Application #47. Build Data-Entry Web Forms
Data entry in the form of a standard CRUD (Create, Read, Update, Delete) interface is an integral feature of many Web applications. This sample introduces you to ASP.NET and demonstrates how to build a data-entry Web form for products in the Northwind database. A DataGrid is used to display the products. Each row contains buttons to edit and delete the product. You can also click the Add New Item button located above the DataGrid. (See Figure 5-1.) Clicking the buttons to add or edit displays a simple entry form below the DataGrid.
