ASP.NET中的嵌套转发器控件

Question

我有一个带有多个视图的嵌套转发器控件。在此，父转发器绑定到数据表。当我们单击父转发器中的div时，子转发器将显示在下拉框中。但是我在父级中继器的所有视图中都得到了同一个子中继器实例。请帮助我解决问题。

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
    <ItemTemplate>
        <div class="row row-border pb-1 pt-1 border-bottom border-dark dropdown-toggle" data-toggle="dropdown">
            <div class="col-md-2">
                <asp:Label ID="LabelDate" runat="server" Text='<%# Eval("id") %>'></asp:Label>
