Hi All

Plz some body help

I'm using combobox in my WinCC 7.3 project with 9 rows but when i click the combobox in runtime the related drop down texts are shown far away from box. It is shown in attachment.

Hi,

I would recommend to install the newest update:

B.R

I am also facing this problem. I think updating installer is not solution. My wincc version is 7.5 .

I am also facing the same problem.

This happens when the combobox is placed on the upper side or the outside side of the screen.

Anyone that would happen to find a solution to this problem?

I run WinCC 7.5 and all the updates.

Its WinCC Runtime V7.5 + SP2 + Upd9.

The project is setup for two screens. One picture window with the same base picture for each screen. The problem occurs either way on computer with

One full HD screen: If the drop down is placed in the upper part of the screen it shows the drop down menu some 100 pixels under.

Two full HD screens: Same as one screen. Plus if the drop down is placed on the right screen, the drop down menu appears on the left screen.

One 4k screen. Same as case one and two.

This happens irrelevant of the picture window in which it is placed. It's a persistent problem. It did the same in the version 7.2 as well.

Apparently it is a ComboBox library problem when ComboBox is used in a picture window and the project is not generated using Project Designer. It is also a problem when the same picture window is opened on two different screens.

Apparently the content of the ComboBox receives different coordinates than than the ComboBox self.

I created a support request and after the first response which did not tackle the problem I was informed that the issue would be further researched by  Siemens and that it seems to be a library problem. I did not get another response yet. When I hear more I will post an update.
