Remarks

This class represents a single item displayed in the radio group control. The collection is represented by the RadioGroupItemCollection object.

Individual items can be accessed via the collection’s RadioGroupItemCollection.Item property using index notation.

C#

using DevExpress.XtraEditors.Controls;

// Create five items.
object[] itemValues = new object[] {10, 11, 12, 13, 14};
string [] itemDescriptions = new string [] {"Circle", "Rectangle", "Ellipse", "Triangle", "Square"};
for(int i = 0; i < itemValues.Length; i++) {
    radioGroup1.Properties.Items.Add(new RadioGroupItem(itemValues[i], itemDescriptions[i]));
}
//Select the Rectangle item.
radioGroup1.EditValue = 11;

VB.NET

Imports DevExpress.XtraEditors.Controls

' Create five items.
Dim itemValues As Object() = New Object() {10, 11, 12, 13, 14}
Dim itemDescriptions As String() = New String () {"Circle", "Rectangle", "Ellipse", "Triangle", "Square"}
Dim i As Integer = 0
Do While i < itemValues.Length
    radioGroup1.Properties.Items.Add(New RadioGroupItem(itemValues(i), itemDescriptions(i)))
    i += 1
Loop
'Select the Rectangle item.
radioGroup1.EditValue = 11
