无法从 C# 中的 jQuery 对话框获取值？

Question

我在 ASP.Net 中使用 GridView 并添加 jQuery Dialog 以在 Edit 按钮上显示数据，当我单击 Dailog 的 Save 按钮时，它会加载 Dialog 并显示数据，我无法在 ASP.Net (C#) 中获取值代码隐藏。

<script type="text/javascript">
    $(function () {
        $("#Phone-Modal").dialog({
            autoOpen: false,
            height: 400,
            width: 430,
            modal: false,
            open: function (type, data) {
                $("#Phone-Modal").parent().appendTo($("form"));
            }
        });            
    });
    function showDialog(id) {
        $('#' + id).dialog("open");

    }
</script>

            </asp:GridView>

protected void ddlPhoneStatus_SelectedIndexChanged(object sender, EventArgs e)
{
string strTest = lblPhone.Text;
.....
}

当我单击对话框上的 DropDownList 的 SelectedIndexChanged 时，我无法将值从 jQuery 对话框获取到 C#。

检查你是否给了控件 runat="server" 属性
