我有一个包含DataList的面板，它列出了带有复选框的公司。我想要做的是当用户单击特定公司的复选框时，它将发送CompanyID，因此我可以对数据库进行一些更新。我不确定如何将值存储在复选框中，并在用户点击时发送。
这是DataList
<asp:Panel ID="pnlChildView" runat="server" style="padding-left:200px;">
<asp:DataList ID="childList" runat="server" Width="100%">
<ItemTemplate>
<div class="div_hover">
<table class="table1" width="80%">
<tr>
<td style="width: 60%; border-right:0px solid black; border-spacing:0;">• <%#Eval("CompanyName")%></td>
<td style="width: 20%;text-align:right; "><a href="/Apps/ERP/Other/CompanyInfo.asp?CompanyID=<%#Eval("CompanyID")%>" ><%#Eval("CompanyID")%></a></td>
<td style="width: 20%;text-align:right;"><asp:CheckBox id="chkChildCompany" runat="server"
AutoPostBack="true"
OnCheckedChanged="chkChildCompany_CheckedChanged" /></td>
</tr>
</table>
</div>
</ItemTemplate>
</asp:DataList>
</asp:Panel>
以下是活动：
protected void chkChildCompany_CheckedChanged(object sender, EventArgs e)
{
Response.Write("Child Checkbox is checked, CompanyID: " + CompanyID (sending from the checkbox event);
}
任何想法如何隐藏CompanyID并在复选框点击事件时捕获它？
谢谢，

将此代码用于aspx文件

这个代码隐藏在后面，即aspx.cs文件

childList.DataSource = companyList;
childList.DataBind();
}
[System.Web.Services.WebMethod]
public static string saveComanyId(string idList)
{
string response = "false";
try
{
var ids = idList.Split(',');
foreach (var id in ids)
{
//Code for saving id in DATABASE
}
response ="true";
}
catch (Exception)
{
response="false";
}
return response;
//returing response true for success and false for failure
}
/*protected void chkChildCompany_CheckedChanged(object sender, EventArgs e)
