How to set currency format for textbox?
<p>I want enter numbers into textbox and textbox would convert automatically these number into currency.(12,345,654)</p>

<p>I can use FilteredTextBoxExtender </p>

<pre><code>&lt;ajaxToolkit:FilteredTextBoxExtender ID="ftbe" runat="server"
TargetControlID="TextBox3"         
FilterType="Custom, Numbers"
ValidChars="," /&gt;
</code></pre>

<p>But i want to  automatically add commas when user enters number.</p>
