The idea is that RateableWrapper is where most of our rate-list logic resides. It puts the rating bars on the rows, and it tracks the rating bars states as they are adjusted by the user. For the states, it has a float[] sized to fit the number of rows that the delegate says are in the list. RateableWrapper s implementation of getView() is reminiscent of the one from RateListDemo, except that rather than use LayoutInflater, we need to manually construct a LinearLayout to hold our RatingBar and the guts (a.k.a., whatever view the delegate created that we are decorating with the rating bar). LayoutInflater is designed to construct a View from raw widgets. In our case, we don t know in advance what the rows will look like, other than that we need to add a rating bar to them. However, the rest is similar to the one from RateListDemo, including using a ViewWrapper, hooking up onRatingBarChanged() to have the rating bar update the state, and so forth:

Clearly, picking the perfect regular expression may require some testing. In fact, numerous reference materials (on the Internet and in paper form) include useful regular expressions for validating common values such as postal codes. To experiment, you can use the simple RegularExpressionTest page included with the online samples, which is shown in Figure 8-5. It allows you to set a regular expression that will be used to validate a control. Then you can type in some sample values and see whether the regular expression validator succeeds or fails.

Figure 8-5. A regular expression test page The code is quite simple. The Set This Expression button assigns a new regular expression to the RegularExpressionValidator control (using whatever text you have typed). The Validate button simply triggers a postback, which causes ASP.NET to perform validation automatically. If an error message appears, validation has failed. Otherwise, it s successful.

Table 8-4 shows some of the fundamental regular expression building blocks. If you need to match a literal character with the same name as a special character, you generally precede it with a \ character. For example, \*hello\* matches *hello* in a string, because the special asterisk (*) character is preceded by a slash (\).
