WPF Frame 简单页面切换示例

原理比较简单，但是有个坑，为了使界面能够正确更新，记得使用 INotifyPropertyChanged 接口来实现属性更改通知。

<Window x:Class="PageTest.MainWindow"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:PageTest"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><Grid.RowDefinitions><RowDefinition Height="0.1*"/><RowDefinition/></Grid.RowDefinitions><StackPanel Orientation="Horizontal"><Button Width="50" Height="25" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="5" Click="Button_Click"></Button><Button Width="50" Height="25" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="5" Click="Button_Click_1"></Button></StackPanel><Frame Grid.Row="1" Content="{Binding CurMain}" NavigationUIVisibility="Hidden"></Frame></Grid>
</Window>
