Asp.net mvc 如何使用ViewBag或Model值在mvc中添加HtmlAttributes？

我有一个文本区域，在某些情况下可能要禁用它。我想将此信息作为ViewBag参数发送，但我不知道如何发送

我视图中的文本区域如下所示

@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", ViewBag.DisableProgressDetail })

在控制器中，我有如下内容：

if(conditions)
    ViewBag.DisableProgressDetail = "disabled=\"disabled\"";

// in the view:
@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", disabled=ViewBag.DisableProgressDetail })
-------------------------------------------------------------
// in the controller:
if(conditions)
    ViewBag.DisableProgressDetail = "disabled";
else
    ViewBag.DisableProgressDetail = "false";

// or more simply
ViewBag.DisableProgressDetail = (conditions) ? "disabled" : "false";

但是，html输出如下所示：

<textarea DisableProgressDetail="disabled=&quot;disabled&quot;" class="followUpProgress" cols="20" id="ProgressDetail" name="ProgressDetail" rows="2">
</textarea>

你想要的是：

@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", disabled = ViewBag.DisableProgressDetail })

然后在控制器中，只需将其设置为：

ViewBage.DisableProgressDetail = "disabled";

你想要的是：

@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", disabled = ViewBag.DisableProgressDetail })

然后在控制器中，只需将其设置为：

ViewBage.DisableProgressDetail = "disabled";

如果未指定属性，则该属性来自属性的名称，这就是为什么您会获得一个为ViewBag属性命名的html属性。让它工作的一种方法是：

// in the view:
@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", ViewBag.disabled })
-------------------------------------------------------------
// in the controller
ViewBag.disabled = "disabled";

如果您不喜欢这种方法，可以将禁用位设置为：

if(conditions)
    ViewBag.DisableProgressDetail = "disabled=\"disabled\"";

// in the view:
@Html.TextAreaFor(f => f.ProgressDetail, new { @class = "followUpProgress", disabled=ViewBag.DisableProgressDetail })
-------------------------------------------------------------
// in the controller:
if(conditions)
    ViewBag.DisableProgressDetail = "disabled";
else
    ViewBag.DisableProgressDetail = "false";

// or more simply
ViewBag.DisableProgressDetail = (conditions) ? "disabled" : "false";

它不起作用。您可以尝试以下方法：

//In the controller

if(Mycondition){ ViewBag.disabled = true;}
else { ViewBag.disabled = false;}

//In the view

@Html.TextBoxFor(model => model.MyProperty, ViewBag.disabled ? (object)new { @class = "MyClass", size = "20", maxlength = "20", disabled = "disabled" } : (object)new { @class = "MyClass", size = "20", maxlength = "20" })
