What is the best method multi-select in dropdown DWs be accommodated for users.  This is an important issue for our reporting.  It does not appear to be a native PB functionality for DDDWs.

Hi Chris.

Could you elaborate on the "drop" event (pbm_dwndropdown ? ), and how you cancel the dddw ? 

TIA

Mickey

I couldn't get the pbm_dwndropdown to trigger at all, but pbm_command with notificationcode = 256 seems to do the trick.

I have no problem with pbm_dwndropdown. Check that you con't have two different events with this event id.

Hi John;

  FWIW: What I do on the "Drop" event of the DDDW is to intercept that user defined event, cancel the DDDW & instead, open a response dialogue. In that dialogue, I use a Tabular "List" DW where the App user can select more than one row. When the Response dialogue closes, I pass the multi-selection values back to the calling DWO / Window for processing.  Food for thought.  HTH

Regards ... Chris

You have to simulate the functionality, as the DW is not designed to do this. I found this example by doing a web search:
