leave dropdowndatawindow empty

[anneoctaaf]

I have a dw with a dddw. It is ok if the user leaves this column empty, but if he/she accidently clicks a value, the user can't get it empty anymore. Do i need to add a null value in the table with all the values? Or can i solve it just in PB...

Thanx, Salsa

open the dddw in the datawindow painter and ensure the following settings:
required - unchecked
allow editing - checked
empty string is null - checked
