I created a crystal report and webpage , I want to open crystal report in my webpage depends on the textbox value and i need when click the button i send the values to crystal reports to show my crystal report . I tried the following code :

What I have tried:

protected void BtnCrystal_Click(object sender, EventArgs e)
        {
            if (Session["patientno"] != null && Convert.ToInt32(Session["patientno"]) > 0)
            {
              if (Convert.ToInt32(TXTDEPTID.Text) == 1 || Convert.ToInt32(TXTDEPTID.Text) == 2 )
                {
                  ReportDocument reportDocument1 = new ReportDocument();
                    reportDocument1.Load(Server.MapPath("~/RPT/RPT_CASH_RESULT.rpt"));

                    ParameterFields paramFields1 = new ParameterFields();

                    ParameterField paramField1 = new ParameterField();
                    ParameterDiscreteValue paramDiscreteValue1 = new ParameterDiscreteValue();

                    paramField1 = new ParameterField(); 
                    paramDiscreteValue1 = new ParameterDiscreteValue();  
                    paramField1.Name = "@ORDER_ID";
                    paramDiscreteValue1.Value = TXTORDERID.Text.ToString();
                    paramField1.CurrentValues.Add(paramDiscreteValue1);
                    paramFields1.Add(paramField1);

                    paramField1 = new ParameterField(); 
                    paramDiscreteValue1 = new ParameterDiscreteValue();  
                    paramField1.Name = "@deptid";
                    paramDiscreteValue1.Value = TXTDEPTID.Text.ToString();
                    paramField1.CurrentValues.Add(paramDiscreteValue1);
                    paramFields1.Add(paramField1);



                    CrystalReportViewer1.ParameterFieldInfo = paramFields1;
                    CrystalReportViewer1.ReuseParameterValuesOnRefresh = true;
                    CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;

                    CrystalReportViewer1.ReportSource = reportDocument1;
                    reportDocument1.SetDatabaseLogon("DB_admin", "1111");
                    }
                }


            }

You need to set the DataSource for the report Document.
You can see sample here ...

I changed the code but getting now new error :
protected void BtnCrystal_Click(object sender, EventArgs e)
{
if (Session["patientno"] != null && Convert.ToInt32(Session["patientno"]) > 0)
{

SqlCommand cmd = new SqlCommand("GET_ORDER_RESULT_PRINT_CASH", cn);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);

ReportDocument reportDocument1 = new ReportDocument();
reportDocument1.Load(Server.MapPath("~/RPT/RPT_CASH_RESULT.rpt"));
reportDocument1.SetDatabaseLogon("DBA", "1111");
reportDocument1.SetParameterValue("@ORDER_ID", TXTORDERID.Text);
reportDocument1.SetParameterValue("@deptid", TXTDEPTID.Text);

reportDocument1.SetDataSource(dt);
CrystalReportViewer1.ReportSource = reportDocument1;
CrystalReportViewer1.DataBind();

var connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "SQL";
connectionInfo.DatabaseName = "DB";
connectionInfo.Password = "1111";
connectionInfo.UserID = "DBA";
connectionInfo.Type = ConnectionInfoType.SQL;
connectionInfo.IntegratedSecurity = false;
for (int i = 0; i < CrystalReportViewer1.LogOnInfo.Count; i++)
{
CrystalReportViewer1.LogOnInfo[i].ConnectionInfo = connectionInfo;
}
}

when click the button its giving the following error now Additional information: Procedure or function 'GET_ORDER_RESULT_PRINT_CASH' expects parameter '@ORDER_ID', which was not supplied , I already added the parameters where is the error ?

Try removing the following lines, I don't think you need those

var connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "dba";
connectionInfo.DatabaseName = "DBA";
connectionInfo.Password = "DBA";
connectionInfo.UserID = "DBA";
connectionInfo.Type = ConnectionInfoType.SQL;
connectionInfo.IntegratedSecurity = false;
for (int i = 0; i < CrystalReportViewer1.LogOnInfo.Count; i++)
{
CrystalReportViewer1.LogOnInfo[i].ConnectionInfo = connectionInfo;
}

You need to add parameters to the SqlCommand not to the crystal report.

SqlCommand cmd = new SqlCommand("GET_ORDER_RESULT_PRINT_CASH", cn);
cmd.Parameters.AddWithValue("@ORDER_ID", TXTORDERID.Text);
cmd.Parameters.AddWithValue("@deptid", TXTDEPTID.Text);
SqlDataAdapter sda = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);

I tried this now no errors but when i click the button its not show the report :

SqlCommand cmd = new SqlCommand("GET_ORDER_RESULT_PRINT_CASH", cn);
cmd.Parameters.AddWithValue("@ORDER_ID",Convert.ToInt32(TXTORDERID.Text));
cmd.Parameters.AddWithValue("@deptid",Convert.ToInt32(TXTDEPTID.Text));
SqlDataAdapter sda = new SqlDataAdapter(cmd);
sda.SelectCommand.CommandType = CommandType.StoredProcedure;
DataTable dt = new DataTable();
sda.Fill(dt);

ReportDocument reportDocument1 = new ReportDocument();
reportDocument1.Load(Server.MapPath("~/RPT/RPT_CASH_RESULT.rpt"));
reportDocument1.SetDataSource(dt);
CrystalReportViewer1.ReportSource = reportDocument1;
var connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "dba";
connectionInfo.DatabaseName = "DBA";
connectionInfo.Password = "DBA";
connectionInfo.UserID = "DBA";
connectionInfo.Type = ConnectionInfoType.SQL;
connectionInfo.IntegratedSecurity = false;
for (int i = 0; i < CrystalReportViewer1.LogOnInfo.Count; i++)
{
CrystalReportViewer1.LogOnInfo[i].ConnectionInfo = connectionInfo;
}
