The attachment from is a compact ASP.NET/C# PayPal example that many found useful but incomplete for real projects. Several members asked how to use a SQL product table instead of the shipped XML () and others reported build errors because master/controls were missing (, , ). Below are practical, low-friction fixes: a simple Products schema, a safe ADO.NET pattern to load products, how to map results into the existing cart/session, and a quick way to restore missing master/control files so the solution will open.

Suggested Products table (simple, practical columns):

CREATE TABLE Products (
  ProductID INT IDENTITY(1,1) PRIMARY KEY,
  SKU NVARCHAR(50),
  Name NVARCHAR(200),
  Description NVARCHAR(1000),
  Price DECIMAL(18,2),
  StockQty INT,
  ImageUrl NVARCHAR(500),
  IsActive BIT
);

Minimal ADO.NET loader to replace the XML reader:

DataTable LoadProducts(string conn) {
  var dt = new DataTable();
  using(var cn = new SqlConnection(conn))
  using(var cmd = new SqlCommand("SELECT ProductID, Name, Price, ImageUrl FROM Products WHERE IsActive=1", cn))
  using(var da = new SqlDataAdapter(cmd)) { da.Fill(dt); }
  return dt;
}

Map rows into the cart the app expects (either a List<CartItem> or DataTable in Session). Create a small Product/CartItem DTO so existing cart logic sees the same properties (Id, Name, Price). offered help with this mapping—use that approach to keep the rest of the shopping/cart code intact.

Quick fix for "project could not be loaded" or missing Main.master.cs and controls/SideMenu.ascx: create placeholder files in the project folder and include them, or unload the project and edit the .csproj to remove bad paths. Minimal Main.master and SideMenu placeholders:

<%@ Master Language="C#" %>
<!DOCTYPE html>
<html><head runat="server"><title></title></head>
<body><form runat="server"><asp:ContentPlaceHolder ID="MainContent" runat="server" /></form></body>
</html>
<%@ Control Language="C#" %>
<ul><li><a href="/">Home</a></li></ul>

Notes: always test with PayPal Sandbox, validate IPN/PDT server-side (never trust client-side price), and use HTTPS for callbacks. If anyone still needs step-by-step edits to the original .csproj or mapping examples tied to the shipped code, and others here started that discussion and those specifics can be adapted quickly.

Hi Ceci, could you execute this app? asp controls are not included into the zip file.

Do you have them complete? could you send them to me, please?

I can help you accesing products from SQL Table if you still have that issue.

Thanks,
Danonegzz

Seems to be missing the following:


controls/SideMenu.ascx

Other that that it seems to be working (When you get build errors on compilation just click the 'Yes' button 'to continue and run the last successful build')

Hi,

I've downloaded the code but it gives error as "One or more projects in the solution could not be loaded". As said above, and controls/SideMenu.ascx files are missing. Can you please provide the these files?

Thanks,
SJ
