     In ASP.Net allow us to get information from the server without refreshing the entire page. This can come in very handy when you have large, graphic intensive, pages or if server side validation is needed for a field before submitting the entire page. Notice in my example how the model drop down list is repopulated every time the selected item in the Start With list is changed. The information for the State list is pulled from the server and the selected item in the State list is changed. The information for the District list is pulled from the server but notice how that list is the only item on the page to refresh. The rest of the page content is left in place that results in a much smoother user experience. It is also faster than refreshing the entire page as only the information for the list is sent back to the client instead of the entire page.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

If you don't have a virus scanner, you can get one at many places on the net including:McAfee.com
