Using Jquery and AJAX to pass parameters to VB.NET webmethod

由 江枫思渺然 提交于 2019-12-21 20:49:15
问题 I've been searching the internet for hours trying to pass parameters to my code behind using JQUERY $.ajax. I've tried a ton of different things, but nothing has worked. When I don't pass any parameters and set the vb.net function to not receive parameters the functions will get called. But once I try adding parameters, the function never gets called. Client Side: $("#<%=saveResource2.clientID %>").click(function() { var parDesc = $("#<%=ddlPDesc.clientID %> option:selected").text(); $("#<%

Should I be using Web API vs Web Methods?

由 大城市里の小女人 提交于 2019-12-21 09:15:22
问题 I'm trying to understand web api and some news about web methods. I've heard that we should stop using web methods from a few sources. Additionally, is Web API the successor if web methods should no longer be used? 回答1: Web methods are part of the ASMX technology. ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.

AJAX to web method not returning JSON

由 假如想象 提交于 2019-12-20 04:21:11
问题 I am calling a web method in aspx page from my js file using AJAX. I have set the method to be [WebMethod] and the page inherits from System.Web.Ui.Page class.

Why Can WebMethod Access Session State Without EnableSessionState?

由 北城余情 提交于 2019-12-19 12:55:00
问题 I have a method on a page marked as a [WebMethod] that uses some session state as part of its operation. After I wrote this code, I suddenly had a flash of memory that you need to use EnableSessionState when you use session state in a [WebMethod] (e.g. see here: http://msdn.microsoft.com/en-us/library/byxd99hx.aspx). But it seems to be working fine. Why? Sample code behind: protected void Page_Load(object sender, EventArgs args) { this.Session["variable"] = "hey there"; } [System.Web.Services

WebMethod in ASP.NET global error handler: how to trap values passed in AJAX POST request

由 ﹥＞﹥吖頭↗ 提交于 2019-12-19 11:27:54
问题 Stated another way, using HttpContext, how can I retrieve the parameters passed to a [WebMethod] when in a global error handler? Kovu gives a great example of how to do a global error trap to grab [WebMethod] errors in Global.asax, which I think he got from Richard Liu here, but his solution does not capture the parameters passed to the WebMethod, and I really need to log these to repro the errors. I adapted Richard/Kovu's example to start trapping more things about the request, but I just
