Hello,
I have column "period", i set an editmask like ### to prevent enter a non-digits characters.
When I clear this column (i expected null value in table) - there is always zero.
What I want to achieve: column with numbers only and null - when null then updates and sets null, when >= 0 then specific number.
I even try to use setnull on variable and then sets in datawindow (datawindow.setitem) but still - 0? Am I missing something?
