In the Components tray, open the smart tag for the ProductSubcategoryTableAdapter and click the Add Query link. After the click, the Search Criteria Builder dialog box opens. You must specify the syntax for a new query, and you must assign the new query a name (or you can use a previously specified query). The query name specifies a FillBy method that you can invoke with code for more customized solutions. However, the basic approach described here requires no code. In the current example, assign the name FillByCatID as the name of the query. The syntax for the query within the Search Criteria Builder dialog box appears in Figure 13-21. Figure 13-22 shows Form8 after it initially opens and after a value of 1 is entered as an @CatID parameter. The top view of Form8 shows the form when it opens. Notice that the BindingNavigator permits navigation to any one of 37 rows in the DataGridView control. This view of the data returned by the ProductSubcategoryTableAdapter includes no parameters. However, you can see the control for entering a parameter value above the BindingNavigator control. A TextBox is available for specifying an @CatID parameter value, and the text to the right of the TextBox can be clicked to invoke a parameter query that populates the DataGridView control with the results of the query. After entering a value of 1 for the parameter and clicking FillByCatID1, the DataGridView control displays just three rows. Each of these rows has a ProductCategoryID column value of 1. You can change the contents of the DataGridView control to display any other subset of rows based on ProductCategoryID column values by inputting a new value for @CatID and clicking FillByCatID1.

Note that Autofit modulates the column to make sure to reveal what is currently its widest entry, fitting itself snuggly to that entry s width; and so if you delete that item from the column and perform another Autofit, the column may narrow, as it hugs what is now the widest entry Now for an important variation on the Autofit theme, here s a scenario you might very well have to confront Suppose you ve entered the months of the year, and your data look like Figure 2 21:.

Nearly every web application nowadays requires user authentication of some sort, whether it's simply to change your e-mail address or manage your stock portfolio. Your application will be no different. You ll build out your authentication framework to let users enter and view timecard entries naturally, only for themselves. Authentication with App Engine comes in two flavors. You can choose to plug into Google s Accounts service (a.k.a Users service), or you can roll your own with custom classes, tables, and memcache. Developing your own authentication framework using memcache and sessions is fairly straightforward, but given the simplicity of Google Accounts, no one seems to do it. For most cases it just doesn t make sense to create a sign-up page, the ability to store user passwords, and add a forgot my password function, when you can use Google s code instead. You might want to make your own if you need to implement custom profiles and permissions, but typically you can just plug into Google Accounts and mark this requirement off your checklist. You ll get first-hand knowledge of the authentication functionality in Google Accounts because you ll be implementing this service for your application as well.

Figure 2 21. Columns in need of widening or narrowing The problem is clear: some of the longer month names have barged into the cells to their right, and these happen to be occupied by months of their own. Thus the same column-width issue emerges; but what s new here is that we can conduct an Autofit on several columns at the same time. To make this happen, click the first of the column headings A hold the mouse button down, and drag across the remaining headings (again, don t drag across row 1 on the worksheet; you need to select the headings). Your worksheet would look something like this, as shown in Figure 2 22:

You can readily extend the preceding example for parameter queries to all kinds of conditional, interactive displays. This section shows a simple extension that removes the need for a user to type in a number indicating the ProductCategoryID value for the list of product categories to show. Instead of typing in a number, a user can select from a list of product category names. After the selection of the name in one ListBox control, the application populates a second ListBox control with the product subcategory names from the currently selected category in the first ListBox control. In addition, the Click event procedure for a Button control changes the Items collection for the second ListBox to include all product subcategory names. Form9 in the WinCh13 project implements this solution.
