Can you please try to add a setting in which the RadGrid update itself like this:
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"><AjaxSettings> <telerik:AjaxSetting AjaxControlID="btnAddContainer"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="gvContainerDetail" > </telerik:AjaxUpdatedControl> </telerik:AjaxUpdatedControl> </UpdatedControls> </telerik:AjaxSetting> <telerik:AjaxSetting AjaxControlID="gvContainerDetail"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="gvContainerDetail" > </telerik:AjaxUpdatedControl> </telerik:AjaxUpdatedControl> </UpdatedControls> </telerik:AjaxSetting> </AjaxSettings> </telerik:RadAjaxManager>and see how it goes.
