What you have to do is:

Add the following code inside Application_Start() in Global.asax:

 ClientDataTypeModelValidatorProvider.ResourceClassKey = "Messages";
 DefaultModelBinder.ResourceClassKey = "Messages";

Right click your ASP.NET MVC project in VS. Select Add => Add ASP.NET Folder => App_GlobalResources.

Add a .resx file called Messages.resx in that folder.

Add these string resources in the .resx file:

FieldMustBeDate        The field {0} must be a date.
FieldMustBeNumeric     The field {0} must be a number.
PropertyValueInvalid   The value '{0}' is not valid for {1}.
PropertyValueRequired  A value is required.

Change the FieldMustBeNumeric value as you want... :)

You're done.
