ASP.NET MVC Razor View: The code block is missing a closing "}" character

by Oliver 13. June 2013 15:17

Some part of MVC 4 didn't like what was in my view: 1: @using Orchard.ContentManagement; 2: @using Orchard.Users.Models; 3: @{ 4: var userCanRegister = 5: @WorkContext.CurrentSite.As<RegistrationSettingsPart>().UsersCanRegister; 6: var enableLostPassword = 7: @WorkContext.CurrentSite.As<RegistrationSettingsPart>().EnableLostPassword; 8: } Turns out that the (incorrectly placed) @ signs in front of WorkContext were (finally) not swallowed silently anymore. Now, this works: 1: @using Orchard.ContentManagement; 2: @using Orchard.Users.Models; 3: @{ 4: var userCanRegister = 5: WorkContext.CurrentSite.As<RegistrationSettingsPart>().UsersCanRegister; 6: var enableLostPassword = 7: WorkContext.CurrentSite.As<RegistrationSettingsPart>().EnableLostPassword; 8: } It's just the error message that's a bit misleading.

Using @Html.CheckBox() with a dynamic value

by Oliver 19. November 2012 21:09

I’ve just spent much more time than I’d want on figuring out why the following code wouldn’t give me a checked checkbox, even when I set the ViewModel.Value to true: public class ViewModel { public string Name { get; set; } public dynamic Value { get; set; } } @Html.CheckBox(Model.Name, (bool?)Model.Value) The problem is with the signature of CheckBox, of course! Instead of calling the one where the second argument is of type bool, it calls the one where the second arg is of type object! // the method I thought I was calling public static MvcHtmlString CheckBox(this HtmlHelper htmlHelper, string name, bool isChecked) { return CheckBox(htmlHelper, name, isChecked, (object)null /* htmlAttributes */); }   // the method I in fact was calling public static MvcHtmlString CheckBox(this HtmlHelper htmlHelper, string name, object htmlAttributes) { return CheckBox(htmlHelper, name, HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes)); }   // the method that's being called by the second method above: isChecked == null! public static MvcHtmlString CheckBox(this HtmlHelper htmlHelper, string name, IDictionary<string, object> htmlAttributes) { return CheckBoxHelper(htmlHelper, null, name, null /* isChecked */, htmlAttributes); } Even though they were not strictly necessary, still, the framework sources helped me out this time to find this subtle bug (in my code, of course!). The solution to the problem looks like this: @Html.CheckBox(Model.Name, (bool)(Model.Value == true)) Happy Coding!
