The conversions between the 'string' and the ValueType by default are done using built in conversion logic. You can override the conversion logic by setting the ValueToDisplayTextConverter and ValueToTextConverter. ValueToTextConverter is used when the editor is in edit mode where as ValueToDisplayTextConverter is used when the editor is not in edit mode.
Note: An editor can edit values of types other than 'string'. For example, a XamTextEditor can edit values of types DateTime. You can specify the type of values being edited by the editor using the Infragistics.Windows.Editors.ValueEditor.ValueType property.
Although the built-in default conversion logic should be sufficient for most situations, you may want make use of this functionality to provide custom logic for converting user input into value type object. Examples where this would be needed are if you are editing custom objects where the built-in conversion logic would not know how to convert text into custom object type. Or you want to support entering certain symbols in the text that signify certain aspect of the value - for example you want 'k' in '2k' to be interpreted as 1000 magnitude, or +1d to be interpreted as tomorrow's date when editing DateTime.
Note that not all derived editors support or utilize ValueToTextConverter. Editors where value to text conversions are performed intrinsically, such as Infragistics.Windows.Editors.XamComboEditor where both the value and text are retrieved from the selected item, do not support ValueToTextConverter.
