I'm working on a custom module and at one point during the processing the user clicks a button near the bottom of the screen.  Once the processing on the button is complete I would like to automatically scroll the window back to the top of the screen where information has been updated because of the clicking of the button.  Can someone point me in the right direction as to how I can  scroll back to the top of the window programmatically?   Any help is much appreciated.

That would do it but it requires the user to click on the button. 

Maybe it would help if I gave some more specifics.  On the page there is a datagrid list and the user of the site checks those items in the list that they are interested in and then clicks on a button below the datagrid to add the items to their customized list.  The customized list is shown at the top of the screen.  So... this is what happens. They click on the button below the datagrid to add the items to their list and I add them to the list. That's all working fine but the page stays at the bottom of the datagrid and I'd like to automatically take them back to the top of the screen so they could see the changes in their list.  I don't want them to have to click on anything beside the button that adds the items to their list.

Any ideas?
