# On Text Field Validating

> Validate text field edits with the On Text Field Validating event in FlexiCapture; set CanApply to false to undo or accept the user's input.

## When it is launched

The script is launched when the control is validating the user editing of a text field, e.g. when trying to choose the value from suggestions or when the control loses focus.

* If the **CanApply.Value** property is set to **true**, the user input will be validated after the script execution.
* If the **CanApply.Value** property is set to **false**, the user editing will be undone.

By default, the value of the **CanApply** parameter is **true**.
