How to Encode ASP.net Source Code ??

Hi All,

     I have a code block like the following. Well, I want to hide the content displayed  in "Intenet explorer >> View Source" for  <%Response.Write(mdata); %> .

The mdata contains pure html that will be rendered in to the aspx page.

            <table style="width:95%;margin-left:15px">
            <tr>
                <td>
                   <h3><asp:Label ID="Lbl_PHead" runat="server"></asp:Label></h3>
             &nbs ...
