Parser error when trying to generate gauge chart

Question

I'm trying to generate a gauge chart based on changing MTBF values, However when I run the webapplication, I get the error

Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: 'WebApplication1.WebForm3' is not allowed here because it does not extend class 'System.Web.UI.Page'.

Source Error:

Line 1:
Line 2: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication1.WebForm3" %> Line 3:
Line 4:

THe code that i have used is as follows,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication1
{
    public partial class WebApplication1 : System.Web.UI.Page
    {



        protected void Page_Load(object sender, EventArgs e)
        {



        }

        protected void Button1_Click(object sender, EventArgs e)
        {


            using (Testme entities = new Testme())
            {



                var execution = entities.TestExecutionDetails.Where(p => p.TestExecutionID == TestExecID).Select(p => p).OrderBy(p => p.StartTime).ToArray();
                var failures = entities.TestExecutionDetails.Select(p => p.Result != "Pass      ").Count();

                var uptime = entities.TestExecutionDetails.Where(p => p.Result == "Pass          ").Select(p => p);
                TimeSpan elapsedDuration = new TimeSpan(0);
                foreach (var p in uptime)
                {

                    elapsedDuration += (p.EndTime.Value - p.StartTime.Value);

                }
                var mtbfdisplay = elapsedDuration.TotalSeconds / failures;


                string str1 = @"

        data = google.visualization.arrayToDataTable([";

                string str2 = @"['Label', 'Value'],['MTBF'," + mtbfdisplay + @"],]);";

                string str3 = @"var options = {
                width: 400, height: 120, redFrom: 90, redTo: 100, yellowFrom: 75, yellowTo: 90, minorTicks: 5
            };


                var chart = new google.visualization.gauge(document.getelementbyid('chart-success'));
                chart.draw(data, options);";

                string postData = str1 + str2 + str3;

                Console.WriteLine(postData);


                ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "test", postData, true);

            }


        }
    }
}

The aspx code is as follows

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication1.WebForm3" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">

                <br />
    <div>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>

                <asp:HiddenField ID="HiddenField1" runat="server" Value="1" />
                <br />

                <asp:Label ID="Label1" runat="server" Text="1"></asp:Label>
                <br />

                <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

                <div id="chart-success"></div>

            </ContentTemplate>


        </asp:UpdatePanel>
    </div>


    </form>
</body>
</html>

I'm really stuck, I don't even know if this is the right approach to generate the charts, please help.

Thanks

Class WebForm3 is not declared anywhere (at least in the code that you have posted), so most likely this line:

public partial class WebApplication1 : System.Web.UI.Page

should be

public partial class WebForm3 : System.Web.UI.Page
