VB.NET

'' First, the button items are created:
Dim button1 As RibbonButton = New RibbonButton()
button1.Text = "Button1"

Dim button2 As RibbonButton = New RibbonButton()
button2.Text = "Button2"

'' These are then added to a row:
Dim row As RibbonRow = New RibbonRow()
row.RowItems.Add(button1)
row.RowItems.Add(button2)

'' This row is added to a panel source, which is then added to a panel:
Dim panelSource As RibbonPanelSource = New RibbonPanelSource()
panelSource.Title = "Panel1"
panelSource.Rows.Add(row)

Dim panel As RibbonPanel = New RibbonPanel()
panel.Source = panelSource

'' Last, the panel is added to a tab, which is added to the ribbon:
Dim tab As RibbonTab = New RibbonTab()
tab.Title = "Tab1"
tab.Panels.Add(panel)

Dim ribbon As RibbonControl = New RibbonControl()
ribbon.Tabs.Add(tab)

// First, the button items are created:

// Last, the panel is added to a tab, which is added to the ribbon:
RibbonTab tab = new RibbonTab();
