I have a grid in a user control.  Data is loaded on the PreRender event.  There is a checkbox "Delete" column for allowing the user to delete selected rows when the Save button is pressed.  I am trying to construct an ArrayList of changed rows in UpdateRowBatch, but UpdateRowBatch is never called and the grid contains no rows in the Page OnLoad event.  I have another page where I use the grid (right on the page, not in a control) directly using the same events and that works perfectly.  Is there something I need to do for using the grid in a user control to make sure the data is available in the OnLoad event or to get the UpdateRowBatch event to fire?

thanks
