>I have a procedure where I evaluate every field of the table and based on conditions cell or entire row should be painted in different color. when forms pops up grid should be colorful

Can you show your current code and what is not working?

Basically, you can do

thisform.grid1.column1.DynamicBackColor = "thisform.RefreshColors()"

and in the RefreshColors method of the form you would do

lnRGB = 0
do case

    case Field1 = 'Something'

       lnRGB = color number here
   case AnotherField = 'SomethingElse'
      lnRGB = different color number

  endcase

return lnRGB
