FieldExpressionAttrs Enumeration

Attributes used when resolving field reference expressions. Each of these attributes corresponds to a modifier flag character. See the ExpressionParser class for more information about field references.

• [$keyname] - DisplayText - Use the field's display text rather than its raw value (obtained via DisplayTextGet(DispTextFlags)).
• ['keyname] - AnsiQuote - AnsiQuote the value using AnsiQuote(String).
• [`keyname] - DoubleQuote - Enclose the field value in double-quote '"' characters (this is a back-tick character).
• [#keyname] - Numeric - The value is a numeric value and should be rendered as zero "0" if the value is null/empty.
• [<keyname] - UseOldValue - Use the OldValue if the field is dirty.
• [&keyname] - UseCaption - Use the field's Caption instead of its value.
• [?keyname] - EscapeForUrl - The field's value should be escaped for use in a URL using ForUrl(String).
• [@keyname] - EscapeForHtml - The field's value should be escaped for use in HTML using ForHtml(String).
• [^keyname] - ApplyDefault - Use the field's DefaultValue if the field's value is null/empty.
• [+keyname] - EscapeForXML - The field's value should be escaped for use in XML using ForXml(String).
• [*keyname] - RawValue - Use the field's raw value (obtained via Value), implied if no other option specified.
• [~keyname] - ClientElement - Renders as a javascript expression accessing the field. Often combined with either '$' or '*' attributes to obtain the client-side display or raw values respectively.
• [:keyname] - Optional - Value is optional and should default to zero or empty string, as appropriate.
• [-keyname] - Guid - The value is a GUID value and should be rendered as the zero GUID "{00000000-0000-0000-0000-000000000000}" if the value is null/empty.
