Question : force asp.net web page to post back from another web page

I have a web application with 2 pages the first page has a data grid and the second detail page is use to add records to the dataset that populates the data grid.  From the data grid page, the detail page is called to add a new record.  What I am trying to do is after the detail record has been updated and the window closed I want the datagrid page to automatically post back to refresh the data in the grid to reflect the addition of the new record.  I had tried populating a textbox set with autopostback = true via a javascript (this script also closed the detail page) but the autopostback feature only executes with user input and tabing off the control.  Basically I am looking for a code snippet, or method that will do this.  I have seen similar applications in action but have found little reference as to how they perform.   I figure it will have to be a client side javascript which is not my strong point. Thanks, Tom Majarov
