# TBasicActionLink.Change

Executed whenever the Action is changed.

## Declaration

`protected procedure TBasicActionLink.Change; virtual;`

## Description

Change is executed whenever the action changes. It executes the OnChange handler, if one is assigned.

Component programmers may decide to override the Change procedure in descendent classes to perform aditional actions when the properties of the action changes.
