- An UpdatePanel cookbook
- UpdatePanel caveats and limitations
Using the UpdatePanel control can be a bit like using a Swiss Army knife. Most of the time, the primary utilities, such as the knife and scissors, are used to resolve issues. Other times, using additional functions and features of the tool make more sense when you’re attempting to solve complex problems. For example, it’s more feasible to use a screwdriver as opposed to the knife for a task such as tightening a screw. Knowing that these functions exist—and, just as important, how and when to use them—will make your use of the tool effective. The same notion is applied to the UpdatePanel: Understanding how to use its principal functions is only half the battle. Gaining a deeper knowledge of its capabilities and how it works will empower you to fully exploit its potential and take more control of your applications.
