Extending Properties

When developing your web flow, you can extend the properties of your web screens and widgets with a set of their native properties that you can handle. At runtime, those web screens and widgets translate to HTML elements and the extended properties are converted to HTML attributes and events. However, if necessary, you can add more attributes and/or events to implement specific behaviors in your screens.

For example, through the extended properties, you can add a tool tip to an expression: To do this simply add the title property to the Expression widget.

Name

The Properties can be any possible attribute that the HTML element can accept as specified in the HTML language reference. Service Studio does evaluate or validate any of the properties you add.

Service Studio provides you with a drop-down list with suggested properties, but you can also add a new one simply by typing its name in this column. The property names are strings.

If you type in the same extended property more than once for a specific element, if you use spaces, " or ' in the properties name, an error message is presented and the eSpace is not valid (An eSpace is valid when all expressions are correctly defined and the TrueChange operation issues no errors.).

Value

The values of the extended property can be:

empty and in this case, at runtime, the corresponding HTML tag is created as property = "property". For example, the nowrap property does not require a value, therefore nowrap = "nowrap" is added.
typed directly in the Extended properties;
you can use expressions, through the Expression editor.

For example, suppose that in the previous situation the tool tip must be evaluated at run-time (Entity is a local variable); you have to type the following in the Extended Properties section of the widget's Properties Pane:
