Answer 1

i was just playing around with HTML5 input type=number. while its not supported by all browsers I expect it is the way going forward to handle type specific handling (number for ex). pretty simple to do with razor (ex is VB)

@Html.TextBoxFor(Function(model) model.Port, New With {.type = "number"}) 

and thanks to Lee Richardson, the c# way

@Html.TextBoxFor(i => i.Port, new { @type = "number" })  

beyond the scope of the question but you could do this same approach for any html5 input type

Use a regular expression, e.g.

[RegularExpression("([1-9][0-9]*)", ErrorMessage = "Count must be a natural number")] public int Count { get; set; }
