Telerik script language provides five intrinsic (or "built-in") objects. They are the Fields, Parameters, PageNumber, PageCount, and ReportItem objects.
The Fields collection represents the set of fields specified by the report data source plus any additional calculated fields that you create. After you create a data source for a data item (Report, Table, Crosstab, List, Chart), the field collection appears in the Data Explorer toolbox.
- returns the value of the field ProductID in the current data
scope instance. If the data source does not contain the
referenced column, error is thrown. If the report has no data
source set, the expression result is null (Nothing)
If the data source field name is not a valid name in terms of programming languages (contains spaces, punctuation marks, etc.) enclose its name in square brackets, for example =Fields.[My Column]; Because brackets are special characters, you must use a back slash ('\') to escape the bracket, if it is part of a data field name. For example, a data field named Field would be referenced as Fields.[Field\[1\]].
Another option of accessing the values in the fields collection is the global function Fields(fieldName).
represents the collection of report parameters, each of which can be single-value or multi-value. See Adding Parameters to Report.
- returns the value of the report parameter with name Product;
=Parameters.Product.Label - returns
the label of the report parameter with name Product.
Another option for accessing the report parameters' collection is the global function Parameters(parameterName).
