Is it possible to display or hide zero values in a UltraGrid like in Excel?  I've bound an ultragrid to a list of objects.  Some of the properties of the object are of integer and decimal types.  When I do a add new row (i.e., when a new object is created), I want to show blanks instead of 0 or 0.0 in these fields.  Excel has a feature to do this (http://office.microsoft.com/en-us/excel/HP051998791033.aspx).  Is there a way to do the same using UltraGrid (Wingrid)?
