ASP.NET MVC Model Binder with Global Number Formats

Question

The default model binder is returning errors for properties that are of type double when my application is being used in countries that use different number formatting for d

Answer 1

Take a look in this article but, for short, if you could try this:

public ActionResult Create(FormCollection values)
{
    Recipe recipe = new Recipe();
    recipe.Name = values["Name"];      

    // ...

    return View();
}

...or this, in case you have a Model:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Create(Recipe newRecipe)
{            
    // ...

    return View();
}

The article has complete references and other ways of doing this. I use these 2 and they were enough for me up to now.

Answer 2

You want your application to use a single culture, right? If so, you can do this with the globalization tag of your web.config.

<configuration>
    <system.web>
        <globalization
           enableClientBasedCulture="true"        
           culture="en-GB"
           uiCulture="en-GB"/>
    </system.web>
</configuration>

And then you can forget those custom model binder and use the default.

UPDATE: Ok, it's a multi-language application. How do you get the culture you want? Can you call createCulture on the MvcApplication class? You could do this:

public class MvcApplication : HttpApplication
{
    //...
    public void Application_OnBeginRequest(object sender, EventArgs e)
    {
        CultureInfo culture = GetCulture();
        Thread.CurrentThread.CurrentCulture = culture;
        Thread.CurrentThread.CurrentUICulture = culture;
    }
    //...
}

This method is called before the model bind, so, again, you won't need the custom model binder. I hope it works for you :)
