Occasionally, developers choose to disable this feature to prevent problems in a web farm where different servers have different keys (The problem occurs if the page is posted back and handled by a new server, which won t be able to verify the view state information) To disable hash codes, you can use the enableViewStateMac attribute of the <pages> element in the webconfig or machineconfig file, as shown here: <configuration> <systemweb> <pages enableViewStateMac="false" /> .. </systemweb> </configuration> However, a much better way to solve this problem is to configure multiple servers to use the same key, thereby removing any problem 9 describes this technique..

Figure 7-2 shows the preview page for a post that has not yet been published. Note that the buttons will not work until we implement the setstatus action.

Even when you use hash codes, the view state data will still be readable by the user. In many cases, this is completely acceptable after all, the view state tracks information that s often provided directly through other controls. However, if your view state contains some information you want to keep secret, you can enable view state encryption. You can turn on encryption for an individual page using the ViewStateEncryptionMode property of the Page directive: <%@Page ViewStateEncryptionMode="Always" %> Or you can set the same attribute in a configuration file: <configuration> <system.web> <pages viewStateEncryptionMode="Always" /> ... </system.web> </configuration> Either way, this enforces encryption. You have three choices for your view state encryption setting always encrypt (Always), never encrypt (Never), or encrypt only if a control specifically requests it (Auto). The default is Auto, which means that the page won t encrypt its view state unless a control on that page specifically requests it. (Technically, a control makes this request by calling the Page.RegisterRequiresViewStateEncryption() method.) If no control calls this method to indicate it has sensitive information, the view state is not encrypted, thereby saving the encryption overhead. On the other hand, a control doesn t have absolute power if it calls Page.RegisterRequiresViewStateEncryption() and the encryption mode is Never, the view state won t be encrypted.

Once the ItemTemplate has been processed, the Repeater will then output the SeparatorTemplate if one is present. In this case, you output a blue horizontal line: <SeparatorTemplate> <hr style="color:blue"/> </SeparatorTemplate> If a SeparatorTemplate isn t specified, nothing will be output, and the Repeater will immediately show the AlternatingItemTemplate. As you can see in Figure 7-2, the AlternatingItemTemplate is shown, not surprisingly, alternating with the ItemTemplate. If an AlternatingItemTemplate isn t specified, the ItemTemplate is simply repeated. The usual use of the AlternatingItemTemplate is to provide a quick means of showing alternating rows in a slightly different way. In this example, you ve simply changed the background color, as shown in Figure 7-4.

s Don t encrypt view state data if you don t need to do so. The encryption will impose a performance Tip

In Listings 7-23 and 7-24 we created a form to update the status of a blog post. We must now implement the controller action to handle the processing of this form. In addition to changing the status or deleting the post, we also added an option to edit posts. If the user clicks the edit button, we need to redirect them to the edit action we created earlier.

New C# programmers are sometimes intimidated by the quirky syntax of the language, which includes special characters such as semicolons (;), curly braces {}, and backward slashes (\). Fortunately, once you get accustomed to C#, these details will quickly melt into the background. In the following sections, you ll learn about four general principles you need to know about C# before you learn any other concepts.
