Crystal Reports for Eclipse Designer Guide

To specify single or range values

  1. In the "Field Explorer" view, right-click Parameters, and then click New.
  2. Enter a name for the parameter, and then click Enter.
  3. In the "Properties" view, select the appropriate Type from the list, and enter prompting text.
  4. In the Value Range Kind property, choose Discrete or Range.
    • If you select Discrete, the parameter field will accept single values (rather than ranges of values).
    • If you select Range, when you are prompted for parameter values, you can enter a start value and an end value. For example, if you enter the values "5" and "10", the range is 5-10, and a report that uses this parameter for record selection will display all records with values between 5 and 10. This also works for string parameter fields. With a start value of "A" and an end value of "E", a report that uses this parameter for record selection will display all records within an alphabetical range of A-E.

    Note: If the Allow Multiple Values and the Discrete options are selected, the parameter field will accept multiple single values. In this case, you can enter more than one value, but these values will be evaluated individually and will not be interpreted as a range. If the Allow Multiple Values and Range options are selected, the parameter field will accept multiple ranges.
  5. If applicable, enter values in the Min Length and Max Length properties to designate the length of the field.
    • For a String, Currency, or Number data type, options for entering the Min Length and Max Length appear.
    • For a Date, Time, or Date Time data type, options for entering the Start and End appear.
    • For a Boolean data type, no options are available.
