UserControl slowing down Aspx page

[lambary]

I have a usercontrol which contains a GridView. When I use this usercontrol in aspx page it works fine. But when I select a row in the GridView, It works very slow.Do you have any solution for getting it faster?1.UserControl1.1.HtmlParent Grid:\[code\] <asp:GridView ID="gvChannelUC" name="gvChannelUCName" />\[/code\]ChildGrid:\[code\]<asp:GridView ID="gvContentServerUC" \[/code\]1.2.CodeBehind:PageLoad() function \[code\] {//Fill data for ParentGrid DataTable dt = new DataTable();
