Error: Control with ID ObjectDataSource1 being registered through RegisterAsyncPostBackCon

So I solved my problem by not using ObjectDataSource Events as Triggers for UpdatePanels. This used to work ATLAS CTP, but now I replaced it with the respective GridView / FormView events and everything is back to working. Anyone know why ObjectDataSource Events can't trigger Update Panels anymore?

I am having this same issue. How would I do the following using the GridView events?

Thanks!

<asp:UpdatePanelID="p1"runat="server">

<ContentTemplate>

<asp:GridViewID="GridView1"runat="server"DataSourceID="photosDS"AutoGenerateEditButton="True"AutoGenerateDeleteButton="False"DataKeyNames="PhotoID"AutoGenerateColumns="False">

<Columns>

<asp:TemplateFieldShowHeader="False">

<asp:LinkButtonID="lnkBtnDelete"runat="server"CausesValidation="False"CommandName="Delete"

OnClientClick="return confirm ( 'Are you sure you want to permanently delete this image? You will not be able to restore it.' )"Text="Delete"></asp:LinkButton>
