selection-list programmatically select all

[freak]

Using Progress 9.1d, is there a way to programmatically select all list items in a selection list?

Hi, add button with this:

    ASSIGN SELECT-1:SCREEN-VALUE IN FRAME {&FRAME-NAME} = SELECT-1:LIST-ITEMS NO-ERROR.  


    APPLY "VALUE-CHANGED":U TO SELECT-1.

and mark multiple-selection in Property-Sheet of SELECT-1.

Regards.

Works very well! Thank you. But what is the last line required for?

Usually you may want to respond in some sort when the user selects a different value - and thus causing the VALUE-CHANGED event to occur. The APPLY statement is invoking that event in your code - just like if it would have caused by the user. That way your response trigger will fire.

Ok... I didn't see the need to trigger a value-changed event for selecting a value that is why I questioned it. Thank you!

If you programatically change the value of a widget and want the program to respond to that change then you always have to trigger the value-changed operation yourself, otherwise it will be ignored.
