Step 1: Click New Project, then select Visual C# on the left, then Windows and then select Windows Forms Application. Name your project "DevReport" and then click OK
Step 2: Design your form as below
If you have not yet installed DevExpress .NET products, you can view How to download and install DevExpress
Your main form name: Form1

Your print form name: frmPrint

Step 3: Add a connection string to the App.config file
<connectionStrings>
<add name="cn" connectionString="Data Source=.;Initial Catalog=Northwind;User ID=sa;Password=123@qaz;" providerName="System.Data.SqlClient"/>
</connectionStrings>
We use the Northwind database to play demo. If you haven't got Northwind database, you can view How to download and restore Northwind database in SQL Server
Step 4: Install Dapper from nuget, then create Orders and OrderDetail class to map data return from the northwind database
public class Orders
{
public int OrderID { get; set; }
public string CustomerID { get; set; }
[Display(Name = "Contact Name")]
public string ContactName { get; set; }
public string Address { get; set; }
[Display(Name = "Postal Code")]
public string PostalCode { get; set; }
public string City { get; set; }
public string Phone { get; set; }
public DateTime OrderDate { get; set; }
}
public class OrderDetail
{
public int OrderID { get; set; }
[Display(Name = "Product Name")]
public string ProductName { get; set; }
public int Quantity { get; set; }
public decimal Discount { get; set; }
[Display(Name = "Unit Price")]
public decimal UnitPrice { get; set; }
public decimal Total
{
get
{
return Quantity * UnitPrice - Quantity * UnitPrice * Discount;
}
}
}
Step 5: Design your report as below

Step 6: Add code to handle your forms as below
frmPrint
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using DevExpress.XtraEditors;
namespace DevReport
{
public partial class frmPrint : DevExpress.XtraEditors.XtraForm
{
public frmPrint()
{
InitializeComponent();
}
public void PrintInvoice(Orders order, List<OrderDetail> data)
{
InvoiceReport report = new InvoiceReport();
//Hide paramater
foreach (DevExpress.XtraReports.Parameters.Parameter p in report.Parameters)
p.Visible = false;
//Init data report
report.InitData(order.OrderID.ToString(), order.OrderDate, order.ContactName, order.Address, order.PostalCode, order.City, order.Phone, data);
documentViewer1.DocumentSource = report;
report.CreateDocument();
}
}
}
Form1
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using Dapper;
using DevExpress.XtraEditors;
namespace DevReport
{
public partial class Form1 : XtraForm
{
public Form1()
{
InitializeComponent();
}
private void btnPrint_Click(object sender, EventArgs e)
{
Orders obj = ordersBindingSource.Current as Orders;
if (obj != null)
{
using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["cn"].ConnectionString))
{
if (db.State == ConnectionState.Closed)
db.Open();
//Execute query to get data from Orders and OrderDetails table
string query = "select d.OrderID, p.ProductName, d.Quantity, d.Discount, d.UnitPrice from [Order Details] d inner join Products p on d.ProductID = p.ProductID" +
$" where d.OrderID = '{obj.OrderID}'";
List<OrderDetail> list = db.Query<OrderDetail>(query, commandType: CommandType.Text).ToList();
//Open print form dialog
using (frmPrint frm = new frmPrint())
{
frm.PrintInvoice(obj, list);
frm.ShowDialog();
}
}
}
}
private void btnLoad_Click(object sender, EventArgs e)
{
using (IDbConnection db = new SqlConnection(ConfigurationManager.ConnectionStrings["cn"].ConnectionString))
{
if (db.State == ConnectionState.Closed)
db.Open();
//Excute query to get data from orders table
string query = "select o.OrderID, c.CustomerID, c.ContactName, c.Address, c.PostalCode, c.City, c.Phone, o.OrderDate" +
" from Orders o inner join Customers c on o.CustomerID = c.CustomerID" +
$" where o.OrderDate between convert(varchar(25),'{dtFromDate.EditValue}',103) and convert(varchar(25),'{dtToDate.EditValue}',103)";
ordersBindingSource.DataSource = db.Query<Orders>(query, commandType: CommandType.Text);
}
}
}
}
