    I am trying to make a jquery ajax call to one of the functions in my .cs file in webforms but the ajax call doesn't execute and in the dev tools i find 404 errors for MicrosoftAjax.js and MicrosoftAjaxWebForms.js. I have tried re-installing these packages into my solution but I still get those to errors. My solution also didn't have a route config which I added in. How do I resolve the 404 errors on the two ajax files which is why I suspect my ajax calls aren't working.

    Hi ShatterStar,

    It seems that you can't import js correctly.

    Have you tried adding ScriptManager control to the page:

    <head runat="server">
        <title></title>
    </head>
    <body>
    <form id="form1" runat="server">
        <div>
            <asp:ScriptManager runat="server"></asp:ScriptManager>
        </div>
    </form>
</body>

    Result:

    Or you could refer to some of the things done in How to Use CDN for MicrosoftAjax.js with ASP.NET Ajax 4 & Ajax Control Toolkit 40412.

    Hope this can help you.

    Best regards,

    Xudong Peng

    Hi ShatterStar,

    Using this control, it will import these two js files into the resource without manually importing them, as shown in my sample code.

    I want to know whether you have modified the BundleConfig.cs file in the App_Start folder?

    On the other hand, what method do you call using jquery ajax, WebMethod or other?

    If possible, please provide more details, mainly include:

    • .NET FrameWork version
    • Related sample code

    Best regards,

    Xudong Peng
