Problem with updating a user control

Question

Hello to everybody. I have this problem:

I have a main form in which I'm loading a user control, which contains a datagrid (the datagrid shows some data). The insertion of the data I do it from another form (fInsertData). That I want to do is to change some fields from the fInsertData, to press "save" and then immediately refresh the data which the datagrid shows on the user control. In the same way the Microsoft Outllok Express works with the contacts.

Any idea?
