The easiest way to create a ribbon commanding UI for a drawing view is to use the NDrawingViewWithRibbon widget or drop the NDrawingViewWithRibbonControl to a form/window using the Visual Studio Designer. You can then use the following approaches to modify the ribbon:

1. Hiding Ribbon Tab Pages and Ribbon Groups

To hide a an element from the ribbon use the corresponding Get... method of the NDrawingViewWithRibbon or the NDrawingViewWithRibbonControl class and set its Visibility property to Collapsed:

• GetApplicationMenu - gets the ribbon application menu.
• GetRibbonTabPage - gets the ribbon tab page with a given title.
• GetRibbonGroup - gets the ribbon group with a given groupTitle in the tab page with a specified pageTitle.
• GetRibbonSearchBox - gets the ribbon search box.
• GetRibbonQuickAccessToolbar - gets the ribbon quick access toolbar.
• GetStatusBar - gets the status bar.

The following code snippet hides the "Mailings" ribbon tab page and the "Zoom" ribbon group of the "View" ribbon tab page:

// Hide the "Mailings" ribbon tab page
nDrawingViewWithRibbonControl1.GetRibbonTabPage(NDiagramRibbonBuilder.TabPageMailingsName)
    .Header.Visibility = ENVisibility.Collapsed;

// Hide the "Zoom" ribbon group of the "View" ribbon tab page
nDrawingViewWithRibbonControl1.GetRibbonGroup(NDiagramRibbonBuilder.TabPageViewName, NViewTabPageBuilder.GroupZoomName)
    .Visibility = ENVisibility.Collapsed;

2. Removing Commands

To hide all widgets associated with specific commands from the commanding UI, use the RemoveCommands method of the drawing view with ribbon. For example, the code snippet below removed the Open, Save and Save As commands and hides the widgets associated with them from the ribbon:

// Create an array of commands to remove
NCommand[] commandsToRemove = new NCommand[] {
    NDrawingView.OpenCommand,
    NDrawingView.SaveAsCommand,
    NDrawingView.SaveCommand
};

NDrawingViewWithRibbon drawingViewWithRibbon = new NDrawingViewWithRibbon();
drawingViewWithRibbon.RemoveCommands(commandsToRemove);

You can also create NOV Diagram ribbon commanding UI using the NOV Diagram ribbon builder. This gives you greater flexibility and more ways to customize the NOV Diagram ribbon:

NDiagramRibbonBuilder ribbonBuilder = new NDiagramRibbonBuilder();
NWidget drawingViewWithRibbon = ribbonBuilder.CreateUI(drawingView);

1. Modifying Ribbon Group Builders Collection

If you want to remove a given ribbon tab page, you can easily do so by using the Remove method of the TabPageBuilders collection of the diagram ribbon builder. To remove a ribbon group from a tab page, you should use the Remove method of the RibbonGroupBuilders collection of the ribbon group builder.

The names of all diagram ribbon tab pages are exposed as constants in the NDiagramRibbonBuilder class. Each of the tab page builders exposes as constants the names of its ribbon group builders. The following piece of code demonstrates how to remove the "Editing" ribbon group of the "Home" tab page of the diagram ribbon:

NRibbonTabPageBuilder homeTabBuilder = ribbonBuilder.TabPageBuilders[NDrawingRibbonBuilder.TabPageHomeName];
homeTabBuilder.RibbonGroupBuilders.Remove(NHomeTabPageBuilder.GroupEditingName);

In order to add or insert your own ribbon group builders, you can use the Add or Insert methods of the RibbonGroupBuilders collection respectively.

NRibbonTabPageBuilder homeTabBuilder = ribbonBuilder.TabPageBuilders[NDrawingRibbonBuilder.TabPageHomeName];
homeTabBuilder.RibbonGroupBuilders.Insert(0, new CustomRibbonGroupBuilder());

2. Custom Ribbon Group Builders

To create a custom ribbon group builder you should create a class, which inherits NRibbonGroupBuilder:

public class CustomRibbonGroupBuilder : NRibbonGroupBuilder
{
    public CustomRibbonGroupBuilder()
        : base("Custom Group", NResources.Image_Ribbon_16x16_smiley_png)
    {
    }

    protected override void AddRibbonGroupItems(NRibbonGroupItemCollection items)
    {
        // Add the "Copy" command
        items.Add(CreateRibbonButton(NResources.Image_Ribbon_32x32_clipboard_copy_png,
            Nevron.Nov.Presentation.NResources.Image_Edit_Copy_png, NDrawingView.CopyCommand));

        // Add the custom command
        items.Add(CreateRibbonButton(NResources.Image_Ribbon_32x32_smiley_png,
            NResources.Image_Ribbon_16x16_smiley_png, CustomCommand));
    }
}
