* Grid.Init this.column3.DynamicBackColor = "IIF(mycondition = somevalue, RGB(255,0,0), RGB(255,255,255))"For the grid cell which does not have a focus it has to show the appropriate backcolor.

this.column3.DynamicBackColor = "IIF(mycondition = somevalue, RGB(255,0,0), RGB(255,255,255))"and this will not:
this.column3.DynamicBackColor = "IIF(mycondition = somevalue, RGB(255,0,0), RGB(255,255,255)) "The reason is in one extra space in the IIF expression between the last bracket and closing quote.
