Hi, I just had a quick question.  I have a Gridview with a linkbutton template column that fires the Gridview_RowCommand Event and this opens a modalpopup.  I would like to use the AJAX updatepanel to prevent the the entire screen from posting back when the linkbutton on the grid opens the popup but not sure how to go about it given the fact that I cannot point the linkbutton to an invisible button (so it can be attached to the async trigger) because I need to know which row on the grid the user clicked.
