MVC3 Model validation not working on a double
I have a problem with yhe validation in MVC, my model has a double property and when I submit 10.30 or anything with "." inside it tells me that "The value '10.30' is not valid for Price". I did some research and they say that model valid开发者_运维技巧ation should be Culture invariant, I was thinking that it could be the problem since my browser and server is in french but it should'nt.
Here's my code :
[HttpPost]
[ValidateAntiForgeryToken]
[Authorize(Roles = "Admin")]
[ValidateInput(false)]
public virtual ActionResult Edit(AuctionModel model)
{
if (ModelState.IsValid)
{
//do the work
}
return View(model);
}
public class AuctionModel
{
public string Id { get; set; }
[Required(ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "FieldMandatory")]
[LocalizedDisplayName("Title")]
public string Title { get; set; }
[Required(ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "FieldMandatory")]
[LocalizedDisplayName("Description")]
public string Description { get; set; }
[Required(ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "FieldMandatory")]
[LocalizedDisplayName("Photo")]
public string Photo { get; set; }
[Required(ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "FieldMandatory")]
[LocalizedDisplayName("StartDate")]
public DateTime StartDate { get; set; }
[Required(ErrorMessageResourceType = typeof(Strings), ErrorMessageResourceName = "FieldMandatory")]
[LocalizedDisplayName("Price")]
public double Price { get; set; }
}
Thanks for the help!
Finaly I follow this post from Haacked :
http://haacked.com/archive/2011/03/19/fixing-binding-to-decimals.aspx
And it works like fine.
Here's the code :
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var valueResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
var modelState = new ModelState { Value = valueResult };
object actualValue = null;
try
{
actualValue = Convert.ToDecimal(valueResult.AttemptedValue, CultureInfo.InvariantCulture);
}
catch (FormatException e)
{
modelState.Errors.Add(e);
}
bindingContext.ModelState.Add(bindingContext.ModelName, modelState);
return actualValue;
}
And in the global.ascx :
ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());
Try to set the culture in OnActionExecuting.
btw I found another point.
public class CultureModelBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
System.Threading.Thread.CurrentThread.CurrentUICulture = yourCulture;
}
}
