如何在ASP.NET MVC中维护Html.CheckBox()的状态 [英] How to maintain state of Html.CheckBox() in ASP.NET MVC

问题描述

我的MVC应用程序中有两个复选框，它们都是布尔/位字段. "NotifyEmail"和"NotifySMS".

I have two checkboxes in my MVC app which are both boolean / bit fields. "NotifyEmail" & "NotifySMS".

每当我发回服务器并发生错误时，即使我设置尝试的值，复选框的状态也会消失.

Whenever I post back to the server and an error occurs, the state of the checkbox is gone event though I set attempted values.

推荐答案

<%=Html.CheckBox("AgreeToRules", (Request.Form["AgreeToRules"] ?? string.Empty).Contains("true"))%>
