You can automate the sourcing of content for tables and picker controls by defining sources for the values that populate the tables and controls at run time. For example, in a delivery form, you can configure a radio button control group to display the values from the D_CustomerDeliveryAddresses data page so that the customer can choose the most convenient option for a particular order.
You can configure a data source for your UI element at the following levels:
- A property. For more information, see Specifying a data source directly in a property.
Note: The term
propertyis used in Dev Studio context. To refer to
propertiesin App Studio, we use the term
- A picker control. For more information, see Specifying a data source in a control.
The UI Gallery landing page contains working examples of the picker controls. For more information, see Accessing the UI Gallery.
- A table. For more information, see Creating a table layout with code optimization.
- Levels of configuration for data sources
UI elements can have different sources of data. You can configure the available options at the level of a pricker control, a property, or a table, depending on your needs.
- Data page as a source of data
You can tie a data page to a UI element of you application to access data from a range of sources on demand. For example, you can configure a field for customer information to draw data from the D_Customer data page, and not directly from the database.
- Report definition as a source of data
You can populate your UI elements such as tables, drop-downs, and auto complete controls with data that the report definition query returns. For example, you can source data for an autocomplete control from the results of a report definition to display service provider names and locations.
- Specifying a data source in a control
Improve the maintainability of your application by defining sources for the values that populate controls. For example, you can configure an autocomplete control to display a list of employee names and their employment types that are sourced from a data page.
- Specifying a data source directly in a property
Make the development process more convenient by defining the source of data for a control directly in a property that populates the control with values at run time. For example, you can configure a drop-down menu to display the contract type property.
