Use this validation using regex.

[0-9][0-9][0-9][0-9]

Hi,
sorry for late reply.
You can use \s*[0-9]\s*[0-9]\s*[0-9]\s*[0-9]\s* expression for allow spaces.
try this link

you can also use this code and add only one or 2 line of code according to you requiremnest


XML
<script type ="text/javascript">
    function MaskMoney(evt)
    {
    if (!(evt.keyCode == 46 || (evt.keyCode >= 48 && evt.keyCode <= 57))) return false;
    var parts = evt.srcElement.value.split('.');
    if (parts.length > 4) return false;
    if (evt.keyCode == 46) return (parts.length == 1);
    if (parts[0].length >= 14) return false;
    if (parts.length == 4 && parts[1].length >= 4) return false;
    }
    </script>


In aspx.cs page
-----------------

 protected void Page_Load(object sender, EventArgs e)
        {
            TextBox1.Attributes.Add("onKeydown", "return MaskMoney(event)");
        }

You can use \s*[0-9]\s*[0-9]\s*[0-9]\s*[0-9]\s* expression for allow spaces.
