Examples

Tip

For more info, design guidance, and code examples, see Breadcrumb bar.

Open the WinUI 2 Gallery app and see the BreadcrumbBar in action.

The WinUI 2 Gallery app includes interactive examples of most WinUI 2 controls, features, and functionality. Get the app from the Microsoft Store or get the source code on GitHub.

Remarks

Tip

For more info, design guidance, and code examples, see Breadcrumb bar overview.

A BreadcrumbBar provides the direct path of pages or folders to the current location. It is often used for situations where the user's navigation trail (in a file system or menu system) needs to be persistently visible and the user may need to go back to a previous location.

If the app is resized so that there is not enough space to show all the nodes, the breadcrumbs collapse and an ellipsis replaces the leftmost nodes. Clicking the ellipsis opens a flyout to show the collapsed nodes.

Control style and template

You can modify the default Style and ControlTemplate to give the control a unique appearance. For information about modifying a control's style and template, see XAML styles. The default style, template, and resources that define the look of the control are included in the generic.xaml file. For design purposes, generic.xaml is installed with the WinUI (Microsoft.UI.Xaml) NuGet package. By default, this location is \Users\<username>\.nuget\packages\microsoft.ui.xaml\<version>\lib\uap10.0\Microsoft.UI.Xaml\Themes\generic.xaml. Styles and resources from different versions of WinUI might have different values.

XAML also includes resources that you can use to modify the colors of a control in different visual states without modifying the control template. Modifying these resources is preferred to setting properties such as Background and Foreground. For more info, see the Light-weight styling section of the XAML styles article.
