Question

我正在从代码隐藏中动态创建UI。 UI放置在内容占位符中，其中包含带有其名称的复选框图像。名称来自SQL。

    Try
        Dim QryCount As String = "query to retrieve the data"
        Dim TblCount As DataTable = connection.GetDataTable(QryCount, sqlcon)
        Dim count As Integer
        count = TblCount.Rows.Count
        If count <> 0 Then
            For Each RowCount As DataRow In TblCount.Rows
                str= RowCount("str_name").ToString()
                Hit_count = RowCount("Download_Count").ToString()
                TT = RowCount("ToolTip").ToString()
                u_id = RowCount("id").ToString()

                URLData1 = URLData1 & "<input type='checkbox' runat='server' id='check" & u_id & "'/><label for='check" & u_id & "'> <img src='images.png'/><br><a href='simple.aspx?ID=" & u_id & "'title='" & TT & "' target='_blank'>" & str & "</a><span style='font-size: 8pt; font-family:segoe ui;color: #3399FF;'>&nbsp;&nbsp;[" & Hit_count & "]</span>

下一个 lblCol4.Text = URLData1

并且ui页面包含的代码为

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

 <div>
        <asp:Button runat="server"  ID="btnsubmit" Text="Submit" />
    </div>


<div class="columns">
    <asp:Label ID="lblCol4" runat="server" Font-Names="Segoe UI" Font-Size="Small" style="text-align: center"></asp:Label>
</div>

这是一个多选复选框。用户选择并单击提交按钮后，我将尝试读取所选的复选框ID属性，以便可以从SQL检索相应的数据。我是asp.net的新手，请帮助我
