将样式应用于网格视图

Question

我整个下午都在为此扯头发，希望有人可以帮助我。忍受我这个。

我的 App.xaml 中有许多样式可以转换网格视图，代码如下所示。

<Application.Resources>

    <Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}"
       TargetType="{x:Type ScrollViewer}">
        <Setter Property="Focusable"
            Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ScrollViewer}">
                    <Grid Background="{TemplateBinding Background}"
                      SnapsToDevicePixels="true">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="Auto"/>
                        </Grid.ColumnDefinitions>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="*"/>
                            <RowDefinition Height="Auto"/>
                        </Grid.RowDefinitions>
                        <DockPanel Margin="{TemplateBinding Padding}">

现在，这适用于我页面上的所有网格视图，我如何使这些样式适用于某些网格视图而不是其他网格视图？我已经尝试了一百万种不同的方法，但我确定我遗漏了一些明显的东西！请帮忙:-)

您必须将您的 Key 设为一个字符串，例如 <Style x:Key="myGridStyle" TargetType="{x:Type ScrollViewer}">，然后为您想要使用它的网格调用该样式。此外，如果您只设置 TargetType 而不是 Key，那么它将成为该 Type 的默认值，除非您覆盖它。
