Could you please confirm whether the suggestion provided by Emanuel works for you? I was not able to reproduce the described issue using our latest release - Q2 2011 SP1. That is why I recommend that you update your version with the latest one. The latest release contains a lot of new features and we will appreciate your feedback. If the issue continues to appear, please send us your application so we can investigate it further.
Our investigations have shown that the usage of both WinForms
and WPF technologies in the same application can lead to performance and memory issues. In addition, we cannot guarantee that our controls will work as expected when hosted in a WPF application. I think the same is valid for WPF controls used in WinForms
host. Because of all this, we do not recommend mixing these technologies.
Should you have any other questions, please do not hesitate to write back.
