Sry right i forgot to post this line, but i already had it. Its not
working, but i think maybe i am misunderstanding sth. i think i am only
doing this for images but i want the background color of the cell to have
different alpha values. maybe this isnt even possible?!
What i want to do ist to have one color e.g. Color.Green and depending of a
calculated value between 0-100% for each cell i want the cell to be lighter
green or darker green. i thought i could to this by making the
backgroundcolor transparent. Am i misunderstanding sth and if so does
anybody have a hint how i could solve my problem?
thx
