Help: Problem with Crystal Reports XI

I have created a report using crystal reports XI, and all things are good. I can view the users which is listed in my database table.
But one thing I noticed is whenever I add a user to my database during run-time (on the Application), and then I go back to the reports in my Application, when I click the button where I link the Crystal_report_viewer, the users, or the table is not refreshed. Or not filled with the new user that was added/inserted to the table.

Kindly if someone knows how to refresh it, it would be a pleasure for me hearing from you guys.
Happy holidays guys.

PS: I created a .rpt first in Crystal Reports, and then on my .Net project I add the SQL query,connection to the dataset,etc. and then open the .rpt file from the .net using codes.
