Refer to the following code for how to get the unique ID of a selected shape in the code behind.

```
private void Editor_ItemSelected(object sender, ItemSelectedEventArgs args)
{
String currentShapeID = args.PenSettings.ShapeID;
}
```

## Masked Entry

### Password character support for unmasked fields

This feature allows users to add password characters when the mask in the [Xamarin.Forms Masked Entry](https://www.syncfusion.com/xamarin-ui-controls/xamarin-masked-entry)
 control is not defined.
