I have created a web page with with a report viewer that is suppose to get my data then show in the report viewer. Here is what I have tried below. I do not receive an error just not loading anything into the viewer. How can I fix this to display my data?

DataSet orderNumbers = new DataSet("OrderNumbers");
    SqlDataAdapter da = new SqlDataAdapter();
    SqlCommand cmd = new SqlCommand("SELECT WorkOrderNumber, LineNumber FROM WorkOrder WHERE WorkOrderNumber = " + workordernumberTextBox.Text);
    cmd.CommandType = CommandType.Text;
    cmd.Connection = new SqlConnection(ConfigurationManager.ConnectionStrings["LConnection"].ToString());
    da.SelectCommand = cmd;

    da.Fill(orderNumbers, "OrderNumbers");

    ReportViewer1.ProcessingMode = ProcessingMode.Local;
    ReportViewer1.LocalReport.DataSources.Clear();
    ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("OrderNumbers", orderNumbers.Tables[0]));
    ReportViewer1.LocalReport.Refresh();
