Edward, sorry but I need your help once more. I haven't get to change just one cell to read only. I tried the snippet in the when method and all the rows become read only. The dynamicCurrentControl I don't know how to use in conjunction with read only property.

I have one grid with 5 columns. Just the columns 2 and 3 are possible to enter or update data. But the user can update these columns ( I mean the rows of columns 3 and 4) only if the row of column 4 is empty.

TIA
