.NET Forum / ASP.NET / General / July 2007page_load fires with ajax call
i've got a script that takes about 10 seconds to complete with page_load. for that reason, i turned to ajax for additional dynamic updates i needed to do on the page without having to force the user through that 10 second delay, but it looks like page_load still gets called with an ajax submit. am i doing something wrong with my ajax calls or is this normal? tks Hello, yes Page_Load is fired on the server even when using AJAX as it is crucial part of the page lifecycle, one of the most important events. So if the logic is something that must be done, AJAX doesn't help with that since there's the initial loading of the Page anyway, and on async postback (ajax's post) that same logic would take 10 seconds too, your page just isn't halted for that 10 seconds, but you'd still need to wait 10 seconds to get the results back.E.g browser doesn't have to stop and wait. What you could do is that if you use ASP.NEt Ajax is that you can detect if you're in partial postback (ScriptManager.IsInAsyncPostBack http://www.asp.net/ajax/documentation/live/mref/P_System_Web_UI_ScriptManager_Is InAsyncPostBack.aspx), so that the logic isn't executed on the additional updates anymore (only on the initial load). Another way is to try to make the code execution parallel with the page execution by using asynchronous features of ASP.NEt 2.0 (http://msdn.microsoft.com/msdnmag/issues/05/10/WickedCode/#S2)  SignatureTeemu Keiski AspInsider, ASP.NET MVP http://blogs.aspadvice.com/joteke http://teemukeiski.net > i've got a script that takes about 10 seconds to complete with page_load. > for that reason, i turned to ajax for additional dynamic updates i needed [quoted text clipped - 3 lines] > > tks > Hello, > [quoted text clipped - 13 lines] > parallel with the page execution by using asynchronous features of ASP.NEt > 2.0 (http://msdn.microsoft.com/msdnmag/issues/05/10/WickedCode/#S2) thanks for the links, teemu. your first suggestion works great. >> i've got a script that takes about 10 seconds to complete with page_load. >> for that reason, i turned to ajax for additional dynamic updates i needed [quoted text clipped - 3 lines] >> >> tks It is normal.
