I have aspx page with the code behind file.
In the aspx page i have some html content and java script.
I making a request to the aspx page in the page_load in the aspx i am doing some operation and returning the response as Response.Write("response string").
I observed that it's throwing error as invalid json and in the response body i total aspx content is getting added along with the response i want to throw.

Any idea what i am doing wrong?

What I have tried:

my Test.aspx.vb page
========================

VB

Partial Class HostBudget
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        result = singleCopy.ValidateTemp()
        Response.Write(JsonConvert.SerializeObject(result))
    End Sub
End Class

My Test.aspx page contains
Html content and javascript functions.

ASP.NET

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test.aspx.vb"
    Inherits="HostBudget" %>

<!DOCTYPE html>
<html>
<head  runat="server">
</head
<body></body></html>
<script>
Some js functions.
</script>

My ajax function call
========================

$.ajax({
      type: "GET",
      url: "../../HostBudget/Test.aspx,
      dataType: "json",
      success: function (response) {
          if (response.length > 0)
              alert(response)

      },
      error: function(XMLHttpRequest, textStatus, errorThrown) {
          CheckForAjaxError(XMLHttpRequest);
      }
  });

It's returning the response along with the aspx page content. error it's throwing as Invalid Json

Any idea what i am doing wrong?

You are calling Test.aspx and you are getting the page content. It seems like it is working correct. May be if that is not what you want, then change the URL to the correct one.

Before response.write where you return your json, call response.clear. Right now, your page returns full page (which is normal behaviour), you're just adding your json to the response. Clear will remove everything EXCEPT your json which you write after clear.

If you need the page to show AND to have json, you have to put json into script tag into previously defined javascript variable. Then you can access only that part without it being visible on the page.

From MSDN:
The Clear method erases any buffered HTML output. However, the Clear method erases only the response body; it does not erase response headers. You can use this method to handle error cases. Note that this method causes a run-time error if Response.Buffer has not been set to TRUE.
