WPF 自定义进度条

WPF设计界面过程中，有时需要设计一种可以手动滑动修改并实时显示的进度条

进度条，效果如下：

颜色、图标、节点什么的，都可以重新替换。

前端XAML代码：

<UserControl x:Class="WpfApplication2.ProgressBarControl"

    /// </summary>
    public partial class ProgressBarControl : UserControl
    {
        public ProgressBarControl()
        {
            InitializeComponent();
        }

        private void ProgressBarControl_OnLoaded(object sender, RoutedEventArgs e)
        {
            MySlider.Value = Value;
        }
        #region 属性
        /// <summary>
        /// 进度条值
        /// </summary>
        public double Value
        {
            get { return (double)GetValue(ValueProperty); }
            set
            {
                SetValue(ValueProperty, value);
            }
        }

        public static readonly DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(double)
        , typeof(ProgressBarControl), new PropertyMetadata(1.0));

        #endregion

    }

2、界面引用

<wpfApplication2:ProgressBarControl Width="300" Value="2" VerticalAlignment="Center"></wpfApplication4:ProgressBarControl>
