I have datawindow with 10 similar double field for edit. During runtime, I will try to insert 10 rows to the DW control and make it become a 10x10 field for input value. Now since I need to compute the subtotal for rows and columns and so I intialise each field with zero. However, for easy viewing, I would like to suppress showing all the zero value. I've try to set a rule in the datawindow object in the column.color attribute, like "if ([column] = 0, rgb(255,255,255), 0)" However it doesn't work well since when I try to input value, since the font color is now white(same as backgroud), I can't view the value before I jump to another field. Do anyone have other good and easy suggestion?
