WorkbookFunctions.OverrideFunction(String, ICustomFunction, Boolean) Method

Replaces the built-in function specified by its name with a custom function.

Namespace: DevExpress.Spreadsheet.Functions

Assembly: DevExpress.Spreadsheet.v19.2.Core.dll

Declaration

C#

void OverrideFunction(
    string name,
    ICustomFunction function,
    bool skipIfExists
)

VB.NET

Sub OverrideFunction(
    name As String,
    function As ICustomFunction,
    skipIfExists As Boolean
)

Parameters

Name	Type	Description
name	String	A name of the function to replace.
function	ICustomFunction	An ICustomFunction descendant that is the custom function.
skipIfExists	Boolean	true, to cancel the function replacement if the built-in function with the specified name exists; otherwise, false.

Remarks

Use this OverrideFunction method overload with the skipIfExists parameter set to true to add a custom implementation of the built-in function not currently supported by the Spreadsheet Suite. When the function becomes available in future versions, it won’t be replaced, so the native implementation will be used instead of a custom one.
