|ZYCWPF| 为什么自定义控件后，在XAML中写的属性无效呢？而且加了滚动条，但没有出现？谢谢
这是我的ZRichTextBox的自定义样式

    <Style TargetType="{x:Type control:ZRichTextBox}">

        <Setter Property="Template">

            <Setter.Value>

                <ControlTemplate TargetType="{x:Type control:ZRichTextBox}">

                    <DockPanel LastChildFill="True">

                        <Border DockPanel.Dock="Top" SnapsToDevicePixels="True"

                            BorderBrush="{TemplateBinding ToolbarBorderBrush}"

                            BorderThickness ="{TemplateBinding ToolbarBorderThickness}">

                            <StackPanel Height="24" Orientation="Horizontal"

                                Background="{TemplateBinding ToolbarBackground}">

                            .....这里为我的工具栏按钮

                            </StackPanel>

                        </Border>

                        <ScrollViewer x:Name="PART_ContentHost" VerticalScrollBarVisibility="Auto"  HorizontalScrollBarVisibility="Auto">

                        </ScrollViewer>

                    </DockPanel>

                </ControlTemplate>

            </Setter.Value>

        </Setter>

    </Style>

然后我XAML中用
<zc:ZRichTextBox x:Name="richTextBox" Background="#FFD2CB84" >
发现问题
1：Background="#FFD2CB84" 对RichTextBox不起效果
2：RIchTextBox内容多的时候还是不会出现滚动条

谢谢

1。 ScrollViewer改成：

    <ScrollViewer x:Name="PART_ContentHost" VerticalScrollBarVisibility="Auto"  HorizontalScrollBarVisibility="Auto"
