I have a treeview control which I am populating with two first levels that have two levels below them for a total of three levels. Everything has been working great until I added a third first level.

The new first level is expanded initially so the second level is visible. When I click the plus sign at the second level, it expands and the plus sign disappears. The other first levels don't do this so it must be a coding error on my part.

Does anyone have an idea of what is causing this?

Can you post a screen print of there's no sensitive data?  It doesn't change to a minus sign?  Tbh it sounds like a bug.

Have you tried to use the TV DW instead and see if it does the same? I've had good luck using the TV DW and building the ds behind it manually when needed.

I haven't looked into TV DW. I might as the TV control has an irritating flaw: there is no gap between the checkbox and the image.

The plus sign goes away and no minus sign appears in it's place.

Not really sure, but I've seen a bug in v. 2017 on the last level of not expanding on the last first level. (which now seems to have been fixed).

I think the TV control is quite buggy and you should try to make a sample app and report this as a possible bug.

regards.

It is my PBSearch which is PB 10.5 but I migrated to PB 2019-R2 to test this issue. The issue still happens in PB 2019-R2 so I suspect somehow I'm coding it wrong.

See the attached image.

Does it also happen in PB 10.5 or you mean only happens in PB 2017 and 2019?

It happens in 10.5 and 2019. The other nodes work fine so I am thinking I missed something adding the new node.

Or something is wrong with your Windows OS installation. I recommend trying this out on a different computer to rule out it is environment issue.

Hi Roland;

   In your TreeViewItem structure do you set Children = TRUE in that IM branch at the 2nd level?

Regards ... Chris

I figured out my problem.

I was adding the third level during initialization instead of from the itempopulate event like the others. I'm not sure why but at least it is working now.

Thanks for the suggestions.

 

Does anyone know of a way to insert a few pixels of space between the checkbox and icon? There are touching each other which is not a good look. I am using Send to adjust the vertical spacing but there doesn't appear to be a message to adjust the checkbox/icon spacing.

This might not be a viable workaround, but how about replacing the icon with a smaller one? A different one?
