# Control Object Properties

Auto | Signal On All Changes

## Description

Signal on all changes

When set, the control will generate a 'Change' event whenever its value changes as opposed to the default Off state where the control will only generate the change event when losing focus.

Possible values are:

0 | Only signal change when exiting the control or on special event such as double click/Enter. (Default)
1 | Signal all changes to the value of the control regardless of why the change occurred.
2 | Signal all changes done by the user but not done by the program. (The ability to only receive user changes was added in PxPlus v7.00.)

## Default

0 - Only signal change when exiting the control or on special event such as double click/Enter
