Tip

For more info, design guidance, and code examples, see Buttons.

Open the WinUI 2 Gallery app and see the DropDownButton 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

The chevron is a visual indicator that a flyout is available with a menu of options. The DropDownButton has the same behavior as a standard Button with a flyout (only the appearance is different).

For more info and examples, see Buttons.

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.
