How do you refresh a datagrid from a different form?

Hi Everyone,

I have an app that opens up 3 forms. 2 forms have a datagrid the other form has book lending details. The datagrid forms are for books in the library and books that have been borrowed.

Both datagrid forms will be open as shown in the attachment, how do I refresh the "Borrowed Books" datagrid form from inside the form that has the "Book in Library" datagrid.

So far I've been able to update the "Books in Library" datagrid because control comes back to that form after the details form closes but since the "Borrowed Books" form is still opened up, we would like to refresh the datagrid on that form.



Thanks.

Truly,
Emad
