RichTextBox滚动条图像作为背景C＃WPF

Question

I want to have image as background in my richtextbox command. I'm using, but I can only set background value to already defined colors, not images. (I were using scrollbarviewer but it doesnt show in my richtextbox)

<RichTextBox x:Name="richTextBox" HorizontalAlignment="Left" Height="285" VerticalAlignment="Top" Width="880" VerticalScrollBarVisibility="Visible" IsReadOnly="True" Foreground="#FFA02626" Background="{x:Null}">
            <RichTextBox.Resources>
                <Style TargetType="ScrollBar">
                    <Setter Property="Background" Value="Red"/>
                </Style>
            </RichTextBox.Resources>
</RichTextBox>

Answer 1

The Value can be any object, so it can be an ImageBrush. You can do it with the element syntax.

<RichTextBox x:Name="richTextBox" HorizontalAlignment="Left" Height="285" VerticalAlignment="Top" Width="880" VerticalScrollBarVisibility="Visible" IsReadOnly="True" Foreground="#FFA02626" Background="{x:Null}">
    <RichTextBox.Resources>
        <Style TargetType="ScrollBar">
            <Setter Property="Background">
                <Setter.Value>
                <ImageBrush ImageSource="cool-northern-lights-pic-4.jpg"/>
                </Setter.Value>
            </Setter>
        </Style>
    </RichTextBox.Resources>
</RichTextBox>

Try like this-

<RichTextBox>
    <RichTextBox.Background>
        <ImageBrush ImageSource="some.jpg"/>
    </RichTextBox.Background>
</RichTextBox>

See if this helps.
