JQuery的，ASCX和webMethods不似乎是工作 [英] JQuery, ASCX and webmethods not seems to be working

问题描述

我有一个级联下拉（3人）类型，类别和子类别。类型的负载第一，在选择类型，类别负载和选择类别，子类别的负载。 另外我有2个按钮，添加目录和添加子类别当点击这些按钮，我叫一个jQuery模式窗体添加它们。我在code使用的WebMethod背后将它们添加到数据库

I have a cascading dropdown (3 of them) Type, Categories and Sub Categories. Type loads first and upon selection of Type, Category load and selection of Category, Sub Category loads. Also i have 2 buttons, "Add Category" and "Add Sub Category" Upon clicking on these buttons, i call a JQuery Modal Form to add them. I use Webmethod in code behind to add them to database

这完全在ASPX页面。

This works perfectly in ASPX page.

由于我需要使用3-4页，我认为进行上述的用户控件（ASCX）的。当我尝试使用此网页中，在ASCX的webMethods的不被调用。

Since I need use this in 3-4 pages, i thought of making the above as User control (ASCX). When i try to use this in a webpage, the webmethods in ASCX don't get called.

是我的做法是否正确？我应该为我的情况做

Is my approach correct? what should be done for my scenario

期待您的建议。

在此先感谢 KARTHIK

推荐答案

我不认为你可以有一个ascx控件内的WebMethod。 我解决它像这样我的问题：

i dont think you can have a WebMethod within a ASCX Control. I solved it for my Problem like this:

AJAXBridge：

AJAXBridge:

namespace Demo{
public partial class AjaxBridge : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    [WebMethod(EnableSession = true)]
    public static string Control_GetTest()
    {
        return Control.GetTest();
    }
}}

Control.ascx.cs

Control.ascx.cs

namespace Demo{
public partial class Control : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
    HttpContext.Current.Session["test"] = DateTime.Now.ToString();
    }

    // ALMOST A WEB METHOD
    public static string GetTest()
    {
        return " is " + HttpContext.Current.Session["test"];
    }
}}

Control.ascx

Control.ascx

<script type="text/javascript">    
var dataSend = {};

$.ajax({
    type: "POST",
    url: "AjaxBridge.aspx/Control_GetTest",
    data: dataSend,
    cache: false,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    beforeSend: function(data) {
        alert("before");
    },
    success: function(data) {
        alert("Page Load Time from Session " + data.d);
    },
    fail: function() {
        alert("fail");
    }
});    </script>

所以，你有一个ASPX其作用基本上像所有的AJAX方法对所有Web控件界面。此外，还有一些优势就像概述和所有外露的WebMethods的控制权，这使得它更容易处理安全性问题（例如，与注释）。

So you have one ASPX which acts basically like a Interface for all AJAX Methods in all your Web Controls. There also some advantages like having overview and control of all exposed WebMethods, which makes it a lot easier to handle security matters (eg. with Annotations).
