Hi!
Today I wanted to change the left image on one of the nodes of an UltraTree and suddenly all nodes disappeared. I did an undo, tried it again with same result. Instead of changing the image I tried to add a new node but again, all nodes disappeared. I had this UltraTree for nearly 3 years now, last change has been a long time ago but there have never been problems. When I looked into the .Designer.cs part of the class I could see that VS Designer removed all nodes, the instance of UltraTree was still there.
I tried it with other UltraTrees in my project and all had the same behaviour. For testing I added an empty Form to my project and an UltraTree onto that Form and that worked, I could add nodes, images without a problem. I compared the working and not working forms and after a while I figured out that if one or several nodes also has a Key specified this causes the problem. When I removed the key from my main working class there where no problems, the other way around if I added a Key to one node in the test form the nodes disappeared! Unfortunately I need the keys so I cannot simply remove them.
I'm using NetAdvantage 10.2 in VS 2008 on Windows XP Professional but the behavior is the same on Windows 7, tried it on a colleague's machine. Looks like a bug to me.

This sounds a bit like bug 35316, the fix for which I believe made it into the latest service release. You should try this with the latest service release, and if you still have a problem report it as a bug.
Hi Brian,
thanks for the instant reply. I've installed the Service Release which fixes my problem. Btw, is there a way to get informed when Service Releases are available? The subscriptions are managed by our IT-department which is informed about major product releases but not the Service Releases. Do they have to do something more or are Service Releases simply not announced?
