You can use the second 'iif' statement:
"IIF(items.secondary, RGB(193,255,255),iif(condition,RGB(..), RGB(255,255,255)))"

If you need still more 'iif', you can add method that set color based on complicated conditions.

I have a grid with 14 columns. The backcolor of 4 of the columns is grey. Now I need to set the backcolor of the other 10 columns dynamically based on data. In the init of the grid I have:

This.SetAll("DynamicBackColor", "IIF(items.secondary, RGB(193,255,255),RGB(255,255,255))", "Column")

But of course this sets the columns that should be grey to white. I cannot figure out how to write the code to account for those 4 columns and keep they grey.

Any suggestions?

TIA!
