I'm facing a problem with the MulticolumnCombobox that results in an SelectedValueChanged-Event when the list is dropped down the first time after data source was set. Please use the attached project for reproducing the problem using the following steps:
- Start Application on Windows 10 Chinese (Note: The described behaviour will not occur for other cultures (i.e. German will not fire the event at that time))
- Click the Button having the Text "RadButton1", which will set the DataSource and fire the event "SelectedValueChanged" (MessageBox will pop up) which is okay at this point.
- Now perform the drop down for the Combobox. Using Windows 10 Chinese will fire "SelectedValueChanged" and Windows 10 German will not fire "SelectedValueChanged".
==> As the MulticolumnCombobox performs different based on the culture, this seems to be a bug.
If you need further information, please do not hestitate to ask.
