我有一个包含 GridView 的用户控件。当我在 aspx 页面中使用此用户控件时，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。
您有任何解决方案可以更快地获得它吗？
1.用户控制
1.1.Html 父网格：
<asp:GridView ID="gvChannelUC" name="gvChannelUCName" />
子网格：
<asp:GridView ID="gvContentServerUC"

2.1.Html:Place Holder 用于添加动态 UserControl
<asp:PlaceHolder ID="phDevices" runat="server" >
</asp:PlaceHolder>
代码隐藏：
页面加载（）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
