Independence - layers are established so that if one is modified (to some extent) it will not affect other layers.

Now you can ask questions directly to me on my new site ASPForums.
With the use of Java Script alert we can display messages on different events in an ASP. The above will display the message correctly but the message will be displayed even before the page is loaded completely and will stop the execution until user closes the message box.In particular, we'll build an example that closely mimics the web-based email client user interface.Our example will include a paged Grid View listing the products in the database table with a checkbox in each row (see Figure 1).Free counters Added on January 19,2012 Follow Me @vmsdurano A bit About Me Disclaimer The opinions expressed herein are my own personal opinions and does not represent the opinions of my employers.Nor does it represent the opinion of my dog, because I don’t have one.
