Radio Button List

The Radio Button List items style is useful when there is a need to select a single option from a short list.

For example, the Ship Via Company Name field on the Orders edit form uses Lookup item style by default. A lookup may be useful with a large number of records to choose from. However, there are only three shipping companies in the Northwind database, making a lookup redundant. Let’s change this lookup into a radio button list.

Data Value Field ShipperID
Data Text Field CompanyName

Press OK to save the field, and press Browse on the tool bar. Navigate to Orders page and edit a record.

Ship Via Company Name field is now rendered as a radio button list. The “N/A” option appears because the field is not mandatory. If more shippers are added to the Shippers table, then more options will be available in the list.
