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

问题描述

我有一个 C# .Net 网络应用程序.在该应用程序中，我需要根据登录到系统的人员有条件地禁用 Html.TextBoxFor 控件(也是 Html.DropDownListFor 控件).我尝试使用

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 在控制器中设置为 String.Empty 或 "disabled".但是，这呈现为 IsDisabled='disabled' 或 IsDisabled="" 因此控件未被禁用.当我尝试时

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 })

即使 ViewBag.Disabled 不包含任何文本，该控件也始终处于禁用状态.如何有条件地禁用 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

试试

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