# TCustomRadioGroup.OnItemEnter

Event handler signalled when a radio button in the group receives focus.

## Declaration

Source position: extctrls.pp line 779

`public property TCustomRadioGroup.OnItemEnter : TNotifyEvent read FOnItemEnter write FOnItemEnter;`

## Description

OnItemEnter is a TNotifyEvent property that implements the event handler signalled when a radio button in the group receives focus. It occurs when the value in ItemIndex has been changed. An application must implement and assign an object procedure to the property to respond to the event notification. The Sender argument contains the radio button which is selected in the control.

OnItemEnter is signalled (when assigned) from the ItemEnter method.

Remark: | OnItemEnter was added in LCL version 2.2, and should be used in place of the OnEnter event handler. This change is Delphi compatible.

## Version info

Added in LCL version 2.2.0.
