What's the difference between <%=... and <%#...

You may have discussed this earlier in the book but I couldn't find it.

I'm sure Imar will have a much better explanation but basically <%= is the same as using Response.Write you are basically writting a string out to that spot.

<%# is accessing a data object

hopefully that helps a little bit.

Thanks, yes it does.

I've been playing around with it and it appears that the following "Might" be true "Please correct me if I'm wrong"

<%# is used with server controls and <%= are used with HTML controls. For instance I cannot access the code Behind when I use <%= but I can when I use <%# (I could also be doing something wrong)

Nope, it's not about server controls versus HTML controls. As alliancejhall pointed out, it's about databinding (<%#) versus Response.Write (<%=)

Data binding expressions are evaluated long before output is sent to the browser in data binding scenarios while Response.Write direct outputs content to the response stream.

You may want to read the following articles (and follow some of the links to more detailed pages) to find out more about the differences:
