Hi, thanks for the quick reply. My appologies, I should have said that it is the SmartDBView (SdbV) that is giving me problems and not the SmartDataSource. When I place the SdbV on my page it works fine when I run the page. When I configure the SdbV and then run the page it then throws the exception described.

• I'm not sure if I can send you my full project as it is in access of 50mb
• I am developing a website and is currently running it as a file system on my laptop. I test it with "View in browser" from VS2010 with ASP.Net dev server.
• Below is the stack trace report

• What is the location of the smartDBtemplates folder in your ASP.NET project? Is it located at the root?
• What is the location of the problematic .aspx page? Is it in nested subfolders?
