I have renamed some pages and although it works fine at run time , in the navigation bar in design time I get the error "The Name 'Security' does not exist in the current context.
I'm not sure what I'm missing as I have done this previously an after moving to edit another page and then coming back to the page this error message goes.
Annoyingly the "issue" has gone on my application and the "error" message has gone. I guess this could be down to a recompile or just opening and closing the app.
I have seen this "issue" a couple of times, if I can replicate it perhaps using the northwind database I will send you a copy and how I got to the problem
Intermittent issues are always the tricky ones !
