Hi Alex,
Since you are using RadControls for ASP.NET Ajax, use the $find() method for getting the client side object of RadNumericTextBox. The document.getElementById will only return a client side reference to its input area DOM element. Try out the following code.

Hello Alex,
You can place the Javascript function provided by Shinu anywhere on the page that you prefer. However, if it is in the <head>, you must wrap the <script> tag with a <telerik:RadCodeBlock>, otherwise you will get a server error due to the code block.
<head>
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
// ....................
</script>
</telerik:RadCodeBlock>
</head>
