DateBox Methods

This section describes the members used to manipulate the widget.

beginUpdate()

Prevents the component from refreshing until the endUpdate method is called.

The beginUpdate and endUpdate methods allow you to apply several modifications to the component. After the beginUpdate method is called, the component does not update the UI until the endUpdate method is called. The usage of these methods prevents excessive component updating when changing multiple component settings at once.

blur()

Removes focus from the input element.

<preference name="KeyboardDisplayRequiresUserAction" value="false" />

After that, the focus() method will work as follows.
