如何在RazorView中禁用动态设置Html.DropDownList属性? [英] how to Dynamic setting Html.DropDownList attribute disabled in RazorView?

问题描述

这是我的下拉菜单:

@Html.DropDownList("OptionType", selectList, new { @class = "form-control", name = "OptionType",@disabled = "disabled" })

上面的代码可以将DropDownList设置为禁用，但是我想使用模型中的bool值来动态设置Disabled属性.换句话说，如果bool value = true，则启用DropDownList，否则禁用DropDownList.如何实现?

The above code can set DropDownList is disabled，but I want to dynamic set disabled attribute with a bool value from model. In other words if bool value = true, DropDownList is enable, else DropDownList is disabled. how to achieve it?

推荐答案

如果要基于模型的属性禁用下拉列表，则:

If you want to disable the dropdown based on a property of your model:

@if(Model.DisableDropdown)
{ 
    @Html.DropDownList("OptionType", selectList, new { @disabled = "disabled", @class = "form-control" })
}
else
{
    @Html.DropDownList("OptionType", selectList, new { @class = "form-control" })
}
