In combo box once a value is selected there is no option to clear the selection. We can have an additional button outside the combo box to achieve the same.
This will require some additional coding.
Since this is a regular scenario why can't there be a property within the RadCombo Box that makes clear selection button visible next to the combo box drop-down button and does the task of clearing the selection?
Based on customer feedback: The RadFormDecorator decorates most native input controls, but does miss some, namely in ComboBox and ListBox. As this [the lack of decoration] is something advertently done, due to various issues in different browsers, we should thread carefully.
