WPF前端：一个纯Xaml的水平导航栏

效果图：

代码：

1、样式代码，可以写在窗体资源处或者样式资源文件中

 <Style x:Key="MenuRadioButtonStyle" TargetType="{x:Type RadioButton}"><Setter Property="FontSize" Value="16" /><Setter Property="Width" Value="100" /><Setter Property="Height" Value="40" /><!--<Setter Property="Foreground" Value="#333333" />--><Setter Property="Foreground"><Setter.Value><SolidColorBrush Color="#333333" /></Setter.Value></Setter><Setter Property="VerticalAlignment" Value="Center" /><Setter Property="Template"><Setter.Value><ControlTemplate TargetType="{x:Type RadioButton}"><Grid><Borderx:Name="bd"Margin="5,0,5,0"Background="#00FFFFFF"CornerRadius="20" /><ContentPresenterMargin="0,0,0,0"HorizontalAlignment="Center"VerticalAlignment="Center" /></Grid><ControlTemplate.Triggers><MultiTrigger><MultiTrigger.Conditions><Condition Property="IsMouseOver" Value="True" /><Condition Property="IsChecked" Value="False" /></MultiTrigger.Conditions><MultiTrigger.Setters><Setter TargetName="bd" Property="Background" Value="#AACCE8FF" /></MultiTrigger.Setters></MultiTrigger><Trigger Property="IsChecked" Value="True"><Trigger.EnterActions><BeginStoryboard><Storyboard><ColorAnimationStoryboard.TargetProperty="(RadioButton.Foreground).(SolidColorBrush.Color)"To="White"Duration="0:0:.2" /></Storyboard></BeginStoryboard></Trigger.EnterActions><Trigger.ExitActions><BeginStoryboard><Storyboard><ColorAnimationStoryboard.TargetProperty="(RadioButton.Foreground).(SolidColorBrush.Color)"To="#333333"Duration="0:0:.2" /></Storyboard></BeginStoryboard></Trigger.ExitActions></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style><Style x:Key="MenuSliderStyle" TargetType="Border"><Setter Property="Width" Value="100"/><Setter Property="Height" Value="40"/><Setter Property="Margin" Value="100,0,0,0"/><Setter Property="HorizontalAlignment" Value="Left"/><Setter Property="Background" Value="#14B9FF"/><Setter Property="CornerRadius" Value="20"/></Style>

2、在要使用的页面中

 <BorderWidth="500"Height="50"VerticalAlignment="Top"Background="#AAFFFFFF"CornerRadius="20"><Grid><Borderx:Name="menuBorder"Style="{StaticResource MenuSliderStyle}"><Border.RenderTransform><TranslateTransform x:Name="Move" X="0" /></Border.RenderTransform></Border><Grid HorizontalAlignment="Center"><Grid.ColumnDefinitions><ColumnDefinition /><ColumnDefinition /><ColumnDefinition /></Grid.ColumnDefinitions><RadioButtonx:Name="homeRB"Content="Home"IsChecked="True"Style="{StaticResource MenuRadioButtonStyle}"><RadioButton.Triggers><EventTrigger RoutedEvent="ToggleButton.Checked"><BeginStoryboard ><Storyboard><DoubleAnimationStoryboard.TargetName="menuBorder"Storyboard.TargetProperty="(UIElement.RenderTransform).(TranslateTransform.X)"To="0"Duration="0:0:.2" /></Storyboard></BeginStoryboard></EventTrigger></RadioButton.Triggers></RadioButton><RadioButtonx:Name="settingsRB"Grid.Column="1"Content="Settings"Style="{StaticResource MenuRadioButtonStyle}"><RadioButton.Triggers><EventTrigger RoutedEvent="ToggleButton.Checked"><BeginStoryboard><Storyboard><DoubleAnimationStoryboard.TargetName="menuBorder"Storyboard.TargetProperty="(UIElement.RenderTransform).(TranslateTransform.X)"To="100"Duration="0:0:.2" /></Storyboard></BeginStoryboard></EventTrigger></RadioButton.Triggers></RadioButton><RadioButtonx:Name="LogRB"Grid.Column="2"Content="Logs"Style="{StaticResource MenuRadioButtonStyle}"><RadioButton.Triggers><EventTrigger RoutedEvent="ToggleButton.Checked"><BeginStoryboard><Storyboard><DoubleAnimationStoryboard.TargetName="menuBorder"Storyboard.TargetProperty="(UIElement.RenderTransform).(TranslateTransform.X)"To="200"Duration="0:0:.2" /></Storyboard></BeginStoryboard></EventTrigger></RadioButton.Triggers></RadioButton></Grid></Grid></Border>

3、RadioButton就是每个功能按钮，配合Prism框架的导航功能使用，就可以在各个页面之间切换了。

如果需要增加按钮数量，需要进行如下操作：

1、在Grid.ColumnDefinitions中，有几个按钮就加到几列，这里是三个按钮，所以是三列。
