        <Style TargetType="{x:Type TabControl}">
            <Setter Property="Margin" Value="0,5" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type TabControl}">
                        <Grid>

                                <RowDefinition Height="Auto" />
                                <RowDefinition Height="*" />
                            </Grid.RowDefinitions>
                            <Grid Grid.Row="0">
                                <Button Style="{StaticResource Button}"/>
                                <Button />
                            </Grid>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

        <Style TargetType="{x:Type TabItem}">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="TabItem">
                        <Grid Name="xGrid">
                            <Border>
                                <ContentPresenter/>
                            </Border>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

        <Style x:Key="Button" TargetType="{x:Type Button}">
            <Setter Property="Background" Value="#FF000000" />
        </Style>
</ResourceDictionary>

我试图为按钮添加样式，但如果我在项目中添加它（<Button Grid.Column="0" Style="{StaticResource Button}"/>），我的项目就不会运行，并且VS不会显示我是一个例外。

我的样式保存在单独的文件中。

为什么我不能为按钮添加样式？ VS没有告诉我什么例外？

我会接受任何帮助。

感谢。

P.S。对不起，如果有的话。

Answer 1

您是否已将ResourceDictionary合并到App.xaml？

<Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:WpfApplication1"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionary1.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

将Dictionary1.xaml替换为ResourceDictionary文件的实际名称。

Answer 2

“Button”的最后一种风格需要在“TabControl”风格之前移动。
