问题 I need to set the href attribute of a link to point to a specific image, which has its id from the database set as its title. However, I am having trouble with trying to format the string to include a call to get the title attribute of the image. Here is the base string: $("#favoriteLink").hover(function() { $(this).attr("href", '<%: Url.Action("FavoriteWallpaper", "Wallpaper", new{wallpaperId='+$(this).children.attr("title")+'}) %>'); }); favoriteLink is a div and the child is just one image

问题 I have a .NET 2.0 class the properties of which are marked virtual.I need to use the class as a model in a MVC2 application.

A snippet of what I have done is below // .NET 2.0 class public class Customer { private string _firstName = ""; public virtual string FirstName { get { return _firstName; } set { _firstName = value; } } } // .NET

问题 I don't really know where to look for an error... the situation: I have an ASPX view which contains a form and a few input's, and when I click the submit button everything is POST'ed to one of my ASP.NET MVC actions. When I set a breakpoint there, it is hit correctly. When I use FireBug to see what is sent to the action, I correctly see data1=abc&data2=something&data3=1234. However, nothing is arriving in my action method. ViewData is empty, there is no ViewData["data1"] or anything else that

问题 Per my previous question, I implemented a model binder that maps /api/v1/widgets/1,2,3 to // WidgetsController.cs: public ActionResult Show(IEnumerable<int> idArgs) { } This was working for a while, but now it is not any longer.

问题 I am using Membership.GetAllUsers() to get my user list. I would like to have the list returned sorted by email address as I need to flag some accounts with duplicate emails. Membership.GetAllUsers() seems to order by username by default. Is there a way to change this behavior? 回答1: If you can live with a generic list rather than a MembershipUserCollection : Membership.GetAllUsers().Cast<MembershipUser>().OrderBy(x => x.Email).ToList(); Use OrderBy(x => x.Email, StringComparer

问题 I beginners to the entity framework, so please bear with me... How can I relate two objects from different contexts together?
