WPF 实战 - 翻页控件

1. 先上效果

<StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
    <StackPanel Margin="50 0">
        <local:PaginationControl IsDisplayFirstLastPageButton="False" PageStyle="TextLeft"/>
        <local:PaginationControl IsDisplayFirstLastPageButton="False" PageStyle="TextCenter"/>
        <local:PaginationControl IsDisplayFirstLastPageButton="False" PageStyle="TextRight"/>
    </StackPanel>
    <StackPanel>
        <local:PaginationControl IsDisplayFirstLastPageButton="True" PageStyle="TextLeft"/>
        <local:PaginationControl IsDisplayFirstLastPageButton="True" PageStyle="TextCenter"/>
        <local:PaginationControl IsDisplayFirstLastPageButton="True" PageStyle="TextRight"/>
    </StackPanel>
</StackPanel>

2. 封装的代码

<UserControl x:Class="WpfApp1.PaginationControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:WpfApp1"
             mc:Ignorable="d" x:Name="uctrl_PageControl">
