c# - 使用 C# 填充 bootstrap 下拉列表

Question

如何从代码隐藏填充 Bootstrap 下拉列表？现在我正在尝试这个:

    HtmlGenericControl li;

    for (int x = 3; x <= 10; x++)
    {
        li = new HtmlGenericControl("li");
        li.Attributes.Add("class", "myItemClass");
        li.InnerText = "Item " + x;

        myList.Controls.Add(li);
    }

这确实添加了项目，但它完全失去了 <li> 上的 Bootstrap 设计-项目。另外，我怎么知道哪个值是 DataTextField这是 DataValueField ？

下拉 html:

<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
    Dropdown
    <span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1" id="myList" runat="server">

  </ul>
</div>

Answer 1

使用文字添加它们可能会更容易，如下所示:

下拉.aspx:

<div class="dropdown">
    <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-expanded="true">
        Dropdown
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu" aria-labelledby="dropdownMenu1" id="myList" runat="server">
        <asp:Literal runat="server" id="litDropDown"></asp:Literal>
    </ul>
</div>

下拉.aspx.cs:

for (int x=3; x<10;x++)
{
    string liText = "";

    liText = liText + "<li role=\"presentation\">";
    liText = liText + "<a role=\"menuitem\" tabindex=\"-1\" href=\"#\">";
    liText = liText + "Item " + x;
    liText = liText + "</a></li>";

    litDropDown.Text = litDropDown.Text + liText;
}
