In your web screens you can create input fields that hold the data typed by the end-user. This data is then stored in a variable that you can handle in your application. This behavior is implemented by the Input widget.
If the end-user does not specify a value and leaves the input empty, the widget variable is set to the null value specified in the Null Value property of the widget or, if empty, the null value of the data type.
Likewise, if the end-user types a value that is incompatible with the variable data type (e.g. an invalid date), the variable is set to the null value of the widget or, if empty, the null value of the data type. The typed value is stored in the Input widget runtime property with the same name.
You can use the default null value or specify a null value that is more suitable for your application by simply setting the Null Value property.
At development time, the Input widget is displayed on the Content Canvas as an empty box.
