TdxLayoutRadioButtonItem Class

A radio button in the layout control.

Declaration

TdxLayoutRadioButtonItem = class(
    TdxCustomLayoutCheckableItem
)

Remarks

The layout radio button is the auxiliary item that allows you to replace standard and DevExpress radio buttons that have no full compatibility with the layout control and speed up draw operations in the control and thus increase an application’s performance.

This class initializes the Checked and TabStop property values to False and extends the TdxCustomLayoutCheckableItem ancestor class with the members that allow users to access a layout radio button caption’s settings (CaptionOptions) and group layout radio buttons (GroupIndex).

Note

A TdxLayoutRadioButtonItem class instance has no backward compatibility with TRadioButton and its descendants.
