步骤条实现的效果：
步骤条控件是在listbox的基础上实现的。
一、
xaml代码:
<Window.Resources>
<convert1:StepListBarWidthConverter x:Key="StepListStepWidthConverter" />
<ControlTemplate x:Key="NormalItemTemplate" TargetType="ListBoxItem">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<ContentPresenter HorizontalAlignment="Center" Content="{TemplateBinding Content}" />
<Grid Grid.Row="1" Margin="2">
<Ellipse
Width="10"
Height="10"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Fill="#55DCF5" />
</Grid>
</Grid>
</ControlTemplate>
<Style x:Key="StepListBoxStyle" TargetType="ListBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBox">
<Grid>
<Rectangle
Width="510"
Height="4"
Margin="0,0,0,8"
HorizontalAlignment="Center"
VerticalAlignment="Bottom"
Fill="#55DCF5" />
<ItemsPresenter />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<ControlTemplate x:Key="SelectedTemplate" TargetType="ListBoxItem">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<ContentPresenter HorizontalAlignment="Center" Content="{TemplateBinding Content}" />
<Grid Grid.Row="1" Margin="2">
<Ellipse
Width="8"
Height="8"
VerticalAlignment="Center"
Panel.ZIndex="3">
<Ellipse.Fill>
<SolidColorBrush Color="#FFFFFF" />
</Ellipse.Fill>
</Ellipse>
<Ellipse
Width="12"
Height="12"
VerticalAlignment="Center"
Panel.ZIndex="2">
<Ellipse.Fill>
<SolidColorBrush Color="#225BA7" />
</Ellipse.Fill>
</Ellipse>
<Ellipse
Width="16"
Height="16"
VerticalAlignment="Center"
Panel.ZIndex="1">
<Ellipse.Fill>
<SolidColorBrush Color="#FFFFFF" />
</Ellipse.Fill>
</Ellipse>
</Grid>
</Grid>
</ControlTemplate>
<Style x:Key="ListBoxItemStyle" TargetType="ListBoxItem">
<Setter Property="Width" Value="{Binding RelativeSource={RelativeSource AncestorType=ListBox}, Converter={StaticResource StepListStepWidthConverter}}" />
<Setter Property="FontSize" Value="16" />
<Setter Property="FontFamily" Value="SimHei" />
<Setter Property="Foreground" Value="#ACF1FE" />
<Setter Property="Template" Value="{StaticResource NormalItemTemplate}" />
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Trigger.Setters>
<Setter Property="Template" Value="{StaticResource SelectedTemplate}" />
<Setter Property="FontSize" Value="20" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontFamily" Value="SimHei" />
</Trigger.Setters>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<StackPanel Background="SteelBlue">
<ListBox
Margin="0 200 0 0"
x:Name="NavList"
HorizontalAlignment="Center"
BorderThickness="0"
Foreground="#225BA7"
IsEnabled="False"
ItemContainerStyle="{StaticResource ListBoxItemStyle}"
SelectedIndex="4"
Style="{StaticResource StepListBoxStyle}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel IsItemsHost="False" Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBoxItem>1</ListBoxItem>
<ListBoxItem>2</ListBoxItem>
<ListBoxItem>3</ListBoxItem>
<ListBoxItem>4</ListBoxItem>
<ListBoxItem>5</ListBoxItem>
<ListBoxItem>6</ListBoxItem>
</ListBox>
<StackPanel HorizontalAlignment="Center" Orientation="Horizontal">
<Button Click="Button_Click">下一步</Button>
<Button Margin="100,0,0,0" Click="Button_Click_1">首页</Button>
</StackPanel>
</StackPanel>
各个样式模板介绍：StepListBoxStyle，整个步骤条控件的样式，矩形长条模板。
NormalItemTemplate，未被选中时单个步骤样式。
SelectedTemplate，被选中时单个步骤样式。
ListBoxItemStyle，通过样式和触发器使用模板。
二、需要固定步骤条总长度，根据项数设置步骤条步长，所以需要写个转换器，设置每项长度。
转换器代码：
class StepListBarWidthConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
ListBox listBox = value as ListBox;
if (listBox==null)
{
return Binding.DoNothing;
}
if (listBox.Items.Count == 0)
{
return 0;
}
return 510 / (listBox.Items.Count - 1);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return Binding.DoNothing;
}
}
使用的时候对Listbox的ItemSource和SelectedIndex进行绑定即可。
