Question

I have been working with WPF for some time.

I need to create the following control over Internet, but could not find appropriate.

Can anybody help how to implement this functionality. Value should be increasing or decreasing when clicked on control.
I found that I can use either Volume control or Slider, but not getting clear what I should use.

Thanks in anticipation.

Answer 1

I prefer to use a Progressbar for these kind of displays.
This is my implementation of a simple volume control looking pretty much like the one you show as an example:

public partial class MainWindow : Window, INotifyPropertyChanged
{

    private double _volume;
    private bool mouseCaptured = false;

    public double Volume
    {
        get { return _volume; }
        set
        {
            _volume = value;
            OnPropertyChanged("Volume");
        }
    }

    public MainWindow()
    {
        InitializeComponent();
        DataContext = this;
    }

    private void MouseMove(object sender, MouseEventArgs e)
    {
        if (Mouse.LeftButton == MouseButtonState.Pressed && mouseCaptured)
        {
            var x = e.GetPosition(volumeBar).X;
            var ratio = x/volumeBar.ActualWidth;
            Volume = ratio*volumeBar.Maximum;
        }
    }

    private void MouseDown(object sender, MouseButtonEventArgs e)
    {
        mouseCaptured = true;
        var x = e.GetPosition(volumeBar).X;
        var ratio = x / volumeBar.ActualWidth;
        Volume = ratio * volumeBar.Maximum;
    }

    private void MouseUp(object sender, MouseButtonEventArgs e)
    {
        mouseCaptured = false;
    }

    #region Property Changed

    public event PropertyChangedEventHandler PropertyChanged;

    private void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }

    #endregion


}

And the XAML:

<Window x:Class="VolumeControlApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="196" Width="319">
    <Window.Resources>
        <Style x:Key="VolumeStyle" TargetType="{x:Type ProgressBar}">
            <Setter Property="Foreground" Value="#FFB00606"/>
            <Setter Property="Background" Value="Transparent"/>
            <Setter Property="BorderBrush" Value="Transparent"/>
            <Setter Property="BorderThickness" Value="0"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ProgressBar}">
                        <Grid x:Name="TemplateRoot">
                            <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}"/>
                            <Rectangle x:Name="PART_Track"/>
                            <Grid x:Name="PART_Indicator" ClipToBounds="True" HorizontalAlignment="Left">
                                <Rectangle x:Name="Indicator" Fill="{TemplateBinding Foreground}" RadiusX="5" RadiusY="3"/>
                            </Grid>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <Grid Background="#FF363636">
        <Border Background="Gray" BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Center" VerticalAlignment="Center" CornerRadius="3" Padding="2">
            <Border Background="Black" CornerRadius="3">
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="Auto"/>
                        <ColumnDefinition/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Text="Vol:" Foreground="White" VerticalAlignment="Center" Margin="4 0"/>
                    <ProgressBar x:Name="volumeBar"  Height="10" 
                    Value="{Binding Volume}" 
                    Width="100"
                    MouseMove="MouseMove" 
                    MouseDown="MouseDown"
                    MouseUp="MouseUp" Style="{DynamicResource VolumeStyle}" Grid.Column="1"/>
                </Grid>
            </Border>
        </Border>
    </Grid>
</Window>
