Hi, i have a panel with one combobox based on a listdatasource and displayNullOption=Y. So, it must be possible to select nothing. After starting the panel i can see no value and have to click on the combobox arrow to select a value. Now i want to see which value the user has selected. I have found 2 ways:
or
Both ways work seem to work... HOWEVER: when the user selects the null option in the list, l_value_nr always gets the value of the first row in the datasource. So, it is never null. How can i detect that the user has chosen the null-value in the combobox? Kind regards, Jan Willem Vermeer |
Sorry, solved by myself. Made a small typing mistake. With KR Jan Willem |
