Defines a parameter to pass to a custom function.
Namespace: DevExpress.Spreadsheet.Functions
Assembly: DevExpress.Spreadsheet.v18.2.Core.dll
Declaration
Remarks
Use the IFunction.Parameters property to specify regular and optional parameters and their types. This array of parameter information defines the function signature. When a custom function is called, the parameters are checked for compliance with the array of ParameterInfo objects. If inconsistencies are found, a warning message box is shown.
Parameters should match the ParameterInfo objects in type and attributes. In addition, all the required parameters should come first, followed by optional parameters. A ParameterInfo object that corresponds to the optional unlimited number of parameters should be the final item in the array.
