Sorry for reposting - can not figure out...
in [VB.NET]

From: J Snaith on 5 Apr 2010 08:28 Hi Mike. Well I've tried many different things in the timer interval to accomplish this task, however, something is not working. Both panels display at same time and don't disappear. I don't think I'm familiar enough with timer to complete this. Do you have any further advice on how this task can be accomplished? Appreciate any feedback and guidance, thank you kindly.

Something like this: <asp:UpdatePanel ID="UpdPnl" runat="server"> <asp:Panel ID="pnlViewPhotos" runat="server"/> <asp:Panel ID="pnlWarning" runat="server" visible="false"/> </asp:UpdatePanel> -- Mike

Thanks Mike. Appreciate the comments and link. Read the contents nut am still now sure how to apply this to my case. I've been trying and trying but cannot get my stuff to work as I want. There must be a way that I am missing.
