How to allow only numbers in textbox in mvc4 razor

I have 3 text box which takes values postal code & mobile number & residential number. I got the solution for allowing only number in text box using jquery from Bellow post.

I would like to make an EditFor textbox accept numbers only

but can we do this using data annotations as I am using MVC4 razor ?


Solution 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

Solution 2:

Use a regular expression, e.g.

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

Solution 3:

@Html.TextBoxFor(m => m.PositiveNumber, 
                      new { @type = "number", @class = "span4", @min = "0" })

in MVC 5 with Razor you can add any html input attribute in the anonymous object as per above example to allow only positive numbers into the input field.
