DropdownList Linked to a Textbox

I am trying to display the selectedIndex of my dropdownlist in the textBox (field number 2) and in my ajax htmlEditor (field number 3). I already can show field number 1 on my dropdown, but I cant seem to show anything on the other boxes, all I get are errors :(, implying that the dataSource has not any items which is weird. Here are my classes.

Been checking this error all day long, with no plausible answer and can not detect what am I doing wrong.
Thanks for your assistance.

How to get a URL file name without extension in a webmethod

I have this URL (mydomain.com/mypage.aspx). I want to get the file name "mypage" only in a webmethod. I tried the following code but I only get the name of the function itself (MyMethod). I don't get the name of the page from the URL. Any help is well appreciated.
EDIT
To be more specific the webmethod resides in a user control so using FilePath OR PhysicalPath would give me the name of the UserControl file name (MyUserControl) and not the aspx page (mypage) in the URL.
mypage.aspx
<asp:Content ID="Content" ContentPlaceHolderID="ContentPlaceHolder" runat="server">
<uc:myUserControl runat="server" />
</asp:content>
myUserControl.cs
public static string PageName { get {
return (string)(Path.GetFileNameWithoutExtension(
Convert.ToString(HttpContext.Current.Request.Url)));
} }
OR
public static string PageName { get {
return (string)(Path.GetFileNameWithoutExtension(
HttpContext.Current.Request.RawUrl));
} }
OR
public static string PageName { get {
return (string)(Path.GetFileNameWithoutExtension(
HttpContext.Current.Request.PhysicalPath));
} }
[WebMethod]
public static string MyMethod()
{
StringBuilder SBstring = new StringBuilder();
SBstring.Append(PageName);
return SBstring.ToString();
}

Just use FilePath like this:
var fi = new FileInfo(HttpContext.Current.Request.FilePath);
var fileNameWithoutExtension = Path.GetFileNameWithoutExtension(fi.Name);

FileUpload Null reference error

I want to use FileUpload Control to save Image to Database. The HasFiles return always false after I click on BtnSave. I tried with and without UpdatePanel but could not find the solution.
My code is:
protected void BtnSave_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile == true)
{
var ChNumber = txtNumber.Text;
string img = this.FileUpload1.PostedFile.FileName;
//Save image to database function
}
else
{
lblStatus.Text="Image not Uploaded";
}
}

Try with a simple form without UpdatePanel. Here's the markup:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebForm1" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="BtnSave" runat="server" Text="Button" OnClick="BtnSave_Click" />
<asp:TextBox ID="txtNumber" runat="server"></asp:TextBox>
<asp:Label ID="lblStatus" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
</html>
And here's the code:
using System;
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void BtnSave_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile == true)
{
var ChNumber = txtNumber.Text;
string img = this.FileUpload1.PostedFile.FileName;
//Save image to database function
}
else
{
lblStatus.Text = "Image not Uploaded";
}
}
}
I set a brekapoint at if (FileUpload1.HasFile == true) and see the uploaded file is there.

Cannot Unregister UpdatePanel exception with Cross Page Posting

I am getting the dreaded exception "Cannot unregister UpdatePanel with ID 'UpdatePanel' since it was not registered with the ScriptManager" when trying to combine a popup window and some Cross-Page Posting. I've been able to reproduce the problem with a small example.
I have seen other questions that handle the Unload event for the UpdatePanel, but that doesn't seem to work with the addition of the Cross Page Posting.
How do I get around this issue?
To duplicate the issue with the code below:
Start the Setup page
Press the View Popup link
Close the popup
Press the Next button to transfer to the Target page
Press the Back button to transfer to the Setup page
Press the View link and close the popup
Press the Next button, and see the failure
Here are the highlights (forgive the length, but it should be cut-and-pastable):

As you can see, it's enough to have the UpdatePanel just sitting on the page and doing nothing for this error to occur.

My problem is that the parent checkbox ever is in false state in Checked property.
Also This page don`t perform correctly the validation actions. When i write in Firebug console validation asp function also return true state.
Which could be the problems?
Thanks in advance

Finally I use a simple html input tag for checkbox adding the onserverclick attribute.
Therefore not is necessary the autopostback.
Thanks and excuse me.
