RadRibbonBar: Add an option to scroll the button items in backstage view
It would be good to have any indication that there are more button items in the backstage view. Currently, RadRibbonBar neither shows scrollbars, no overflow button

Hello, Kun,

Thank you for reporting this.

Please refer to the following code snippet demonstrating a sample approach how to add scrollable button items in the backstage view.

public RadForm1()
{
    InitializeComponent();
    this.radRibbonBarBackstageView1.SizeChanged += radRibbonBarBackstageView1_SizeChanged;
}
 
private void radRibbonBarBackstageView1_SizeChanged(object sender, EventArgs e)
{
    BackstageViewElement backstageViewElemet = radRibbonBarBackstageView1.BackstageElement;
    BackstageItemsPanelElement itemsPanel = backstageViewElemet.ItemsPanelElement;
    item.MinSize = new System.Drawing.Size(200, itemsPanel.Size.Height - 10);
}
 
void RadForm1_Load(object sender, EventArgs e)
{
    BackstageViewElement backstageViewElemet = radRibbonBarBackstageView1.BackstageElement;
   
    BackstageItemsPanelElement itemsPanel = backstageViewElemet.ItemsPanelElement;
 
    RadScrollablePanel p = new RadScrollablePanel();
    RadHostItem host = new RadHostItem(p);
    host.StretchHorizontally = true;
    host.StretchVertically = true;
    p.Dock = DockStyle.Fill;
    for (int i = 0; i < 10; i++)
    {
        RadButton b = new RadButton() { Text = "Test" + i };
        b.Dock = DockStyle.Top;
        p.Controls.Add(b);
    }
     
    item.Children.Add(host);
    itemsPanel.Items.Add(item);
    this.radRibbonBarBackstageView1.BackstageViewOpened += radRibbonBarBackstageView1_BackstageViewOpened;
}
 
BackstageButtonItem item = new BackstageButtonItem();
 
private void radRibbonBarBackstageView1_BackstageViewOpened(object sender, EventArgs e)
{
    BackstageViewElement backstageViewElemet = radRibbonBarBackstageView1.BackstageElement;
    BackstageItemsPanelElement itemsPanel = backstageViewElemet.ItemsPanelElement;
