PowerBuilder Journal. The DropDownDataWindow (DDDW) edit style is one of PowerBuilder's outstanding features.
Yes, I know there are a lot of new and exciting capabilities in the upcoming release of PowerBuilder, but in this article I'll try to solve some of the current problems with the existing features that are popping up in nearly every project I've seen. Here I'll focus on DropDownDataWindows, including: How to get started with DDDWs Filtering DDDWs without losing the display value in other rows Catching the collapsing of a DDDW Trapping the cursor keys in a DDDW Autocomplete DDDW values Getting Started The basics are well covered in the PowerBuilder User's Manual, but if you still have problems defining them look at Figure 1.
Click on the column you want and its edit style (yes, click on edit on the properties) as DDDW (choose DropDownDW as Style Type). Next, choose your DataWindow, display column, and data column.

PowerBuilder does have intellisense Well, intellisense is something specific to Visual Studio I believe, but PowerBuilder does have something called Autoscript that isn’t nearly as cool as intellisense but it is very useful. PowerBuilder Intellisense I wouldn’t have wasted the time writing a blog post about this until I learned that all the developers at the shop I’m working were not aware of PowerBuilders’ version of Intellisense. I don’t know exactly when Autoscript became available for PowerBuilder but it seems like it has been a long time, maybe version 9 or 10.
Activating Intellisense (Autoscript) in PowerBuilder Turning on Intellisense for PowerBuilder is pretty simple, which is why I was so surprised nobody here knew about it. You need to open an object (or at least I think so), for example just open one of your objects for editing which will give you the “Design” menu item.
