Assembly : DevExpress.Spreadsheet.v25.2.Core.dll

NuGet Package : DevExpress.Spreadsheet.Core

Declaration

C#
VB.NET

csharp

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

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.
