First You can try using datasets for avoiding logon credentials to be provided everytime crystal report is to be viewed. If you are using dataset make sure your dataset is preserved between each postback by storing the "session" dataset.

Second pass logon credentials programatically for the database being used. Passing logon credentials is explained in lot of forums.

Third, if you are using Submit button for viewing the report, make sure you effect a full postback on submit button click. You will find that all pages in the report will work perfectly fine.

Note: Use Trigger with Update Panel to Effect the Full Post Back (The Control ID of the trigger should be the ID of the button).
