CrystalReports print from DataSet - Problem

[lukasrzeznik]

I have problem with printing Crystalreports from Dataset as a source.

I have a Dataset fullfilled with data from query and CrystalRaports doesn't show
any data from dataset on the report.

Do you haeve any ideas what is the problem.

My Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Oracle.DataAccess.Client;

namespace PV_Report
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
              string sql = "select c782_storenr,c782_date,c782_pricefrom,c782_priceto,c782_moduser,c782_moddate from t782 "
                         +"where c782_storenr between 1000 and 9000 "   
                         +"and c782_date = to_date('2010-06-30','yyyy-mm-dd') "
                         +"order by c782_moddate, c782_storenr";
            
            string connsetting = "Data Source=xxxx;User Id=xxxx;Password=xxxx;";

          Daneset queryResult = new Daneset();

          OracleConnection connection = new OracleConnection(connsetting);
          connection.Open();

          OracleCommand command = new OracleCommand(sql, connection);
          command.CommandText = sql;
                        
          OracleDataAdapter adapter = new OracleDataAdapter();
          adapter.SelectCommand = command;
          adapter.Fill(queryResult,"tabledata");
          connection.Close();


          int temp = queryResult.Tables["tabledata"].Rows.Count;



          for (int i = 0; i < queryResult.Tables["tabledata"].Rows.Count; i++)
          {
              dataGridView1.Rows.Add();
              dataGridView1.Rows[i].Cells[0].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[0];
              dataGridView1.Rows[i].Cells[1].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[1];
              dataGridView1.Rows[i].Cells[2].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[2];
              dataGridView1.Rows[i].Cells[3].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[3];
              dataGridView1.Rows[i].Cells[4].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[4];
              dataGridView1.Rows[i].Cells[5].Value = queryResult.Tables["tabledata"].Rows[i].ItemArray[5];

          }

          CrystalReport1 cr = new CrystalReport1();
          cr.SetDataSource(queryResult.Tables["tabledata"]);
          cr.Refresh();

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

        }
    }
}

remove line#60 cr.Refresh(); it refreshes the crystal report write it before you set the datasource of crystal report

[abelLazm]

remove line#60 cr.Refresh(); and line#63 crystalReportViewer1.Refresh(); it refreshes the crystal report write it before you set the datasource of crystal report

[lukasrzeznik]

Doesn't work yet.

I see data in datagridview1 but CrystalReport is empty.

[kvprajapati]

Use crystalReportViewer1.RefreshReport() method instead of cr.Refresh() .

[lukasrzeznik]

It's works

That was the problem:

"...the names of the elements in this Dataset should be equal to the names of the elements in the DB..."
