label value dont save

[luis]

Hello .. I hope someone can help. I have a RadGrid on a Web Form with master page... i need to select a row and capture selected row index in a Label, to use this javascript code:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
    <script type="text/javascript">
        function RowSelected(sender, args) {
            document.getElementById("<%= Label1.ClientID  %>").innerHTML = args.get_itemIndexHierarchical();
        }
    </script>
  </telerik:RadCodeBlock>

At runtime, in the internet explorer, I can see that Label change to value of Row Selected ... for example: 2, 4, 7, 11 .
However, when I press a button the value of Labelxx.Text is ever "Label", the value really never change. I read many forums and posed a possible solution and that many people have worked is:

1) In the webform.aspx replace the code

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

by this

<asp:HiddenField ID="Label1" runat="server" />

2) replace the next line in javascript code:

document.getElementById("<%= Label1.ClientID  %>").innerHTML = args.get_itemIndexHierarchical();

by this

document.getElementById('Label1').value = args.get_itemIndexHierarchical();

3) in the Webform.aspx.cs take the value of label with:

string value_row = Label1.value

Curiosly .. this solucion works for me when the Webform.aspx isnot with the masterpage... When Webform.aspx is with MasterPage ... the same code is not working; I checked variables, codes, script and dont working ... nothing :'(

The MasterPage only contain a RadToolBar, a scriptManager and ContentPaceHolder... its all.
The WebForm only contain a RadGrid, native asp Label and native asp button...

 any idea why this happens? .. Thanks in advance for your help.
