问题 What is the best way to retrieve the display name attribute for an item in your model? I see a lot of people using the LabelFor helper for everything, but a label isn't appropriate if I just want to list the data out. Is there an easy way just get the Name Attribute if I just want to print it out in, say a paragraph? 回答1: <p> <%= Html.Encode( ModelMetadata.FromLambdaExpression<YourViewModel, string>( x => x.SomeProperty, ViewData).DisplayName ) %> <p> Obviously in order to avoid the spaghetti

问题 Does anybody know what's the difference between Html.RenderAction and Html.Action? 回答1: Html.Action() – Outputs string Html.RenderAction() – Renders directly to response stream If the action returns a large amount of HTML, then rendering directly to the response stream provides better performance than outputting a string. 回答2: The difference between the two is that Html.RenderAction will render the result directly to the Response (which is more efficient if the action returns a large amount

问题 I want to setup HtmlHelper::link() method so the default options array have escape = false. How can I achieve this without changing the core class? OBS: I already sanitized form input, so I guess this will have no problem.

问题 I'm new to nUnit and I've been tasked with creating unit tests for some htmlhelper extension methods. How should I go about creating a unit test for the following method? public static MvcHtmlString EnumDropDownListForOrderBy<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression, bool orderById, string firstElement = null, object htmlAttributes = null) { ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData); Type

问题 I found a few S.O. posts regarding this problem, but none of the accepted answers worked for me. I am using an enum to create an EnumDropDownListFor and it's working, but I do not want a blank entry at the top of the drop-down.

问题 I am using Java and HelpGUI in my OSGI bundle and the links that use do not work. When I use HelpGUI in a non-OSGI Java project, they work just fine on the same html files. Is there some security setting or something special with paths that I need to consider? Let me know, I am horribly stuck. 回答1: You should have a look at the source code of HelpGui, I can see why it doesn't quite work in OSGi (it relies on a specific URL format resources in jar files usually have).
