Is AJAX UpdatePanel dangerous for Login codes?

Question

4.67/5 (3 votes)

See more:

I am using a Modal popup extender of Ajax control toolkit for users to login to the site.

I have included the modalpopup in update panel. On clicking login button in the popup after entering username and password, the event is fired which has authentication code to retrieve the username and password and compare with that entered. And according to that, the user will be logged in or else nothing will happen.

I want to know whether I should use ajax for this authentication purpose or use complete postback without ajax???

I have this doubt as I have googled and found somewhere that updatepanels are dangerous.

Please help and guide me

:confused:

updatepanels are dangerous
Actually, update panel is easy to use and configure. You mentioned that you already goggled regarding this issue, so I think you acquired some basic information regarding update panel(disadvantage and advantage).

Well, if you can manage your problem using JQuery or any other client side scripting language that will be plus.

If i misunderstand, please feel free to correct me.

thnx for reply.

I want to know whether i can use login authentication code with ajax or not.

i.e. can I include authentication code in update panel or not.

I also found (while Googling) that while using update panels, the no. of bytes sent and received is much more than a web service or simple ajax.
check out the following links.
