问题描述

如何在mvc3的控制器中为@ html.textbox启用和禁用.

我的文本框代码:

 @ Html.TextBox("txtIden1")

谢谢.

解决方案

disable属性不是true \ false，但应该读为disable .... e.g

 @ Html.TextBox(" ，"  已禁用"})

您无需在控制器中进行设置，控制器负责将模型返回到指示应如何呈现的视图.因此，在您的控制器方法中

 // 您的模型
公共 类 SomeModel
{
    公共 字符串 SomeName { get ; 集;}
    公共 布尔 FieldIsDisabled { get ; 集;}
}

// 您的控制器操作
公共 ActionResult GetMyModel()
{
     var  model = 新 SomeModel
    {
        SomeName = " ，
        FieldIsDiabled =  true  // 实际上是确定逻辑这个... 
    }

   返回视图(模型)；
}

// 您的视图页面

@model SomeModel
@ {
    ViewBag.Title = " ;
}


@ Html.TextBoxFor(model = >  model.SomeName，model.FieldIsDiabled?( object )新 {disabled = " }:新 {})

How to give enable and disable for @html.textbox in controller in mvc3.

My textbox code:

@Html.TextBox("txtIden1")

Thanks.

解决方案

The disable property isn''t true \ false, but should just read as disabled....e.g

@Html.TextBox("txtIden1", new { disabled="disabled" })

You don''t set this in a controller, your controller is responsible for returning a model to the view that dictates how it should be rendered. So, in your controller method

// Your model
public class SomeModel 
{
    public string SomeName {get; set;}
    public bool FieldIsDisabled {get; set;}    
}

// Your controller action
public ActionResult GetMyModel()
{
    var model = new SomeModel
    {
        SomeName = "Test", 
        FieldIsDiabled = true // would actually be some logic to determine this...
    }

   return View(model);
}

// Your view page

@model SomeModel
@{
    ViewBag.Title = "Home Page";
}


@Html.TextBoxFor(model => model.SomeName, model.FieldIsDiabled ? (object)new { disabled="disabled" } : new {})
