# On Region Control Draw

> Customize region drawing with the On Region Control Draw event, which runs before FlexiCapture redraws a field region and exposes a drawing context.

## When it is launched

The script is launched prior to redrawing the region.

* If the **DrawDefault.Value** property is set to **true**, drawing the region will be cancelled.
* If the **DrawDefault.Value** property is set to **false**, the region will be redrawn.

By default, the value of the **DrawDefault** parameter is **false**.
