WPF实现轮播图

1、效果图

 

2、前端代码

<Window x:Class="LiveChartDemo.View.CarouselView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:LiveChartDemo.View"
mc:Ignorable="d" Background="Transparent"
Title="CarouselView" Height="380" Width="800">
<Grid Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<StackPanel>
<Image x:Name="CarouselViewImg1" Source="../Img\01.jpg" Stretch="UniformToFill"/>
<!--<Image x:Name="CarouselViewImg1" Source="{Binding ImgUrl}" Stretch="UniformToFill"/>-->
</StackPanel>
<StackPanel Margin="0 310 0 0" Panel.ZIndex="999">
<UniformGrid Columns="5" Background="Transparent" VerticalAlignment="Center" HorizontalAlignment="Center">
<Border Width="15" Height="15" Background="#4FD761" Margin="5" Name="TipButton1" MouseDown="ClickButton" Tag="1"/>
<Border Width="15" Height="15" Background="#F0AF53" Name="TipButton2" MouseDown="ClickButton" Tag="2"/>
<Border Width="15" Height="15" Background="#F0AF53" Name="TipButton3" MouseDown="ClickButton" Tag="3"/>
<Border Width="15" Height="15" Background="#F0AF53" Name="TipButton4" MouseDown="ClickButton" Tag="4"/>
<Border Width="15" Height="15" Background="#F0AF53" Name="TipButton5" MouseDown="ClickButton" Tag="5"/>
</UniformGrid>
</StackPanel>
</Grid>
</Window>
