MVC3有条件禁用Html.TextBoxFor（） [英] MVC3 Conditionally disable Html.TextBoxFor()

问题描述

我有一个C＃.NET Web应用程序。在该应用程序我需要根据谁登录有条件地禁止 Html.TextBoxFor 控件（也 Html.DropDownListFor 控件）到系统中。我试图用

I have a C# .Net web app. In that app I need to conditionally disable Html.TextBoxFor controls (also Html.DropDownListFor controls) based on who is logged into the system. I tried using

 @Html.TextBoxFor(model => model.ProposalName, new { @ViewBag.IsDisabled })

其中， @ ViewBag.IsDisabled 在控制器设置为的的String.Empty 或已禁用的。然而，这呈现为 IsDisabled =禁用或 IsDisabled =因此控制没有被禁用。当我试图

Where @ViewBag.IsDisabled is set to either String.Empty or "disabled" in the Controller. However, this renders as IsDisabled='disabled' or IsDisabled="" so the control is not disabled. When I tried

@Html.TextBoxFor(model => model.ProposalName, new { @ViewBag.Disabled })

控制总是禁用，即使 ViewBag.Disabled 不含文本。我怎么能有条件地禁用 Html.TextBoxFor（）控件？

The control was always disabled even if ViewBag.Disabled contained no text. How can I conditionally disable the Html.TextBoxFor() controls?

推荐答案

尝试

@Html.TextBoxFor(model => model.ProposalName, ViewBag.Disabled ? (object)new { disabled="disabled" } : new {})
