get form query parameters values

Question

i am performing ajax call on my .aspx page

Passing some values which contain characters like '/' , '&' , '-' , '.' hence using encodeURIComponent

$('#divDialog').html('<p>Loading Please wait...</p>').dialog({ title: 'Processing Information', modal: true, resizable: false, draggable: false }).load('ajaxExecute.aspx?Fn=CAO2',
    {
        'EmploymentType': encodeURIComponent($('#cmbEmploymentType').val()), 'NatureIncome': encodeURIComponent($('#cmbIncomeNature').val())
    },
    function (response, status, xhr) {
        $('#divDialog').dialog('close');
        // Some Code
}
});

i am trying to get those values in c#

if (Request.Form["EmploymentType"] != "" && Request.Form["EmploymentType"] != null) string sEmpType = Convert.ToString(Request.Form["EmploymentType"]);

QuickWatch Shows values in Convert.ToString(Request.Form["EmploymentType"])

As Car%2FTruck%2FBoat%2FPlane%20Dealer

I tried HttpUtility.UrlEncode(Convert.ToString(Request.Form["EmploymentType"])) But Same result

How can i get string Car/Truck/Boat/Plane Dealer As it is in variable ?

@Dan-o used decode it works but not able to store value in variable. — Shaggy

You are using Request.Form, this will only work for from submits, not for ajax requests. Have a look at C# WebMethods they will turn the request data into C# objects for you. heres an example project

in ajaxExecute.aspx.cs:

 [WebMethod]
 public static void DoFoo(String EmploymentType, String NatureIncome){
     string sEmpType = EmploymentType;
 }

Javascript:

 $(...).load('ajaxExecute.aspx/DoFoo',
     {
        'EmploymentType' : $('#cmbEmploymentType').val(),
        'NatureIncome':  $('#cmbIncomeNature').val()
     }
     // rest of arguments
  }

this method will initiate auto. when this call ajaxExecute.aspx?Fn=CAO2 is made ?

You have to change it to call ajaxExecute.aspx/DoFoo

Done this but it coudnt able to hit break point on static method. It a Web Application ASP.NET & C#. Not a Web Service !! Will it Still Work ?

Yes you can add them directly to the ajaxExecute.aspx.cs file stackoverflow.com/questions/10688951/…
