问题 I am attempting to render a composite ProductCatalog view in ASP.NET MVC. This requires that I render multiple Product views per page. Each product view is a separate form. I need the form fields to have a prefix based on the id, so that I don't have duplicate IDs in the rendered document. Is there a way to define a prefix to be applied to all the form fields that are generated by the Html Extensions, or do I need to build this out manually? 回答1: Yes, you can define a prefix for the controls

问题 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

问题 Is there a good reason to use the strongly typed html helper... <%: Html.DisplayTextFor(model => model.Email) %> As opposed to... <%: Model.Email %> 回答1: Consider the following Model: public class MyModel { public string Name { get; set; } [DisplayFormat(NullDisplayText = "No value available!")] public string Email { get; set; } } in my view: <%= Html.DisplayTextFor(m => m.Email) %> <%: Model.Email %> The first line will display "No value available" if we leave the Email to be 'null' whereas

问题 I have a list of enums that I am using for a user management page. I'm using the new HtmlHelper in MVC 5.1 that allows me to create a dropdown list for Enum values. I now have a need to remove the Pending value from the list, this value will only ever be set programatically and should never be set by the user. Enum: public enum UserStatus { Pending = 0, Limited = 1, Active = 2 } View: @Html.EnumDropDownListFor(model => model.Status) Is there anyway, either overriding the current control, or

问题 Scenario Route: /template/customize/10 Where: 10 = ID of Template() In the controller the model is created based on the template so that the View's model is actually a Customization() object which actually has an Id of 0 because it's new. In the view I render @Html.HiddenFor( m => m.Id ) and the resulting value of that hidden input is 10 , though it should be 0 because m is of type Customization. I've run into this before with MVC 2 and worked around it by not using helper methods. Questions

问题 I want to create a custom actionlink but I don't know how to do this while fulfilling my needs. I worked with custom htmlhelpers before but this is a bit more tricky for me. The actionlink that I want to call needs to be like this: @Html.CustomActionLink("LinkText", "Area","Controller","TabMenu","Action",routeValues, htmlAttributes) so an example would be: @Html.CustomActionLink("Click here","Travel","Trip","Index","Index", new { par1 = "test", par2 = test2, new { @class = "font-color-blue" }
