|Expression||Expression||WideString||Expression, the result of evaluating the expression will be printed (except if it's an aggregate)|
|Data Type||DataType||TRpParamType||Used for formatting output, if you specify a data type and the expression value is NULL it's replaced with the type equivalent for formating, this is specially usefull for numeric values|
Formating mask, the value to print will be formated with this string, depending on the data type of the value the string have diferent meanings.
For example for a DateTime value you can use the format string: 'dd/mm/yyyy hh:nn:ss', for a number: '###,###0.00', where the , says the use of thousand separator, the 0 are required format positions and # are not required format positions.
The engine will use FormatStr function, see documentation, but if the first character is a *, the FormatNum function will be used (only for numbers), using the mask without the first char.
|Multi page||MultiPage||Boolean||If true, then the print value (usually a string) will print in diferent pages if needed, usually you set autoexpand and autocontract to true in the parent section and word wrap property to true|
|Print Null||PrintNulls||Boolean||If true, the numbers with 0 value will not be printed|
|Identifier||Identifier||String||If you assign a identifier string, you can get the effective value of this TRpExpression from any expression inside report, so the identifier is included in the expression evaluator namespace, this is useful when working with aggregate fields and, for example, sum two aggregate values at a group footer.|
|Agg. Group||GroupName||String||For Aggregate=Group indicates wich is the group that initializes the aggregate value|
Expression with the initial value if an aggregate have been selected, note the Sum aggregate type is available to sum strings so you must place a '' value to sum the strings
|P.Only One||PrintOnlyOne||Boolean||If the value is repeated and the section have not changed, will print only once, this is usually useful to group without adding group header/footers, that is ordering the dataset and print only when the field value changes|
|Single line||SingleLine||Boolean||Will force printing of text in a single line even if it contains line feeds.|
|F.Rotation||FontRotation||Angle||Rotation angle in degrees for the text. Rotation in reverse clock wise, internally stored as an integer in degrees*10 scale.|
|Internal component name||TRpExpression|
