RegisterUserDefinedFunction Method

Registers a single Infragistics.Documents.Excel.CalcEngine.ExcelCalcFunction instance.

Syntax

C#

public bool RegisterUserDefinedFunction( 
   ExcelCalcFunction userDefinedFunction
)

Parameters

userDefinedFunction

User defined function instance to register

Return Value

Returns true if the type was registered successfully, else false if the registration failed

Remarks

Users can build custom functions used in formulas by sub-classing the Infragistics.Documents.Excel.CalcEngine.ExcelCalcFunction class. Once the derived class is instantiated it must be registered by using the RegisterUserDefinedFunction method before being available and referenced by a formulas. Users can build a library of functions packaged in an assembly and register all the functions within the assembly by using the RegisterUserDefinedFunctionLibrary method.
