Html.RadioButtonFor MVC綁定

Question

我的視圖有一個字符串屬性。 通過操作結果執行get請求並發送到視圖 - 它看起來像這樣：

public ActionResult TeaCoffeView(string teaOrCoffee)
{
    MyModel model = new MyModel();
    //do some stuff
    //teaOrCoffee has two values , if "T" i have
    //to make the view as tea radio button selected 
    //or if it has "C" then coffee radio button selected 

    return View(model);
}

我的觀點.cshtml

@Html.Label("tea:")
@Html.RadioButtonFor(m => m._teaOrCoffee, Model._teaOrCoffee)  
@Html.Label("coffe:")
@Html.RadioButtonFor(m => m._teaOrCoffee, Model._teaOrCoffee) 

模型

public string _teaOrCoffee {get; set;}

如何將值與@Html.RadioButtonFor綁定，以便在加載時它應顯示為選中狀態？

Answer 1

使用@Html.RadioButtonFor()的第二個參數來設置應該選擇它的值。

@Html.RadioButtonFor(model => model._teaOrCoffee, "T") @Html.Label("tea:")
@Html.RadioButtonFor(model => model._teaOrCoffee, "C") @Html.Label("coffe:")
