title: Comma for thousands separator on a bound WebForms TextBox
body: <p>I'm trying to format a data bound value as below, but I keep getting a space as the thousands separator, i.e. the displayed text is always "12 340.00" when it should be "12,340.00".</p>
  
  <p>What am I missing?</p>
  
  <pre><code>&lt;asp:TextBox ID="budgetText" runat="server" Text='&lt;%# Bind("Budget", "{0:#,0.00}") %&gt;'&gt;&lt;/asp:TextBox&gt;
  </code></pre>
