Can someone point me to an example of an unbound multicolumncombobox, e.g. adding items manually? I found an example
but this refers to properties which do not seem to exist (e.g. MultiColumnComboBoxElement and EditorControl).
2. In a databound multicolumncomboBox, when the user uses the drop-down, the drop-down appears with a transparent background, so you can see the elements rendered under it as part of the text... this makes it almost impossible to read. Is there a way to remove this transparency? I do not see a property. Is there a reason why this control is designed this way as opposed to being like a standard drop-down combo box?
