Your company assigns three possible credit ratings to customers: Poor, Good, and Excellent (represented numerically by 1, 2, and 3). The DBA has just added a RATING column to the CUSTOMERS table and has asked you to add an item to your form so that credit ratings can be recorded. To restrict data entry clerks to one of these three values, you decide to create a radio group for the Rating item. With the items node of the Customers block selected in the Object Navigator, you click Create. You then open the Property Palette for the new item and set properties as follows:
Name: RATING
Item Type: Radio Group
Data Type: Number
Column Name: Rating
Canvas: CUSTOMER_CV
You open the CUSTOMER_CV canvas in the Layout Editor, but the Rating item does not appear.
How can you get the Rating item to appear on the canvas?
A.
Create a radio button for the radio group.
B.
Set the Visible property of the Rating item to Yes.
C.
Delete the radio group and create it in the Layout Editor because a radio group that is created in the Object Navigator will not appear on a canvas.
D.
Change the width of the Rating item because the default width of a radio group is 0, so it does not appear on the canvas.
