c# passing database and parameter to crystal report

Question

I get this error

The types of the parameter field and parameter field current values are not compatible.

when passing both database and parameter to Crystal Reports.

ReportDocument rd = new ReportDocument();

public string user;

public frmReport(string User)
{
        InitializeComponent();
        loadReport();
        this.user = User;
}

public void loadReport()
{
        rd.Load(@"C:\Users\Jeff Enad\Desktop\TEST1\Cebu Hallmark Hotel Management System\Cebu Hallmark Hotel Management System\cryReport.rpt");

        SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=dbCebuHallmark;Integrated Security=True");

        SqlDataAdapter da = new SqlDataAdapter("GetAllReport", con);
        rd.SetParameterValue("UserPrinted", user); //This is the parameter
        da.SelectCommand.CommandType = CommandType.StoredProcedure;

        DataSet ds = new System.Data.DataSet();
        da.Fill(ds, "REPORT");

        rd.SetDataSource(ds);

        crystalReportViewer1.ReportSource = rd;
        crystalReportViewer1.Refresh();
}

The SetParameterValue() is causing the error.

Can anyone help me to solve this problem? Should I add parameter in stored procedure or in dataset?

I just want to pass the user's name to the Crystal Report that has database.

You have to set the parameter and value in SqlCommand object in your SqlAdapter. Please see below for the updated code:

    public void loadReport()
    {
        rd.Load(@"C:\Users\Jeff Enad\Desktop\TEST1\Cebu Hallmark Hotel Management System\Cebu Hallmark Hotel Management System\cryReport.rpt");
        SqlConnection con = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=dbCebuHallmark;Integrated Security=True");
        SqlDataAdapter da = new SqlDataAdapter("GetAllReport", con);
        da.SelectCommand.CommandType = CommandType.StoredProcedure;
        DataSet ds = new System.Data.DataSet();
        da.Fill(ds, "REPORT");
        rd.SetDataSource(ds);
        rd.SetParameterValue("UserPrinted", user); //This is the parameter
        crystalReportViewer1.ReportSource = rd;
        crystalReportViewer1.Refresh();
    }
