The Expression editor
The Expression editor allows you to use VB operators and functions, while respecting a predefined syntax. You can identify
the properties that can be configured using VB expressions by the "tune" icon .
Expressions must reference the property name given in the app page. For example, to reference the main page, include the snippet MainPage in your expression. If you rename the main page to First Page, include the snippet FirstPage in your expression.
App. , and a list of available functions unfolds.
By default, when you use the Tab key in the expression editor, the system inserts a space in the expression.
To enable keyboard navigation using the Tab key, use the Ctrl + M shortcut on Windows, or the Ctrl + Shift + M shortcut on Mac OS X.
After you apply this shortcut, pressing Tab switches the focus to the next selectable item on the page.
To unlock the power of VB expressions in your app:
- Select the VB Expression Language checkbox when you create a new app.
- To edit the General properties of a control, or to configure an event rule, look for the "tune" icon
.
- For the desired property, click Open expression editor and start writing your VB expressions.
