title: asp.net mvc validation must be a number custom error
body: <p>I am new to asp.net and I have a problem. When the users insert in a editor for a decimal field something other than numbers, they get an error "Field name" is not a number. But I don't want them to receive this message I want them to receive another message. I have no problem with this with required and range validators.
  Is there any way for me to do this?</p>
  
  <p>I am not refering necessarily to changing the culture just displaying another message.</p>
  
  <p>Thanks.</p>
