有时候需要动态的设置一些按钮的状态模板。使一个button显示不同的内容，比如Button未点击安装显示：
安装后显示：
可以通过设置button的content，通过content来设置不同的模板来实现功能，以下是代码：
MainWindow.xaml
<Windowx:Class="WPF_ButtonTemplate.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:local="clr-namespace:WPF_ButtonTemplate"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"Title="MainWindow"Width="800"Height="450"mc:Ignorable="d"><Window.Resources><BitmapImage x:Key="Setting_Extension" UriSource="pack://application:,,,/Installed.png" /><ControlTemplate x:Key="UnInstallTemplate" TargetType="Button"><Borderx:Name="border1"Width="100"Height="30"Background="LightGray"BorderBrush="DarkGray"BorderThickness="1.5"CornerRadius="8"><TextBlockx:Name="contentTB"HorizontalAlignment="Center"VerticalAlignment="Center"Text="{TemplateBinding Content}" /></Border></ControlTemplate><ControlTemplate x:Key="InstalledTemplate" TargetType="Button"><Border x:Name="border1" Background="LightYellow" CornerRadius="8"><StackPanel Margin="13,7,13,7" Orientation="Horizontal"><ImageWidth="16"Height="16"HorizontalAlignment="Left"VerticalAlignment="Center"Source="{DynamicResource Setting_Extension}" /><TextBlockx:Name="contentTB"Margin="4,0,0,0"HorizontalAlignment="Center"VerticalAlignment="Center"FontSize="{TemplateBinding FontSize}"Foreground="{TemplateBinding Foreground}"Text="{TemplateBinding Content}" /></StackPanel></Border></ControlTemplate><Style x:Key="NomalBtn" TargetType="Button"><Setter Property="Width" Value="100" /><Setter Property="Height" Value="30" /><Style.Triggers><Trigger Property="Content" Value="未安装"><Setter Property="Template" Value="{StaticResource UnInstallTemplate}" /></Trigger><Trigger Property="Content" Value="已安装"><Setter Property="Template" Value="{StaticResource InstalledTemplate}" /></Trigger></Style.Triggers></Style></Window.Resources><Grid><Buttonx:Name="btn"Click="Button_Click"Content="未安装"Style="{StaticResource NomalBtn}" /></Grid>
</Window>
