ICustomFunctionDescriptionsRegisterService Interface

Provides captions and text descriptions for the Function Argument dialog invoked for the custom function (UDF).

Namespace:DevExpress.Spreadsheet.Functions
Assembly:DevExpress.Spreadsheet.v18.1.Core.dll

Expanded Syntax

Expanded Remarks

To get the service of the ICustomFunctionDescriptionsRegisterService type, use the GetService<T> method of the workbook.

To specify function and argument descriptions for a certain custom function, call the RegisterFunctionDescriptions method. The method requires a CustomFunctionArgumentsDescriptionsCollection object that is the collection of items containing the type and description for each argument. The order of argument descriptions in the collection is the same as the order of arguments in the function signature.

Expanded Example

This example illustrates the use of the ICustomFunctionDescriptionsRegisterService service for the SPHEREMASS custom function defined in the WinForms SpreadsheetControl API - Part 2 example available in the DevExpress Code Examples database at http://www.devexpress.com/example=E4832.
