问题 I have a LinkButton that I need to perform a click on to cause a postback. The actual link target is: javascript:__doPostBack('ctl00$c1$btnRefreshGrid',''); Clicking the link does perform the postback, as verified by a breakpoint in the code-behind. Also pasting javascript:__doPostBack('ctl00$c1$btnRefreshGrid','') in the address bar of the browser works with the same effect. I've tried the following with no effect at all: __doPostBack('ctl00$c1$btnRefreshGrid',''); $('#ctl00$c1

问题 Is it OK to use __doPostBack() or it is not recommended because it is generated from ASP.Net and we are not sure if they changed it in a next version of ASP.Net. 回答1: I would advice against it, since it's internal stuff of ASP.NET and was never meant to be used directly.

问题 Trying to automatically grab the search results from a public search, but running into some trouble. The URL is of the form http://www.website.com/search.aspx?keyword=#&&page=1&sort=Sorting As I click through the pages, after visiting this page, it changes slightly to http://www.website.com/search.aspx?keyword=#&&sort=Sorting&page=2 Problem being, if I then try to directly visit the second link without first visiting the first link, I am redirected to the first link.

问题 I have a really interesting problem. We have a site created with sharepoint 2013. We use Windows - NTLM authentication. In a page includes custom discussionListWebPart, we have a filter button which use javascript doPostBack function with webpart ClientID and filter parameters. exp: __doPostBack("ClientID","params"); When we do filter, just discussion list webpart do post back and no any request for the any part of Page.

问题 I'm trying to achieve a manual postback to trigger code not attached to a control. I don't want to use AJAX PageMethods as I need to reference certain controls during the postback, and want the result to update to a gridview on the page. I already have two other methods that work, but for some reason my third one doesn't once deployed, but does work fine on my dev machine. Code behind (Page_load) switch (Request["__EVENTARGUMENT"]) { case "ItemReserved": GetAllStock(); break; case
