See you there.
Internet Explorer has supported disabling META REFRESH by domain since v6. The NoScript plugin for Firefox also provides an option to disable this tag. A better solution is to assume that script is disabled until you see the script-initiated request.
In fact, with script disabled, the UpdatePanel works even when EnablePartialRendering is true. The only problem is the number of intrinsic ASP.NET controls which only work if script is enabled - e.g. the LinkButton control.
hi Richard, good catch. Indeed you are absolutely right. That really slipped my mind. I have updated the code. Thanks!
So a solution off the top of my head would be to inherit these controls individually and perform this test for js from within their render method, in case of the LinkButton for example, that could be made to render an html input button instead. It is however a lot of work, but doable ofcourse.
A better approach again would be to try and make adapters for these controls, again that too has the work factor which is unavoidable. It's either that or wait for a future release of the .net framework that includes this type of rendering capability out of the box.
As currently i am working in a project where we are planning to use Ajax as client is expecting richer interaction.
Hi Om... it is possible in Firefox (I'm sure you can do it in other browsers)
(a) I don't see a querystring. Ever. Shouldn't that appear at least once?
Is this possible?
I am Sorry, the Above code is not working fine, if i disabled java script. one i disabled the java script and execute the same code in other window. then total page is posting to server. so, ajax is not working.
True, js is not essential but being able to degrade gracefully with minimum effort is equally important. noscript element won't get you very far on an ajax savy website. For instance take the updatepanel scenario that is able to degrade gracefully to full postbacks but needs to be enabled on the server. You end up not being able to reuse that feature with the noscript tag approach.
Having alternative code for every instance of dynamic js code you have on a page will soon get overwhelming in terms of development time and maintainence.
I prefer to tweak the current approach I've jotted here and fix the holes it has, as the one you pointed regarding people sharing the url. Unfortunately this is still an idea, and I've not had a chance to use in production code yet since disabling partial postbacks is only half the battle. You still need to fix instances of linkbuttons, dropdownlists with autopostback, textboxes with autopostback e.t.c
Thanks for pointing out the deficiency. Very much appreciated.
First of all ... sorry about my poor English grammar! ... and thanks dear Alessandro to share your great idea...
I can't imagine Web 2.0 without Frameworks, Libraries, Accordions, Tabs, Sliders, Multiple-level menus, Lightbox's, Carousel's, Form validators, animation effects and so on...
Your english is excellent. Thanks for the comment :-)
