The SeparatorChar property is used to separate items in the edit value and the resultant text displayed in the edit box.
You can set a CheckedComboBoxEdit control's value via the CheckedComboBoxEdit.SetEditValue method. The value being assigned must specify a string that concatenates values (strings) of items to be checked. Values in the resultant string must be separated using the separator character specified by the SeparatorChar property, followed by a SPACE character.
The SeparatorChar property is not in effect when the control is bound to a bit field. When the control is bound to a bit field, flags in the text displayed in the edit box are delimited, using the character specified by the current thread's System.Globalization.TextInfo.ListSeparator property.
