Hi,
    I am new to vb.net, and I have a question regarding how to color-code the cells in a dataset.  I have 2 tables in a dataset: revenue and expense.  Now what I need is to color the cells based on their values.
   This is an example of how the revenue table looks like:

                                   1999                       2000                2001
Shoes                           97.5                        55.6                  78.5
Jewelry                        105.1                      ------                 97.5
Clothes                         -----                       15.5                  14.8
bags                             45.8                        -----                  25.6

   The dashes means that there are no data available.  Now my problem is to color the fields according to their values.  For example, for year 2001, I need to color the field with highest value to be red = RGB(255, 0, 0) and the lowest value to be black = RGB(0, 0, 0).  Then the rest distribute the color evenly.
I tried to use the paint method from here, but that only work if you color the cell based on value range, HOW CAN I LOOP THROUGH THE COLUMN AND COLOR BASED ON THEIR VALUE?
    Thanks in advance!
