Bind html Atrribute Doesn't work
<p>first example works. second fails misrebly why?</p>

<pre><code>(I except ErrorMessage="&lt;%# Model.StringProvider.GetString("Login.UserNameRequired.ErrorMessage")%&gt;")
</code></pre>

<p>to put the callled string in ErrorMessage this doesn't happen.</p>

<pre><code>&lt;asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName"&gt;&lt;%= Model.StringProvider.GetString("Login.UserNameLabel")%&gt;&lt;/asp:Label&gt;





&lt;asp:RequiredFieldValidator ID="UserNameRequired" runat="server" 
                                        ControlToValidate="UserName" ErrorMessage="&lt;%# Model.StringProvider.GetString("Login.UserNameRequired.ErrorMessage")%&gt;"
                                        ToolTip='&lt;%= Model.StringProvider.GetString("Login.UserNameRequired.ToolTip")%&gt;.' ValidationGroup="Login1"&gt;

                                        &lt;/asp:RequiredFieldValidator&gt;
</code></pre>

<p>both '' and "" don't work</p>
