剃刀视图@ Html.RadioButtonFor

Question

I have the following bit of Razor code:

@{
    foreach(var item in ModelBasket.AvailableOptions)
    {
      if (item.Enabled)
      {

      }
    }
}

each item has a Selected property and description property. I want to create a radio butoon for each item but if I try and do the following in my if statement:

@Html.RadioButtonFor(item.Description, item.Selected, new {@class = "radio__input" })

it just red lines under item.Description with cannot resolve item.

Just to test in my if statement if I put <p>item.Description</> then this is literally what gets rendered and not the item description as I'd expect.

Answer 1

我相信method参数需要一个lambda，例如：

@Html.RadioButtonFor(item => item.Description, new {@class = "radio__input" })

Answer 2

Try this, add the option checked. @Html.RadioButtonFor(item => item.Description, new {@class = "radio__input", @checked = item.selected })
