Passing parameters to crystal reports in C#

Question

I\'ve been trying to get this to work for a while, and all the example code I\'ve seen aren\'t quite doing what I\'m doing.

I have a program that returns a pdf of a

Answer 1

                rptTeacherTimeTable ttReport = new rptTeacherTimeTable();
                DataTable dt = new DataTable();
                dt = ObjclsT_TimeTable.GetTimeTableByClass(ClassID);

                objReport = ttReport;
                objReport.SetDataSource(dt);
                objReport.SetParameterValue("RTitle", "Class Time Table");
                objReport.SetParameterValue("STitle", "Teacher Time Table");
                reportViewer.crystalReportViewer1.ReportSource = objReport;
                reportViewer.crystalReportViewer1.Show();
                reportViewer.Show();

Answer 2

All that parameter code can be replaced with...

// Set datasource first
myDataReport.SetDataSource(...)
// Assign Paramters after set datasource
myDataReport.SetParameterValue("MyParameter", "Hello");

I can't remember if the order matters when setting the datasource and parameters. Maybe try setting the datasource first. The xsd/datasource has no relation to crystal parameters.

UPDATE1

SetParameterValue AFTER the datasource asignation or you will recieve error "Missing parameter values."

Answer 3

just do one thing and your code will run automatically set the data source first before adding parameters...

 crp rpt = new crp();
 rpt.SetDataSource(dt);
 rpt.SetParameterValue("p",p.ToString());

Answer 4

ReportDocument cryRpt = new ReportDocument();

TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();
Tables CrTables;

string path = "C:/reportpath/report.rpt";
cryRpt.Load(path);

cryRpt.SetParameterValue("MyDate2", str2);
cryRpt.SetParameterValue("MyDate", str1);

crConnectionInfo.ServerName = "server";
crConnectionInfo.DatabaseName = "DataBase";
crConnectionInfo.UserID = "user";
crConnectionInfo.Password = "password";

CrTables = cryRpt.Database.Tables;
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in CrTables)
{
    crtableLogoninfo = CrTable.LogOnInfo;
    crtableLogoninfo.ConnectionInfo = crConnectionInfo;
    CrTable.ApplyLogOnInfo(crtableLogoninfo);
}

crystalReportViewer1.ReportSource = cryRpt;
crystalReportViewer1.Refresh();

       //create object of crystal report.
        CrystalReport1 objRpt = new CrystalReport1();
        objRpt.SetDataSource(ds);
        ParameterFields pfield = new ParameterFields();
        ParameterField ptitle = new ParameterField();
        ParameterDiscreteValue pvalue = new ParameterDiscreteValue();
        ptitle.ParameterFieldName = "date";
        pvalue.Value = txtcolor.Text;
        ptitle.CurrentValues.Add(pvalue);
        pfield.Add(ptitle);
        crystalReportViewer1.ParameterFieldInfo = pfield;
        crystalReportViewer1.ReportSource = objRpt;
        crystalReportViewer1.Refresh();
