问题 Currently working on a project in MVC-3. Trying to put the following code in my view, but Visual Studio is telling me it can't find the Serialize method. @Html.Serialize("User",Model) (ex) @using (Html.BeginForm()) { @Html.Serialize("User",Model) <fieldset> ... </fieldset> } Is this feature missing in MVC-3? I see examples of people using it in MVC-2. Perhaps there is a new way of handling this issue? 回答1: Html.Serialize is in the Futures assembly. 回答2: Install the Nuget package: Install

问题 How can i maintain scroll position on postback after sorting a grid table that uses MvcContrib framework? 回答1: The usual way is to use some javascript to set the current scroll position to a hidden field, then restore that position on page load (usually in a jquery ready event). However, that's really just a side effect. You should be doing some kind of ajax command to update the grid rather than a postback, then no scrolling required. 回答2: Use jQuery and client side cookie. $(function(){ var

问题 I am currently writing a small templating system in ASP.NET to allow users to add content. For example, the user can enter the string (variable type is string). topHeader[x] = "They think it's all over. It is now!"; However, one change that's needed is the ability to add some basic HTML tags within this content, so the following can be done topHeader[x] = "They think it's all over. <strong>It is now!</strong>"; or topHeader[x] = "They think it's all over. <a title="Football News" href="URL"

I want the top/default value to be 'Option1'. Enums: public enum EventType { [Display(Name = "Option 1")] Option1, [Display(Name = "Option 2")] Option2, [Display(Name = "Option 3")] Option3 } View: @Html.EnumDropDownListFor(model => model.EventType, null, new { @id = "eventType", @class = "form

问题 Using MVC 3 Razor, how can I specify a variable within a call to @Url.Content() . Example: @{ var myVar = Request.QueryString["foo"]; } <a href="@Url.Content("~/bar?@myvar")">click here</a> 回答1: You're already in the c# context at that point, so you can use the variable just like you would in a code file. Try this: <a href="@Url.Content("~/bar?" + myvar)">click here</a> 来源： https://stackoverflow.com/questions/6066002/how-to-include-an-mvc-razor-variable-within-url-content

问题 I'd like to be able to find out which C# version razor uses to compile my cshtml templates. The reason why I want this, is this breaking change. We had a lambda in a foreach statement that worked fine on our local dev machines but produced a bug on our test environment (which doesn't have C# 5 installed). This bug was VERY hard to debug (we even copied all the test environment DLLs and databases and were still not able to reproduce the bug). So to prevent this dev/test difference in the
