Just to make sure I’m on the right page: You have a drop down list with items. Picking an item from the list shows data related to that item in a GridView. Picking the second item on the list, “Add New Item”, shows a different window which allows you to add a new item. You don’t want the process of adding a new item to interupt any activities going on on the GridView page. After adding a new item you want the items listed in the DropDownList to automatically update.

I would suggest using AJAX with a Modal dialog box for adding the item and a web service/page method to handle the actual adding process behind the scenes. Then use javascript to add the new item to the dropdownlist.
