Hello Guys,

I'm doing a project for use a datawindow of dynamic way at time of show it in screen, and i'm trying to do that the datawindow be able of the ubicate oneself in x and y points of the column that's focused when who's shown.

i did that so, but that never ubicate exactly were i want

someone has the knowledge that how do i can to do this?

I think I understand what you want to do.

I've attached a small sample application (pb 12.6). 

The coded events are on the main window, dw_main:

- constructor

- getfocus

- itemfocuschanged



- constructor


The constructor events are just a way of showing how to check if your datawindows are in powerbuilder units and not something else like "pixels"). If they are in pixels and you cannot change that, you have to convert the y-position of the column in dw_main to Units first in your code. (PixelsToUnits())


Suerte un saludo!

I've noticed that when you type in more than 10 characters, the itemerror event fires and the dw_follow is back to it's original position.

To avoid that, add this code to the dw_main.itemerror event:

this.event POST itemfocuschanged(1, dwo) // dwo is an argument of the event.

Greetings, Daniel -

It appears you may be attempting to emulate a column that uses the drop-down DataWindow (DDDW) edit style. Is there a reason why you are not using this native functionality within PowerBuilder? If you're not familiar with how to use a DDDW, the Appeon Community will be happy to help you learn how.

Regards, John
