Chris,

Using viewstate sends all of the viewstate objects' data to the browser on each postback. Using sessionstate keeps the data on the server.

This can have a large impact on speed.

>I wonder if it would be better to use ViewState in this situation. I am not sure, but I thought it was better to use Session when moving to a different page, and ViewState for postbacks. I am not really sure there is any difference.
