这应该找到div你需要的:

var div = (HtmlGenericControl)pnl.Controls[0].FindControl("divMessage");

我创建了一个新页面并通过它进行了测试:

<%@ Page Language="C#" Inherits="System.Web.UI.MobileControls.MobilePage" %>
<%@ Register TagPrefix="mobile"
    Namespace="System.Web.UI.MobileControls"
    Assembly="System.Web.Mobile" %>

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        var div = (HtmlGenericControl)pnl.Controls[0].FindControl("divMessage");
    }

</script>
<body>
    <mobile:form id="form1" runat="server">

    <mobile:panel id="pnl" runat="server">
        <mobile:DeviceSpecific ID="device" runat="server">
            <Choice>
                <ContentTemplate>
                    <div id="divMessage" runat="server">test.....</div>
                </ContentTemplate>
            </Choice>
        </mobile:DeviceSpecific>
    </mobile:panel>

    </mobile:form>
</body>
</html>
