我有一个数据列表，其中有一个打开 Modalpopupextender 的按钮。此 modalpopupextender 中有一个未触发的提交按钮。请指教。

</table>解决方案
您需要对代码进行以下更新：
将<asp:Panel ID="Panel3" runat="server"DataList 移到外部，使其不会被多次渲染。
要在服务器端获取单击项目的 coachId，请执行以下操作：
添加<asp:HiddenField外部数据列表
<asp:HiddenField ID="hidSelectedID" runat="server" />
在 MessageCoach 按钮上添加 OnClientClick 处理程序以在隐藏字段中设置 id：
<asp:Button ID="btnMessageCoach" runat="server"
OnClientClick="javascript:document.getElementById('<%=hidSelectedID.ClientId%>').value='<%#Eval("CoachId")>';" Text="Message Coach" Style="border-radius: 5px; height: 30px; background: #32BC29; width: 180px; font-size: Medium; color: Black;"></asp:Button>
在 btnSendMessage_Click 句柄内，您可以使用访问隐藏字段值hidSelectedID.Value
