根据asp.net中另一个CheckBoxList列表的选定项创建新的动态checkboxlist

<asp:CheckBoxList ID="sourceCheckBoxList" runat="server" AutoPostBack="true" OnSelectedIndexChanged="sourceCheckBoxList_SelectedIndexChanged"></asp:CheckBoxList>
<asp:CheckBoxList ID="dynamicCheckBoxList" runat="server"></asp:CheckBoxList>

protected void sourceCheckBoxList_SelectedIndexChanged(object sender, EventArgs e)
{
    dynamicCheckBoxList.Items.Clear(); // 清空动态CheckBoxList

    foreach (ListItem item in sourceCheckBoxList.Items)
    {
        if (item.Selected)
        {
            // 根据选定项创建新的动态CheckBoxList
            CheckBoxList newCheckBoxList = new CheckBoxList();
            newCheckBoxList.ID = "dynamicCheckBoxList_" + item.Value;
            newCheckBoxList.Items.Add(new ListItem("选项1", "1"));
            newCheckBoxList.Items.Add(new ListItem("选项2", "2"));
            newCheckBoxList.Items.Add(new ListItem("选项3", "3"));

            dynamicCheckBoxList.Controls.Add(newCheckBoxList); // 添加到动态CheckBoxList中
        }
    }
}
