一、前言

在XAML中使用自定义控件，并在XAML中并赋初始值。

二、使用步骤

1. cs中设置控件属性

设置OriginLocation，ScaleInterval 属性，可以通过XAML内传初始值

using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Shapes;public partial class RadarChart : UserControl
{//原点位置private static readonly DependencyProperty OriginLocationProperty =DependencyProperty.Register("OriginLocation", typeof(string), typeof(RadarChart));//刻度间隔private static readonly DependencyProperty ScaleIntervalProperty =DependencyProperty.Register("ScaleInterval",typeof(int),typeof(RadarChart));public string OriginLocation {get { return (string)GetValue(OriginLocationProperty); }set { SetValue(OriginLocationProperty, value); }}public int ScaleInterval {get { return (int)GetValue(ScaleIntervalProperty); }set { SetValue(ScaleIntervalProperty, value); }}}   

2. 在引入控件时，Xaml传初始值

<components:RadarChart OriginLocation="upleft" ScaleInterval="10" />
