Question

如何从代码隐藏中填充引导下拉列表？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);
    }

这会添加项目，但它会完全失去<li> - 项目上的引导程序设计。另外，我如何知道哪个值为DataTextField，哪个为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

您可能更容易使用文字添加它们，如下所示：

Dropdown.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>

Dropdown.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;
}
