The information you provide is accurate, and I got everything working, but the video is way too fast! It's like listening to that old FedEx ad where the guy was the world's fastest talker. Please slow it down so that the information doesn't fly past in a blur. I had to rewind about 10 times for each segment.

I have no doubt that you know this stuff, and you've nothing to prove to me. Just put it at a pace where we can follow. I don't think you'll use up an unnecessary amount of silicon.

Thanks,

Bill

Hello Sir,

Can we get a video from you wherein you demonstrate how to develop an entire application using Ajax. This will help us to an get an idea about the 'must know features' of ajax required in every application.You may also take up parts of an application like shopping cart, user registration etc to show how ajax can be used in them.

Thanks .

I can understand that in the following situation all the three text boxes will be update on Button1.Click

TextBox1 is outside of UpdatePanel1

TextBox2 is inside UpdatePanel1

TextBox3 outside of UpdatePanel1

Button1 is outside of UpdatePanel1

UpdatePanel1 is not wired to Button1.Click

Make the following change and run the application to notice that only TextBox2 is update.

UpdatePanel1 is wired to Button1.Click by triggers

Please bear with my dumb question: But I would like to learn in detail - What stopped other two text boxes from getting updated?

Bill - sorry you found the pace too fact, most of the feedback I get indicates that folks prefer the crisp pace to a slower one. Feel free to meial me if you get stuck on anything that I might be able to help with.

Sunil - The ones outside the update panels are not updated because they are outside th eupdate panels.

UpdatePanel2 is not updated because Button1 is a trigger to UpdatePanel1 but not UpdatePanel2 and UpdatePanel2 has UpdateMode set to contidional=true.

Feel free to email me through my blog's contact l;ink at www.joeon.net

is there a way to use the update panel on a textbox that is triggered by a Javascript onblur function?
