Editing data on a table from a different form in C#

I have a table for contact details ( made using in VS using C# 2010)

I want to have the table displayed in the form (called form1 for the purpose of the question), with various buttons (add new, edit, remove, search) on the right hand side.

Designing the form isn't the issue. I have so far created a form to add a new contact(form2), where I want the user to enter details for the contact (name, address etc.) and then save it, then form2 closes displaying form1, with the table updated displaying the contact they have just created.

How can I do this?
