Visual Studio includes the Data Sources window, through which you can set up bindings not only to server-based data, but also to local data, Web services, and business objects. Dragging a table to a form creates a data-bound form, handling most of the steps that you had to complete manually in earlier versions.

The basic steps for creating an application such as this are as follows:

  1. Create a Windows Application project.

  2. Add a new data source.

  3. Select the display controls for table columns, or accept the default selections.

  4. Drag the table onto the form.

  5. Add the code for inserting, updating, and deleting records. Examine the code for the Click event of the Save item on the ToolStrip.
