Since view state data is stored in a page’s source code, large amounts of page data can overwhelm the memory of some mobile devices.

Since view state data is stored in a page’s source code, it can be accessed directly by viewing the page’s source code and can thus be tampered with.

Figure 16-1 shows an example of page values before and after a postback to the server that requests the same page. As can be seen in the first screenshot of the figure, selections have been made from the two drop-down lists, and entries have been made in the seven text boxes. The second screenshot shows the result of clicking the Save button, which requested a postback to the server requesting the same page. Notice that both drop-down list selections and all of the text box entries have been preserved and that no code was required to preserve this data.
