T:Windows.UI.Xaml.Controls.CommandBarOverflowPresenter |
winrt class |
Displays the overflow content of a CommandBar.
See Remarks
You don't typically declare object elements for CommandBarOverflowPresenter in XAML. There are no properties that a CommandBarOverflowPresenter can set in XAML syntax and there's no reason to declare a CommandBarOverflowPresenter as a resource.
The main purpose of the CommandBarOverflowPresenter class is to be the default internal presenter for the SecondaryCommands value of a CommandBar. You extend presentation behavior of the CommandBarOverflowPresenter by setting a value for the CommandBarOverflowPresenterStyle property of the CommandBar. The Style you declare that fills the CommandBarOverflowPresenterStyle property must specify TargetType="CommandBarOverflowPresenter". The properties that can be styled are the dependency properties of the base ItemsControl class or Control class, such as FontSize or Padding, or base element properties such as FrameworkElement.Margin that the CommandBarOverflowPresenter class inherits.
CommandBarOverflowPresenter exists as a class and has a default constructor basically to satisfy XAML infrastructure support, when it's specified as the TargetType of the Style used for a CommandBarOverflowPresenterStyle value.
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 Styling controls. 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 available locally with the SDK or NuGet package installation.
- WinUI Styles (recommended): For updated styles from WinUI, see
\Users\<username>\.nuget\packages\microsoft.ui.xaml\<version>\lib\uap10.0\Microsoft.UI.Xaml\Themes\generic.xaml. - Non-WinUI styles: For built-in styles, see
%ProgramFiles(x86)%\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\<SDK version>\Generic\generic.xaml.
Locations might be different if you customized the installation. Styles and resources from different versions of the SDK 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. Light-weight styling resources are available starting in Windows 10, version 1607 (SDK 14393).
