You can also handle the ContextItem.Click event to respond to a click on a particular button.

csharp

private void listBoxControl_ContextButtonClick(object sender, DevExpress.Utils.ContextItemClickEventArgs e) {
    if (e.Item.Name=="Delete") {
        var listBoxControl = (DevExpress.XtraEditors.ListBoxControl)sender;
        listBoxControl.Items.Remove(e.DataItem);                
    }            
}

Private Sub listBoxControl_ContextButtonClick(ByVal sender As Object, ByVal e As DevExpress.Utils.ContextItemClickEventArgs)
    If e.Item.Name="Delete" Then
       Dim listBoxControl = DirectCast(sender, DevExpress.XtraEditors.ListBoxControl)
       listBoxControl.Items.Remove(e.DataItem)
    End If
End Sub
