动态添加 ASP DropDownList 到 li 控件

Question

我有以下代码：

        HtmlGenericControl li = new HtmlGenericControl("li");
        ULRouting.Controls.Add(li);

        HtmlGenericControl anchor = new HtmlGenericControl("a");
        li.Attributes.Add("myCustomIDAtribute", "11");
        anchor.InnerText = "TabX";

        li.Controls.Add(anchor);

我正在尝试了解当您动态创建 li 时如何将下拉框添加到 li 控件，即：

 <asp:DropDownList ID="cmbRoutingStage_1" runat="server" DataSourceID="sqlDBStages" DataTextField="stages" DataValueField="StageRefID"></asp:DropDownList>

Answer 1

试试这个：-

DropDownList ddl = new DropDownList();
ddl.ID = "cmbRoutingStage_1";
ddl.DataSourceID = "sqlDBStages";
ddl.DataTextField = "stages";
ddl.DataValueField = "StageRefID";
li.Controls.Add(ddl);

作为旁注，您可以使用HtmlAnchor 类来生成锚标记：-

HtmlAnchor anchor = new HtmlAnchor();
