asp.net - Special Characters with Data Annotation MVC4 -

-

i have done validations using mvc4 data annotations.

and restricted special characters too.

but want allow spaces between each words.

i tried this:

[required(errormessage = "category name should not empty")] [regularexpression(@"^[a-za-z0-9]+$", errormessage = "special character should not entered")] public virtual string name { get; set; }

right system not allowing me insert. because have entered space. considering space special char.

how allow space? same time above validation should work.

myself found answer.

instead of @"^[a-za-z0-9]+$" need add @"^[a-za-z0-9'' ']+$".

''single space' in expression

'' '

for more information i'd suggesting reading - using data annotations customize data classes (msdn)
