WPF引用外部样式

WPF引用外部样式

　假设一个应用程序中，某个窗口需要使用样式，但是样式非常多，写在一个窗口中代码分类不方便。最好Style写在专门的xaml文件中，然后引用到窗口中，就像HTML引用外部css文件一样。

　　实现方法：

　　1.创建新建项“添加/资源字典”Style.xaml，并添加Style样式

　　Code:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="BaseStyle" TargetType="{x:Type Control}">
        <Setter Property="Margin" Value="5" />
    </Style>
    <Style TargetType="{x:Type Button}" BasedOn="{StaticResource BaseStyle}">
        <Setter Property="Width" Value="80" />
        <Setter Property="Height" Value="27" />
    </Style>
    <Style TargetType="{x:Type GroupBox}" BasedOn="{StaticResource BaseStyle}">

    </Style>
    <Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource BaseStyle}">

    </Style>
    <Style TargetType="{x:Type CheckBox}" BasedOn="{StaticResource BaseStyle}">

    </Style>
    <Style TargetType="{x:Type ListBox}" BasedOn="{StaticResource BaseStyle}">

    </Style>
    <Style TargetType="{x:Type ProgressBar}" BasedOn="{StaticResource BaseStyle}">

    </Style>
    <Style TargetType="{x:Type TextBlock}" >
        <Setter Property="Margin" Value="5" />
    </Style>
</ResourceDictionary>

　　2.在窗口中引用外部资源，注意：在Window中添加外部样式需要指定key，而Application中则不需要，所以这里rdStyle就是引用外部样式Style.xaml的key

　　Code:

<Window x:Class="MSSQLDocCreator.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MSSQLDocCreator"
        Title="MainWindow" Height="602" Width="425" WindowStartupLocation="CenterScreen">
    <Window.Resources>
        <ResourceDictionary x:Key="rdStyle">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Style.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    ....
</Window>

　　3.将样式应用到窗口的布局上

　　Code:

<Window x:Class="MSSQLDocCreator.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MSSQLDocCreator"
        Title="MainWindow" Height="602" Width="425" WindowStartupLocation="CenterScreen">
    <Window.Resources>
    ...
    </Window.Resources>
    <Grid Resources="{StaticResource rdStyle}">
    ...
    </Grid>
</Window>

　　完整MainWindow.xaml

　　Code:

<Window x:Class="MSSQLDocCreator.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MSSQLDocCreator"
        Title="MainWindow" Height="602" Width="425"
WindowStartupLocation="CenterScreen">
    <Window.Resources>
        <ObjectDataProvider x:Key="bndOutputFeilds"
ObjectType="{x:Type local:AppHelper}" MethodName="GetDocFields" />
        <ResourceDictionary x:Key="rdStyle">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Style.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
    <Grid Resources="{StaticResource rdStyle}">

            <RowDefinition />
            <RowDefinition Height="Auto" />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <GroupBox Grid.Row="0" Header="MSSQL ConnectionString">
