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 property is used in Dev Studio context. To refer to properties in App Studio, we use the term fields.
• 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.

• Sources of data at a particular configuration level

  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.
