ParameterAttributes Enum

Lists parameter attributes.

Namespace: DevExpress.Spreadsheet.Functions

Assembly: DevExpress.Spreadsheet.v21.2.Core.dll

Declaration

public enum ParameterAttributes

Members

Name Description
Required

The parameter is mandatory. A missing parameter results in a user warning dialog.

Optional

The parameter is not required. If it is missing, the function still compiles and evaluates. Note that optional parameters should come after all required parameters.

OptionalUnlimited

Any number of parameters which are not required. Note that the total number of parameters should not exceed 255 and the optional unlimited parameter should be the final parameter.

Remarks

Specify the parameter attribute for the ParameterInfo objects in the IFunction.Parameters array to create a function signature. A function signature provides parameter validation when a function is evaluated.
