);
        
        string encrypted;
        
        
        ParameterDiscreteValue crParameterDiscreteValue;

        ParameterFieldDefinitions crParameterFieldDefinitions;
    
        ParameterFieldDefinition crParameterFieldLocation; 
        
        ParameterValues crParameterValues;

        // Get the report parameters collection.
        crParameterFieldDefinitions = rd.DataDefinition.ParameterFields;

        // Add parameter value - SSN

        crParameterFieldLocation = crParameterFieldDefinitions["@SSN"];

        crParameterValues = crParameterFieldLocation.CurrentValues;

        crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();

        encrypted = des.Encrypt(txtSSN.Text);

        string script = "alert('" + encrypted + "');";

        ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "testing", script, true);

        crParameterDiscreteValue.Value = encrypted;

        crParameterValues.Add(crParameterDiscreteValue);

        crParameterFieldLocation.ApplyCurrentValues(crParameterValues);


        // Add parameter value @FromDate
        crParameterFieldLocation = crParameterFieldDefinitions["@FromDate"];

        crParameterValues = crParameterFieldLocation.CurrentValues;

        crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();

        crParameterDiscreteValue.Value = txtFromDate.Text;

        crParameterValues.Add(crParameterDiscreteValue);

        crParameterFieldLocation.ApplyCurrentValues(crParameterValues);


        // Add parameter value @ToDate
        crParameterFieldLocation = crParameterFieldDefinitions["@ToDate"];

        crParameterValues = crParameterFieldLocation.CurrentValues;

        crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();

        crParameterDiscreteValue.Value = txtToDate.Text;

        crParameterValues.Add(crParameterDiscreteValue);

        crParameterFieldLocation.ApplyCurrentValues(crParameterValues);


        // Add parameter value @Department
        crParameterFieldLocation = crParameterFieldDefinitions["@Department"];

        crParameterValues = crParameterFieldLocation.CurrentValues;

        crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();

        crParameterDiscreteValue.Value = txtDepartment.Text;

        crParameterValues.Add(crParameterDiscreteValue);

        crParameterFieldLocation.ApplyCurrentValues(crParameterValues);


        // Add parameter value @SSN
        crParameterFieldLocation = crParameterFieldDefinitions["@County"];

        crParameterValues = crParameterFieldLocation.CurrentValues;

        crParameterDiscreteValue = new CrystalDecisions.Shared.ParameterDiscreteValue();

        crParameterDiscreteValue.Value = txtCounty.Text;

        crParameterValues.Add(crParameterDiscreteValue);

        crParameterFieldLocation.ApplyCurrentValues(crParameterValues);
        
        //bind reportsource

        

        CrystalReportViewer1.ReportSource = rd;

When I bind the viewer programmaticall y the export button on the toolbar does nothing. It just reloads the page and the report disappears. In fact all of the buttons on the toolbar cause the page to reload and the report disappears.

So I am trying to make a button that will export the report to PDF format. The button looks like this:

// Get the report document
        ReportDocument repDoc = getReportDocument();

        MemoryStream oStream; // using System.IO
        oStream = (MemoryStream)repDoc.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
        Response.Clear();
        Response.Buffer = true;
        Response.ContentType = "application/pdf";
        Response.BinaryWrite(oStream.ToArray());
        Response.End();

Ive tried like 10 different ways I've found through google to export the report but they all give me the same errors. ExportToHttpRes ponse, ExportToDisk, and ExportToStream, all give me the same error.

The error always says Missing Parameter Values
The console says:
CrystalDecision s.CrystalReport s.Engine.Parame terFieldCurrent ValueException' occurred in CrystalDecision s.ReportAppServ er.DataSetConve rsion.dll

So yeah I just cannot find a way to export this thing...any suggestions would be appreciated
