I need to use ajax controls on a Table in an existing website. The web page has been developed using Visual Studio Express 2013 and I have tested the changes in a separate website and it works fine. However, when I import the page into the existing website
I get compilation errors "Unknown server tag 'asp:ScriptManager'" and "Unknown server tag 'asp:UpdatePanel'".
I have placed the ScriptManager control immediately before the table followed by the UpdatePanel and ContentTemplate with the end tags for the UpdatePanel and ContentTemplate following the Table end tag.
I thought maybe I had omitted some entries in the web.config file but the web.config in the test website contains very few entries.
Does anyone please have any suggestions?
