ClFindComponent

To find another component under a component or form, clFindComponent is used. This method allows you to search for a specific named subcomponent. This allows making changes to the properties of the found component.

MyForm.clFindComponent(xObjectName : String)

Within this feature, a string parameter is accepted, and this parameter is the name of the variable.

Example:
In the example, we can determine which of the multiple buttons created using the clSender feature we clicked on and change the button text using the clFindComponent property.
