class RadioButton

Topic group Related topics

A single RadioButton on a form. The user may choose one from a set.

Syntax

[<oRef> =] new RadioButton(<container> [,<name expC>])

<oRef>

A variable or property—typically of <container>—in which to store a reference to the newly created RadioButton object.

The container—typically a Form object—to which you’re binding the RadioButton object.

An optional name for the RadioButton object. If not specified, the RadioButton class will auto-generate a name for the object.

The following table lists the common properties, events, and methods of the RadioButton class:

Description

Use a group of RadioButton objects to present the user a set of multiple choices, from which they can choose only one.

Each set of choices on a form must have the same group property. If there is only one group of RadioButtons on a form, the group can be left blank. You may use any string or number as the group property.

You may also use true and false in the group property to create RadioButton groups. Use true for the first button in each RadioButton group, and false for the rest. For example, if you create seven RadioButtons and set the group property of the first and fourth RadioButton to true, the first three buttons form one group, and the last four form another. The two groups are independent; the user can select one button in the first group and one button in the other.
