asp.net mvc validation must be a number custom error

Question

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. B

Answer 1

This is the actual answer:

Create a class CustomClientDataTypeModelValidatorProvider. Copy the code from the MVC sources. Change the method MakeErrorString to output the appropiate message like this:

private static string MakeErrorString(string displayName)
{
    return string.Format(
        CultureInfo.CurrentCulture, 
        Core.Resources.Errors.EroareNuENr, 
        displayName);
}

I couldn't find a way not to copy the code just extend it as it uses this static method. If anyone knows this please tell me.

Then, in global.asax, I wrote this:

var cdProvider = ModelValidatorProviders.Providers.SingleOrDefault(p => p.GetType().Equals(typeof(ClientDataTypeModelValidatorProvider)));
            if(cdProvider != null)
            {
                ModelValidatorProviders.Providers.Remove(cdProvider);
                ModelValidatorProviders.Providers.Add(
                        new CustomClientDataTypeModelValidatorProvider());
            }

so that the flow would actually be routed to my class and not the class in the asp.net MVC dll

I got the idea from here:
