Using JQuery.

$(document).ready(function()
 {
    //Only number and one dot
    function onlyDecimal(element, decimals)
    {
        $(element).keypress(function(event)
        {
            num = $(this).val() ;
            num = isNaN(num) || num === '' || num === null ? 0.00 : num ;
            if ((event.which != 46 || $(this).val().indexOf('.') != -1) && (event.which < 48 || event.which > 57))
            {
                event.preventDefault();

            }
            if($(this).val() == parseFloat(num).toFixed(decimals))
            {
                event.preventDefault();
            }
        });
    }

     onlyDecimal("#TextBox1", 3) ;



});
