如何在WPF中定义窗体模板

可以在app.xaml中定义一个ControlTemplate，指定TargetType为Window

<Application x:Class="WpfApplication1.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="Window1.xaml">
    <Application.Resources>
 <ControlTemplate x:Key="WindowControlTemplate1" TargetType="{x:Type Window}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" > <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="0.93*"/> <RowDefinition Height="Auto"/>  Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.21*"/> <ColumnDefinition Width="0.79*"/>  Grid.ColumnDefinitions> <ContentPresenter Grid.ColumnSpan="2" Grid.Row="1" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" /> <ResizeGrip HorizontalAlignment="Right" x:Name="WindowResizeGrip" VerticalAlignment="Bottom" IsTabStop="False" Visibility="Collapsed" Grid.Column="1" Grid.Row="2" /> <TextBlock Text="My Logo" /> <TextBlock Grid.Column="1" Text="My Title"/> <StatusBar Height="20" Grid.ColumnSpan="2" Grid.Row="2"/>  Grid>  Border> <ControlTemplate.Triggers> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="ResizeMode" Value="CanResizeWithGrip"/> <Condition Property="WindowState" Value="Normal"/>  MultiTrigger.Conditions> <Setter Property="Visibility" TargetName="WindowResizeGrip" Value="Visible"/>  MultiTrigger>  ControlTemplate.Triggers>  ControlTemplate>     
   Application.Resources>
 Application> 

然后在窗体中可以像下面这样使用

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300" Template="{DynamicResource WindowControlTemplate1}">
    
    <Button Grid.Row="1" Grid.Column="1" Content="Hello,World">
   Button>
    
 Window>
