Forms Data Controls :: Using Htmlencode On Detailsview And Gridview?

We are using gridview to display data and detailsview to show details, update, insert, and delete as needed. I am a bit confused on whether or not htmlencode and htmldecode is needed when storing data from detailsview. Gridviews always use boundfields and I think encoding and decoding is built in. For detailsview we use mostly templatefields (eval(), bind()), some boundfields, and some data is stored in codebehind using e.values[] or e.newvalues[].Here is where I've got the idea:http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.detailsview.itemupdated.aspxIf I use the iteration and htmlencode, detailsview read only mode displays decoded data. However, gridview displays encoded data and of course update mode of detailsview. So, it seems like detailsview using htmlencode and htmldecode somewhat, but I am not clear as to what degree and what would be the best way to handle it.
