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); } } } }
