Radio Button generates duplicate HTML id-s

阅读更多关于 Radio Button generates duplicate HTML id-s

It seems that the default ASP.NET MVC2 Html helper generates duplicate HTML IDs when using code like this (EditorTemplates/UserType.ascx): <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<UserType>" %> <%: Html.RadioButton("", UserType.Primary, Model == UserType.Primary) %> <%: Html.RadioButton("", UserType.Standard, Model == UserType.Standard) %> <%: Html.RadioButton("", UserType.ReadOnly, Model == UserType.ReadOnly) %> The HTML it produces is: <input checked="checked" id="UserType" name="UserType" type="radio" value="Primary" /> <input id="UserType" name="UserType" type=

Using MVC's AuthorizeAttribute with multiple groups of Roles?

阅读更多关于 Using MVC's AuthorizeAttribute with multiple groups of Roles?

What I want to do is a two-level role check on an action handler. For example, Require that the users is in at least one of the following groups: SysAdmins, Managers AND in at least one of the following groups: HR, Payroll, Executive. Initial guess was that this might be the way to do this but I don't think it is: [Authorize(Role="SysAdmins,Managers")] [Authorize(Role="HR,Payroll,Executive")] public ActionResult SomeAction() { [...] } Do I need to role my own custom Attribute to take in Role1 and Role2 or something like that? Or is there an easier/better way to do this? You'll need your own

Render View programmatically into a string

阅读更多关于 Render View programmatically into a string

I would like to get the html code a view would generate in a string, modify it in my controller, then add it to my JsonResult. I found code that would do what i'm talking about from a partial. I would like to do it from an aspx View though. -- Extra explanation: Let's say I have a page Frame.aspx that /Controller/Frame will return I would like to get my hand on the response before it out so I can to wrap it with jsonp. I do not wish to edit the return result in code every time, this is why I want to load the view programmatically. /Controller/Frame currently returns Frame.aspx's content: <html

Validation messages are displayed when page load

阅读更多关于 Validation messages are displayed when page load

I have a problem with validation in ASP.NET MVC 2.0. I use the same Action in Controller to perform user request. For example: public ActionResult Index(ReportModel model) { if (!model.IsInitialDisplay && ModelState.IsValid) { model.Result = service.GetResult(model); } return View(model); } In the ReportModel, I define a flag IsInitialDisplay to determine whether the page is initial displayed or not: public class ReportModel { [Required(ErrorMessage = "*")] public string Criteria { get; set; } public bool IsInitialDisplay { get; set; } public ReportResult Result { get; set; } public

.NET 4 MVC 2 Validation with annotations warning instead of error

阅读更多关于 .NET 4 MVC 2 Validation with annotations warning instead of error

I am using .NET 4 with MVC 2 for validating with Annotations. Is there a (simple) solution for giving back a warning instead of the error ? So that I am able to get a green or yellow box with a message like "you should not use this content, but you may". Big thanks in advance! :) EDIT: Please observe that I am already able to throw out errors via ErrorMessage but I additionally want something like WarningMessage or InfoMessage so that the user only gets a warning but might proceed. Is there a solution for this? The Pseudocode would be: (Please note the "pseudo", because WarningMessage is

Foreach on IEnumerable property and CheckBoxFor in ASP.Net MVC

阅读更多关于 Foreach on IEnumerable property and CheckBoxFor in ASP.Net MVC

I believe this question applies to any of the "For" Html helpers, but my specific problem is using CheckBoxFor... I have a model that is of type IEnumerable, where rights is a simple POCO. This model is actually a property of a bigger model that I created an EditorTemplate for. Here is the bigger picture of my model: public class bigmodel { public string Title {get; set;} public string Description {get; set;} [UIHint("ListRights")] public IEnumerable<rights> Rights {get;set;} } public class rights { public bool HasAccess {get; set;} public string Description {get;set;} } I created an

阅读更多关于 ASP.NET MVC - Uploading an image to Amazon S3

I have my image from Request.Files[0]. Now, how do I upload this image to S3? I see that in the AWS .NET API you have to specify ContentBody when putting an object which is a string. How would I get the content body of my file? var file = Request.Files[0]; PutObjectRequest request = new PutObjectRequest(); request.BucketName = "mybucket" request.ContentType = contentType; request.Key = key; request.InputStream = file.InputStream; s3Client.PutObject(request); Slightly more detail with how to use folders and to grant all users read-only access.
