UserControl减慢了Aspx页面的速度

Question

我有一个包含GridView的usercontrol。当我在aspx页面中使用此usercontrol时，它工作正常。但是当我在GridView中选择一行时，它的工作速度很慢。

你有什么解决方案可以让它更快吗？

1.UserControl

1.1.Html 父网格：

 <asp:GridView ID="gvChannelUC" name="gvChannelUCName" />

ChildGrid：

<asp:GridView ID="gvContentServerUC" 

1.2.CodeBehind：

PageLoad（）函数

    {
//Fill data for ParentGrid
    DataTable dt = new DataTable();
                DataRow dr = null;
                dt.Columns.Add(new DataColumn("fullIndex", typeof(string)));
                dt.Columns.Add(new DataColumn("IPAddress", typeof(string)));
                dt.Columns.Add(new DataColumn("SubNetMask", typeof(string)));
                dt.Columns.Add(new DataColumn("Port", typeof(string)));
                dt.Columns.Add(new DataColumn("MaxConnect", typeof(string)));
                if (valuesUC.interfaces!=null)
                foreach (IPSInterface IPSInteface in valuesUC.interfaces)
                {
                    foreach (IPSChannel ipsChannel in IPSInteface.channels)
                    {
                        dr = dt.NewRow();
                        dr["fullIndex"] = ipsChannel.fullIndex;

2.Aspx主页

2.1.Html：Place Holder用于添加动态UserControl

<asp:PlaceHolder ID="phDevices" runat="server" >
                                            </asp:PlaceHolder>

代码隐藏：

PageLoad（）函数：

//Add more dynamic UserControl to PlaceHolder
    foreach (DataRow row in dtDevicesListByRole.Rows)
                {
                wuc[i] = (Test2.SetupGroup.Ipservice.IpInterfaceUC)LoadControl("IpInterfaceUC.ascx");
    }

如果您需要详细信息，我会添加更多。谢谢
