How to URL encode parameters in ASP .NET MVC

由 为君一笑 提交于 2019-11-27 16:07:05
I have the following code in my view: <%= Html.ActionLink( "View item", "Index", "Items", new { itemName = Model.ItemName }, null) %> I have a problem when the item name contains a sharp (#) or the percent symbol (%). When the item name is "name#with#sharp#" , the controller receives only the first part of the name until the first sharp (only receives "name" ). When the item name is "name%with%percent" I get an error: HTTP error 400 - Bad request. I not sure if this is a problem with the URL encoding, because it works with other conflictive chars such as: ; = + , ~ [blank] Do you know how

JQuery DataTables .Net Server Side Pagination Issues

由 依然范特西╮ 提交于 2019-11-27 15:50:39
问题 I'm working on a bug fix right now for an application at work where the prior developer (since gone) didn't bother to paginate the data results on a page meant specifically for listing out data results. This of course has reared it's ugly head as users are starting to see long running script errors in IE. This, combined with the sheer data volume size, is making web pages nearly useless. Fast forward to my attempts to fix it and they've gone pretty well. The site is a .NET MVC 2 site that was

Host WCF in MVC2 Site

由 梦想与她 提交于 2019-11-27 15:49:37
We've got a very large, complex MVC2 website. We want to add an API for some internal tools and decided to use WCF. Ideally, we want MVC itself to host the WCF service. Reasons include: Although there's multiple tiers to the application, some functionality we'd like in the API requires the website itself (e.g. formatting emails). We use TFS to auto-build (continuous integration) and deploy - The less we need to modify the build and release mechanism the better We use the Unity container and Inversion of Control throughout the application. Being part of the Website would allow us to re-use

MVC 2 - Passing enum to CheckBoxFor

由 可紊 提交于 2019-11-27 15:12:26
问题 Let's assume we have a model: public class Document { public string Name { get; set;} public List<DayOfWeek> WeekDays { get; set; } } Is it possible to render checkboxes that represent days of week for that model? I've searched the internet but did not find any solution. I mean it works whith CheckBoxFor(model=> model.SomeProperty) but it does not work if SomeProperty is List<DayOfWeek> . DayOfWeek here is an enumeration. Thanks in advance. 回答1: You can enumerate on the values of the enum and

MVC 2 vs MVC 3 custom validation attributes using DataAnnotationsModelValidatorProvider.RegisterAdapter

由 自作多情 提交于 2019-11-27 14:45:36
问题 I read on some post, but cant find it now that in MVC 3 it was not really needed to create a Validator, only the Attribute. Is this true? I do say I find it confusing that the attribute has the IClientValidatable on it. So what does the DataAnnotationsModelValidator class do if the annotation has the client side script name (IClientValidatable), and the ability to validate (ValidationAttribute IsValid)? It would be really nice if I didnt have to register the Attribute with the Validator in

Set session variable in Application_BeginRequest

由 半世苍凉 提交于 2019-11-27 14:21:29
问题 I'm using ASP.NET MVC and I need to set a session variable at Application_BeginRequest . The problem is that at this point the object HttpContext.Current.Session is always null . protected void Application_BeginRequest(Object sender, EventArgs e) { if (HttpContext.Current.Session != null) { //this code is never executed, current session is always null HttpContext.Current.Session.Add("__MySessionVariable", new object()); } } 回答1: Try AcquireRequestState in Global.asax. Session is available in
