To specify a different ordering, click the ORDER BY button.

Here you can choose what columns the data should be sorted by, and if it should be sorted in ascending or descending order.

However, the remaining screen shots are identical for both the Access Data Source and Sql Data Source. As you can see by the two radio buttons at the top of the screen you can either pick a table or view and select the columns to return (as shown in the screen shot below), or write a custom SQL statement or pick a stored procedure.

Also, we'll focus on working with these Data Source controls in Visual Studio 2005 through the Design view.

(True, you have to provide a connection string rather than simply the path to the file, but Visual Studio 2005 can automatically create appropriate connection strings for those databases residing in your folder.) In this article we'll examine the Sql Data Source in detail, just touching upon the one difference in the Access Data Source.
