Hi parlardin,

I have tested using the latest version Q2 2013 and it seems to work the same for RadTextBox and Asp:TextBox.

Indeed the "   " is threaded as null, since the code of ASP Validator is like follows:

function ValidatorTrim(s) {
    var m = s.match(/^\s*(\S+(\s+\S+)*)\s*$/);
    return (m == null) ? "" : m[1];
}
function RequiredFieldValidatorEvaluateIsValid(val) {
    return (ValidatorTrim(ValidatorGetValue(val.controltovalidate)) != ValidatorTrim(val.initialvalue))
}

This means that string that does not contain characters different than space will considered as null.
