RibbonControl.Items Property
Provides access to a Ribbon Control’s item collection.
Namespace: DevExpress.XtraBars.Ribbon
Assembly: DevExpress.XtraBars.v19.2.dll
Declaration
[Browsable(false)]
[XtraSerializableProperty(false, true, false)]
public RibbonBarItems Items { get; }Property Value
| Type | Description |
|---|---|
| RibbonBarItems | A RibbonBarItems object that represents the collection of bar items. |
Remarks
This collection stores bar items that can be used within the current RibbonControl. If you want to use a bar item within the Ribbon Control ensure that it’s added to the Items collection.
If a bar item is created at design time using the RibbonControl’s designer it’s automatically added to the Items collection. If a bar item is created in code, you need to add it to the collection manually or use one of the following methods of creating bar items that will add the created item to the collection:
- create items using the Create… methods provided by the Items collection (for instance, BarItems.CreateButton, BarItems.CreateMenu, RibbonBarItems.CreateButtonGroup, BarItems.CreateSplitButton, etc);
- create items using their constructors that have the manager parameter. Pass the object specified by the RibbonControl.Manager property as this parameter.
For more information on bar items, see Items and Item Links.
Example
This example demonstrates how to create a RibbonControl and RibbonStatusBar in code.
The RibbonControl contains one page (“Home”), two page groups (“File” and “File 2”) and three commands (bar items). The RibbonStatusBar contains two commands aligned to the left and right respectively.
When you create a Ribbon UI in code, ensure the following:
- All bar items are added to the
RibbonControl.Itemscollection. - All bar items have their BarItem.Id properties initialized to unique values.
using DevExpress.XtraBars.Ribbon;
using DevExpress.XtraBars;
private void Form1_Load(object sender, EventArgs e) {
// Create a RibbonControl
RibbonControl ribbon = new RibbonControl();
this.Controls.Add(ribbon);
// Assign the image collection that will provide images for bar items.
ribbon.Images = imageCollection1;
// Create a Ribbon page.
RibbonPage page1 = new RibbonPage("Home");
// Create a Ribbon page group.
RibbonPageGroup group1 = new RibbonPageGroup("File");
// Create another Ribbon page group.
RibbonPageGroup group2 = new RibbonPageGroup("File 2");
// Create a button item using the CreateButton method.
// The created item is automatically added to the item collection of the RibbonControl.
BarButtonItem itemOpen = ribbon.Items.CreateButton("Open...");
itemOpen.ImageIndex = 0;
itemOpen.Id = ribbon.Manager.GetNewItemId(); //Ensures correct runtime layout (de)serialization.
itemOpen.ItemClick += new ItemClickEventHandler(itemOpen_ItemClick);
// Create a button item using its constructor.
// The constructor automatically adds the created item to the RibbonControl's item collection.
BarButtonItem itemClose = new BarButtonItem(ribbon.Manager, "Close");
itemClose.ImageIndex = 1;
itemClose.Id = ribbon.Manager.GetNewItemId(); //Ensures correct runtime layout (de)serialization.
itemClose.ItemClick += new ItemClickEventHandler(itemClose_ItemClick);
// Create a button item using the default constructor.
BarButtonItem itemPrint = new BarButtonItem();
// Manually add the created item to the item collection of the RibbonControl.
ribbon.Items.Add(itemPrint);
itemPrint.Caption = "Print";
itemPrint.ImageIndex = 2;
itemPrint.Id = ribbon.Manager.GetNewItemId(); //Ensures correct runtime layout (de)serialization.
itemPrint.ItemClick += new ItemClickEventHandler(itemPrint_ItemClick);
// Add the created items to the group using the AddRange method.
// This method will create bar item links for the items and then add the links to the group.
group1.ItemLinks.AddRange(new BarItem[] { itemOpen, itemClose, itemPrint });
// Add the Open bar item to the second group.
group2.ItemLinks.Add(itemOpen);
// Add the created groups to the page.
page1.Groups.Add(group1);
page1.Groups.Add(group2);
// Add the page to the RibbonControl.
ribbon.Pages.Add(page1);
//...
// Create a status bar with two commands.
