Costom ScrollViewer Wpf

I have made a slider that looks like the image below but I want to know if it’s possible to make the exact same thing but vertical and a ScrollViewer instead of a slider. I have tried a lot but not succeeded. Need it for a Listbox. I like that design a lot

Can u send me you'r part from .xaml code? One moment, i will post code in 5 min Done - First, you need to create a Grid with two columns: one for the ScrollViewer containing the ListBox, and one to display the Slider. - The horizontal ScrollBar should be disabled since we don’t need it, and the vertical ScrollBar should be hidden. - You'll set it so that when the MainWindow is loaded, the Slider's maximum value is set to match the scrollable height of the ScrollViewer. Here is my xaml code for u

    <Grid>
        <Grid.ColumnDefinitions>
            <!-- Here will be ListBox with ScrollViewer-->
            <ColumnDefinition Width="300"/>  // 0
            <!-- Here will be Slider Vertical -->
            <ColumnDefinition Width="20"/> // 1
            <!-- Used just for another Content-->
            <ColumnDefinition Width="*"/>  // 2
        </Grid.ColumnDefinitions>

        <Grid Grid.Column="1">
            <Slider x:Name="VerticalSlider" Minimum="0" Maximum="1" Orientation="Vertical"
                    HorizontalAlignment="Center" Margin="0,20,0,20" ValueChanged="VerticalSlider_ValueChanged"/>
        </Grid>

        <Grid Grid.Column="0">
            <ScrollViewer x:Name="scrollViewer" VerticalScrollBarVisibility="Hidden"
                      HorizontalScrollBarVisibility="Disabled">
                <ListBox x:Name="listBox" ScrollViewer.VerticalScrollBarVisibility="Hidden">
                    <!-- Elementele din ListBox -->
                    <ListBoxItem Content="Item 1" Height="60" />
                    <ListBoxItem Content="Item 2" Height="60" />
                    <ListBoxItem Content="Item 3" Height="60" />
                    <ListBoxItem Content="Item 4" Height="60" />
                    <ListBoxItem Content="Item 5" Height="60" />
                    <ListBoxItem Content="Item 6" Height="60" />
                    <ListBoxItem Content="Item 7" Height="60" />
                    <ListBoxItem Content="Item 8" Height="60" />
                    <ListBoxItem Content="Item 9" Height="60" />

In the backend code (xaml.cs), make sure to have the following: - At the top of MainWindow, add the Loaded event to set the slider’s maximum value based on the scrollable content.

<Window x:Class="Echofy_Music_Player.View.Test"
       //YOU'R CONTENT WITH
        Loaded="Window_Loaded">

<Window x:Class="Echofy_Music_Player.View.Test"
       //YOU'R CONTENT WITH
        Loaded="Window_Loaded">

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            // Setăm valoarea maximă a slider-ului în funcție de conținutul care poate fi derulat
            VerticalSlider.Maximum = scrollViewer.ScrollableHeight;
        }

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            // Setăm valoarea maximă a slider-ului în funcție de conținutul care poate fi derulat
            VerticalSlider.Maximum = scrollViewer.ScrollableHeight;
        }

- Also, include an event called VerticalSlider_ValueChanged to sync the slider’s current position with the scrolling position.

private void VerticalSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
        {
            scrollViewer.ScrollToVerticalOffset(e.NewValue);
        }

private void VerticalSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
        {
            scrollViewer.ScrollToVerticalOffset(e.NewValue);
        }
