How to display data in crystal report using 2 sql request and 2 datatables in dataset?

Question

I have a dataset with 2 datatable aand I need to use 2 sql request to display data in crystal report. So I create 2 datatable in my dataset (DataTable1 and dataTable2) I tried t

Answer 1

the solution is to implement a Datatable Method for each DataTable used in the Dataset: example for the 1st Datatable:

protected DataTable DataTable1()
    {
        string sql = "MyRequest";
        SqlDataAdapter dad = new SqlDataAdapter(sql, con);
        DataSet1 ds = new DataSet1();
        dad.Fill(ds.Tables["NameOfDataTable"]);
        DataTable dt = ds.Tables["NameOfDataTable"];
        return dt;

    }

and in the print button you add this code:

try {
            DataSet ds = new DataSet();
            DataTable dt1 = DataTable1().Copy(); //the name of the method
            ds.Tables.Add(dt1);
            CrystalReport1 myreport = new CrystalReport1();
            myreport.SetDataSource(ds);
            crystalReportViewer1.ReportSource = myreport;

}
catch (Exception ex)
{
   //code ...
}

It works successfully :)
