                                  • Hi Guys

                                    I have implemented some custom function operators which work fine. However you are unable to add them to FunctionOperatorHelper because functionInfoStaticDict is not exposed as a Property. This appears to be a bit of an oversight since my functions appear in the expression editor for (say) a CalculatedField in an XAF Report but unlike built in functions, no help or standard template is provided.

                                    If functionInfoStaticDict was exposed as a ReadOnly static property then I would be able to add the relevant help info if I wanted to.

                                    Best wishes

                                    John

                                  Hi John,

                                  There is no need to add custom function operators to this dictionary, because it contains information about built-in functions only. A custom function can provide additional information about itself by implementing the following interfaces: ICustomFunctionOperator, ICustomFunctionOperatorFormattable and ICustomFunctionOperatorBrowsable. Please refer to the Implementing Custom Functions article for details. If this does not help, please provide us with a small sample project demonstrating the issue.

                                  Thank you Michael
