问题 In my Jquery script I post two doubles using the browser's CultureInfo (en-UK) that uses the . as a fraction separator.

问题 I have implemented an ajax-polling script that calls an action in the server Controller every 10 seconds. With the response, I replace the content of a div : function getFoo() { var link = '/Secure/GetFoo'; $.post(link, function (response) { $('#FooSection').replaceWith(response); }); setTimeout("getFoo();", 10000); } This is done through https .

问题 I use a DropDownListFor and a label text on my page. <%=Html.DropDownListFor(x => x.MotiveClientType, new SelectList( Model.ClientMotives, "Id", "Label", Model.MotiveClientType), new { id = "ddlMotiveClientType" } )%> How can I change my label when selecting value on my DropDownListFor ? 回答1: I'm not aware of any functionality native to ASP.NET MVC that will allow you to do this, but doing it with jQuery is a fairly trivial matter.

The web app has a complete layer built in to track this "if changed by user" thing. I was wondering if within ASP.NET MVC there is a provision/functionality to determine what property was changed by

问题 I want to know how to generate a pie chart dynamically. and how to redirect a page to another web page? 回答1: You could use Silverlight for the pie chart, it is very good for those and dynamic. for redirecting the page, if the page you want to redirect to is a View which is rendered by an action method, you can redirect to that action and it will redirect the page to its corresponding view after doing its magic: public ActionResult SomeAction(int id) { // Do your things here return

问题 I have an asp.net mvc 2 app, and I need to run a task (call WS, save into db) once a day. What is the suggested way for this? One thing, I have a feeling I would like to execute this task from within the webapp. Does anyone have any suggestions: I was considering .net quartz or regular System.Timers.Timer?

问题 I'm in the process of pulling a classic ASP app into Mvc2. I'll be deploying to an intranet and have been asked to enable support for Windows Authentication. The network I'll be deploying to has a few AD Domains and I'll only need to integrate with one in particular. Is it possible to use Windows Authentication and only allow authentication within a particular domain? Along those same lines, it's not uncommon for a user to have an account in multiple domains (the account names themselves are

问题 I've used the MVC pattern for a while now and have been getting on fine, however I've got totally stuck. I have a view which shows a collection of complex objects, with a partial view as follows: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ThreeSixtyScheduling.Areas.Products.Models.PartsOnOrderModel+PartOnOrder>" %> <tr> <% using (Html.BeginForm("UpdateStockDueDate", "PartsOnOrder", FormMethod.Post)) { %> <td><input type="hidden" name="CallAppointmentDate" value="<%=
