Also I tested the old .Net ComboBox for curiosity. As I expected, it worked like a charm. In the docs it says: "ComboBoxAdv is an advanced combo box control that provides a similar object model as the framework of the ComboBox control". So....what's wrong?

Thanks for contacting Syncfusion Support.
We are unable to reproduce the reported behavior with ComboBoxAdv in normal cases. We have prepared a sample and video for your reference and it can be downloaded from here.
Could you check with the above sample and let us know whether we have followed the same steps to reproduce the reported behavior? If not, please provide some additional details like Code Customization or sample that can reproduce the reported behavior? It will be helpful for us to analyze and provide you a prompt solution as early as possible.
