Handsontable Grid - loading and saving data from aspx web page

问题

Is it possible to load and save data to/from a grid using c# code in the back from an aspx page, or does one have to use a web service (or PHP)? I have tried and failed using JSON.Net to map a very simple structure to code a backend structure

Is it possible to use JQuery (an ajax GET I presume) to make a call to a method in the backend code file (.aspx.cs)? I have tried using code from various posts on this forum, but there is little information on the backend code (c#), and all seem to refer to web services. Any help/advice would be much appreciated.

Here is the JavaScript code associated:

var handsontable = $container.data('handsontable');
$(document).find('button[name=load]').click(function () {
    $.ajax({
        url: "Default.aspx/getJSData",
        dataType: 'json',
        type: 'GET',
        //contentType: "application/json; charset=utf-8",
        success: function (res) {
            handsontable.loadData(res.data);
            $console.text('Data loaded');
        },
        error: function () {
            $console.text('Load error');
        }
    });

});

You still need to do an Ajax call but you don't need to do a web service (you can). The function you want exposed to the Ajax call put the [WebMethod] Attribute on and an use a Script Manager with the EnablePageMethods attribute set to true.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="True">
</asp:ScriptManager>

Method to Access:

[WebMethod]
public static void SomeFunction(string message, string name)
{

}

Ajax call using jQuery

(function($) {
        $.ajax({
            type: "POST",
            url: "test.aspx/SomeFunction",
            data: "{message:'Hello World', name: 'Bob'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (msg) {
                alert('success');
            }
        });
    });
