c# - 如何隐藏单选按钮列表中的单选按钮之一？

Question

假设我想隐藏一个值为 0 的单选按钮，什么代码可以使它可见 = false？我使用的是 Javascript、C# 和 ASP.NET。

<asp:ListItem Value="1"> 1&nbsp</asp:ListItem>
<asp:ListItem Value="2"> 2&nbsp</asp:ListItem>
<asp:ListItem Value="3"> 3&nbsp</asp:ListItem>
<asp:ListItem Value="4"> 4</asp:ListItem>
<asp:ListItem Value="0" Selected="True" Enabled="False">

foreach (ListViewDataItem item in ListView1.Items)
{
    var rbl = (RadioButtonList)item.FindControl("rblSelect");
    var selectedValue = int.Parse(rbl.SelectedItem.Value);
    var selectedText = rbl.SelectedItem.Text;
    var selectedIndex = rbl.SelectedIndex;
    rbl.Items[0].Attributes.CssStyle.Add("visibility", "hidden");
}

Answer 1

试试这个:来自 CodeBehind

MyRadioButtonList.Items[0].Attributes.CssStyle.Add("visibility", "hidden");

编辑:

int count = 0; //index of item tobe hidden
foreach (ListViewDataItem item in ListView1.Items)
{


    var rbl = (RadioButtonList)item.FindControl("rblSelect");
    var selectedValue = int.Parse(rbl.SelectedItem.Value);
    var selectedText = rbl.SelectedItem.Text;
    var selectedIndex = rbl.SelectedIndex;

    if(count == 0)
       rbl.Attributes.CssStyle.Add("visibility", "hidden");

    count++;
}
