Custom Filter Function Properties
Each Custom Filter Function has the following properties:
A name for the filter function that will be displayed to the end users. Required.
A description of the function.
To support multi-language functionality, if the filter function’s name or description can be prepended with _wrFunctionId. If this ID matches the ID of any element in the language files, then the string of that language element will be displayed to the user instead of the function name/description in the Admin Console. For more information see Multi-Language Support.
Determines the data type that the filter function should be available for. Either Date, String, Integer or Decimal.
The order the filter function will appear among other filter functions of the same type. Functions with a lower number will appear higher on the list. If two functions have the same list value they will display in alphabetic order.
All of the built in filter functions start with list value 100 or greater.
A semicolon-separated list of any DLLs that need to be referenced by the Custom Filter Function. The DLLs must be present in the bin folder of the Exago Web Application, Scheduler Services, and the Web Service API if applicable. This folder can be found in the installation directory of the respective component.
System.dll does not need to be listed as a reference as it is already available.
A semicolon-separated list of any namespaces that need to be referenced by the Custom Filter Function.
The program code for your Custom Filter Function. The code must return the data type that was set in the Filter Type setting.
Parameters may be referenced within custom functions by placing their name between @’s. For example, @[email protected]
Click the Test custom code execution icon to verify that the code properly compiles.
