asp.net-mvc-3 - 如何根据对象值选择 Html.Radiobutton

Question

我的 asp.net mvc 编辑视图中有以下 RadioButtons：-

<div class="editor-label">
    @Html.LabelFor(model => model.InsuranceSettled)
</div>

<div class="editor-field">
    @Html.RadioButton("InsuranceSettled", 1) Yes
    @Html.ValidationMessageFor(model => model.InsuranceSettled)
</div>

<div class="editor-field">
    @Html.RadioButton("InsuranceSettled", 0) No
    @Html.ValidationMessageFor(model => model.InsuranceSettled)
</div>

但是我如何根据模型值选择所需的单选按钮，所以如果 model.InsuranceSettled 值为 0，则选择 No 单选按钮，反之亦然.. BR

Answer 1

我建议RadioButtonFor改用。我认为最好使用强类型帮助器来生成您的输入，以确保您的输入具有正确的名称。他们还将根据您的模型自动选择默认值。

@Html.RadioButtonFor(model => model.InsuranceSettled, 1) 

@Html.RadioButtonFor(model => model.InsuranceSettled, 0) 

Answer 2

试试这个：

@Html.RadioButton("InsuranceSettled", 1, Model.InsuranceSettled == 1)
....
@Html.RadioButton("InsuranceSettled", 0, Model.InsuranceSettled == 0)

Answer 3

@Html.RadioButtonFor(model => model.InsuranceSettled , "True", model.InsuranceSettled == 1? new { Checked = "checked" } : null)

@Html.RadioButtonFor(model => model.InsuranceSettled , "False", model.InsuranceSettled == 0? new { Checked = "checked" } : null)
