A common reaction to this advice (showing the user inputting text or other data into the UI as a controller) is that if it s implemented in the form of a web page, then you ll never actually write code to handle these events it s all done in the browser. The simple answer to this is that you re not actually designing at this stage. What you re primarily interested in with this diagram is showing everything from the use case text in picture form. Going to this level of detail might seem like a drag at first, but it s amazing how much hidden functionality gets uncovered this way. These details would have otherwise been left uncovered until after the software had been designed and coding had begun. In extreme cases, the details might not have been discovered until after the software shipped, the user did something unexpected, and the program crashed because the excruciating details hadn t been properly analyzed during robustness analysis. So, the lesson to learn from this is, if it s in the use case text, put it on the diagram!

Before you start using single-value data binding techniques in every aspect of your ASP .NET programs, you should consider some of the serious drawbacks this approach can present: Putting code into a page s user interface: One of ASP.NET s great advantages is that it finally allows developers to separate the user interface code (the HTML and control tags in the .aspx file) from the actual code used for data access and all other tasks (in the code-behind file). However, overenthusiastic use of single-value data binding can encourage you to disregard that distinction and start coding function calls and even operations into your page. If not carefully managed, this can lead to complete disorder.

Fixing one problem sometimes leads to the identification of another. After taking a thoughtful look at the two new controllers added in Figure 6-2, our reviewer spots another potential source of trouble.

Fragmenting code: When using data binding expressions, it may not be obvious to other developers where the functionality resides for different operations. This is particularly a problem if you blend both approaches for example, if you use data binding to fill a control and also modify it directly in code. Even worse, the data binding code may have certain dependencies that aren t immediately obvious. If the page code changes, or a variable or function is removed or renamed, the corresponding data binding expression could stop providing valid information without any explanation or even an obvious error. Of course, some developers love the flexibility of single-value data binding and use it to great effect, making the rest of their code more economical and streamlined. It s up to you to be aware of (and avoid) the potential drawbacks.

@Override public void onResume() { super.onResume(); registerReceiver(receiver, new IntentFilter(WeatherPlusService.BROADCAST_ACTION)); } @Override public void onPause() { super.onPause(); unregisterReceiver(receiver); }

Note In one case, single-value data binding is quite useful when building templates. Templates declare a block of HTML that s reused for each record in a table. However, they work only with certain rich data controls, such as the GridView. You ll learn more about this control in 15.

Reviewer: In the robustness diagram (see excerpt in Figure 6-3), you ve labeled the message between the actor (Customer) and the Write Review page boundary object.

If you decide not to use single-value data binding, you can accomplish the same thing using code. For example, you could use the following event handler to display the same output as the first label example:

Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As EventArgs) Handles Me.Load TransactionCount = 10 lblDynamic.Text = "There were " & TransactionCount.ToString() lblDynamic.Text &= "transactions today. " lblDynamic.Text &= "I see that you are using " & Request.Browser.Browser End Sub

In onResume(), we register a static BroadcastReceiver to receive Intents matching the action declared by the service. In onPause(), we disable that BroadcastReceiver, since we will not be receiving any such Intents while paused. The BroadcastReceiver, in turn, simply arranges to update the forecast:

This code dynamically fills in the label without using data binding. The trade-off is more code. Instead of importing ASP.NET code into the .aspx file, you end up doing the reverse: importing the user interface (the specific text) into your code file.
