TdxDiacriticStringComparisonMode Enum

Enumerates comparison modes for string data that contains characters with diacritic marks.

Declaration

TdxDiacriticStringComparisonMode = (
    Sensitive,
    Insensitive,
    Auto
);

Members

Name	Description
Sensitive	Default. String data search, filter, and sort operations always treat all character varieties with different diacritic marks as different characters. The TdxDiacriticStringOptions.NormalizationMode property value has no effect in this mode.
Insensitive	String comparison operations treat all character varieties with different diacritic marks as the same character. Insensitive string comparison is useful if you need less strict text search and filter criteria for the target language that uses diacritic marks. Note This mode may reduce overall application performance because diacritic-insensitive string normalization and comparison algorithms are more time-consuming.
Auto	The automatic string comparison mode for languages with diacritic marks. String data search, filter, and sort operations are diacritic-insensitive only for the languages listed in the Remarks section.

Remarks

All DevExpress data controllers^[1] and text field-based editors^[2] can interpret characters with different diacritic marks as different characters (default) or as the same character.

Note

TdxDiacriticStringComparisonMode is a scoped enumeration type. Use the type name together with a scope resolution token (. in Delphi or :: in C++Builder) followed by an enumeration value to refer to this value. For example, use TdxDiacriticStringComparisonMode.Auto (in Delphi) or TdxDiacriticStringComparisonMode::Auto (in C++Builder) to refer to the Auto value in code.
