Binding en-GB dates in a HTTP GET

Question

I\'m having a nightmare of a time with Dates. Were based in the UK, so our date format is dd/MM/yyyy. This is what users will type into the form when they want a certain dat

Got a solution, thanks to @Jon for the pointers:

public class GBDateModelBinder : IModelBinder
{

    #region IModelBinder Members

    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        string dateString = controllerContext.HttpContext.Request.QueryString[bindingContext.ModelName];
        if (string.IsNullOrEmpty(dateString))
                 dateString = controllerContext.HttpContext.Request.Form[bindingContext.ModelName];
        DateTime dt = new DateTime();
        bool success = DateTime.TryParse(dateString, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out dt);
        if (success)
        {
            return dt;
        }
        else
            {
            return null;
        }
    }

    #endregion
}

then register in global.asax:

ModelBinders.Binders.Add(typeof(DateTime), new GBDateModelBinder());

UPDATE

altered this to allow for the same issue when POSTing!

In addition to Liam's answer:

For those who are still having this issue (!) and are trying to bind to a Nullable DateTime, make sure you register the correct type in global.asax:

ModelBinders.Binders.Add(typeof(DateTime), new GBDateModelBinder());
ModelBinders.Binders.Add(typeof(DateTime?), new GBDateModelBinder());

Had me stumped for 15 minutes!
