DevExpress data-aware controls provide a complete set of options to format display values.
Standard or Custom Format Specifiers
Allows you format numeric and date-time values according to predefined or custom patterns. For instance, a numeric value can be represented as a currency amount or a hexadecimal value, using scientific notation, etc. A date-time value can be represented in the standard Short Date. Long Date or Full Date-Time form.
DevExpress data-aware controls provide events that allow you to manually specify the display text. For instance, the DXGrid provides the GridControl.CustomColumnDisplayText event allowing you to provide custom text for any data cell. Editor controls shipped within the DXEditors Library provide the BaseEdit.CustomDisplayText event, which enables you to display a custom string within the editor.
