Is there a way to change the order that columns in a webdatagrid are displayed?  These columns are automatically generated from a databind.  The order of the columns is configurable by user, so it can't be hard-coded in any fashion.  Columns used with the old UltraWebGrid had a "move" method to accomplish this.  Is there a similar technique for a WebDataGrid's gridfield?  I've tried iterating across each column, setting the VisibleIndex property of each colum with the appropriate index, but this produced unexpected results (it seems as though the VisibleIndex for one column would change as I updated another).  Any help with this would be appreciated
