Update div in site.master.

Question

Hi my current system has a screen where the user can input a value into a table using a stored proc. The newly input item is then shown inside a datagrid that is nested within a DIV within the site.master page so it shows on ever webpage. However when on the input screen after the user has clicked the insert button and the item has been saved it looks as if the page is being refreshed but the datagrid within the site.master is not updated.

Is there any way that i can get this to update after the insert has happened without navigating to a different page?

Thanks Boldonglen.
