Thank you for writing.
Note that when data binding RadMultiColumnComboBox
, the first item is selected by default. Hence, the SelectedIndex
property is set to 0. If you set the SelectedIndex
property again the SelectedIndexChanged
won't be fired because the selection is not changed actually. I have prepared a sample project for your reference.
I hope this information helps. Should you have further questions I would be glad to help.
