Question : Crystal in Visual Studio dynamic Database persistant on postback

I wanted to dynamically link my Crystal to the connection string in the Web config, I found code to do this. It works as long as I don't need to move off of page one. But moving off page one, (if dynamic logic is in (!IsPostBack) causes either the dynamic link to be lost and I get page 1 displayed empty.  Or moving off page one, (if dynamic logics is not in (!Ispostback) causes the logic to be reinitalized and I still find myself on page one, no matter what I do.. page next, page last, Enter a page # ..

so something, has to be to reset the connection.. But not all the logic,  so it doesn't keep resetting to page one..

Does anyone know the special secret of what to set and what not to set on a postback???
