Validate spaces using regular expression

I want to validate a field using regular expression as a data annotation. Suppose a user entered only spaces in a field need to alert a message something like "Spaces are not allowed". I'm using MVC4 and EF

[RegularExpression(@"^[\S]*$", ErrorMessage = "White space found")]

and then probably in the view you can alert the user.

If this is for an HTML form, you can use simple HTML.

<form onsubmit="alert('checked');return false;">
    <input required pattern=".*\S+.*" title="This field is required">
    <input type="submit" value="check" />
</form>
