All Ribbon Tabs contain Item Groups that can keep many Items together. When a new Tab is added in the C1Ribbon control, it already has a default Group. If the user wants to add more Item Groups, then it can be done by clicking the Actions menu of the floating toolbar of the Ribbon Tab. The user can also add a Group with the help of the RibbonGroup Collection Editor of Ribbon Tab in Properties window.

The image below depicts a Ribbon Item Group.

Adding Groups to Tabs at Design Time

You can add Groups to tabs in the designer using the Tab Floating ToolBar. Refer this topic for more information about floating toolbars. The user can also add groups to the tabs using Groups property of RibbonTab in the Properties window. Clicking on the ellipsis next to the Groups Property launches the RibbonGroup Collection Editor. For more explanation about the Collection Editors, refer this topic.

Adding Groups to Tabs through Code

The user can also add the Ribbon Item Group programmatically with the Groups property of RibbonTab class and the Text property of RibbonGroup class. This is shown in the code below:

'[ホーム]タブにグループを追加します
Dim fontStyle As New RibbonGroup()
'グループにラベルを付けます
fontStyle.Text = "Font"
homeTab.Groups.Add(fontStyle)

//「フォント」という名前のグループを「ホーム」タブに追加します
RibbonGroup fontStyle = new RibbonGroup();
fontStyle.Text = "Font";
homeTab.Groups.Add(fontStyle);
fontStyle.HasLauncherButton = true;

Adding Launcher Button

A user can add a dialog box launcher button to the Ribbon group using the floating toolbar as shown in the image below.

You can also add a launcher button using the HasLauncherButton and LauncherEnabled properties of RibbonGroup in the Properties window. Further, you can also add a launcher button programmatically using the HasLauncherButton property of the RibbonGroup class as shown in the code snippet below:

'ランチャーボタンを追加します
fontStyle.HasLauncherButton = True

//ランチャーボタンを追加します
fontStyle.HasLauncherButton = true;
