table of .mdf database file didn't display inserted or modified record

Hi All.

I add Service-based Database ABC.MDF file and connect it to project. In database I created table and stored procedures. And base on it create table adapters in dataset and bidden form to it. The form can modify and add new record. But when add new record to the table or modify existing record ListView control display them. But when I open table I didn't see new record or modification of existing records. What is a problem? How to fix it?

Thanks.
