silverlight - 图像中的 Silverlight 边框

Question

我想做一个通用控件，它会有漂亮的边框和内部内容呈现器（这将是：左上角左上边框）

这是我选择的一种方式，因为没有平铺的图像画笔。我已经预定义了图块（10 个对于我的应用程序中的所有场景都足够了）。它可以工作，但是我必须明确指定此边框控件的宽度/高度，因为预定义的图块正在扩大网格。有没有办法让它根据内容的宽度/高度自动调整大小，或者一些不同的更优雅的方式？

using System.Windows.Markup;
using Barbar.SilverFramework.Controls;
[ContentProperty("UserContent")]
public partial class Border : UserControlEx {
  public Border() {
    InitializeComponent();
  }

  public object UserContent {
    get { return contentPresenter.Content; }
    set { contentPresenter.Content = value; }
  }
}

编辑： 我最终得到了这个解决方案（创建自己的“隐藏”结果大小的 StackPanel），由于在内容控件中引用了 x:Name="" 项，我也从 UserControl 移动到了 ContentControl；如果有人知道更优雅的方式，我想知道：

using System;
using System.Windows;
using System.Windows.Controls;
namespace Barbar.SilverFramework.Controls {
  public class NoSizeStackPanel : Panel {
    public static readonly DependencyProperty OrientationProperty =
              DependencyProperty.Register(
            "Orientation",
            typeof(Orientation),
            typeof(NoSizeStackPanel),
            new PropertyMetadata(Orientation.Horizontal, null));

    public Orientation Orientation {
      get {
        return (Orientation)base.GetValue(NoSizeStackPanel.OrientationProperty);
      }
      set {
        base.SetValue(NoSizeStackPanel.OrientationProperty, value);
      }
    }


    protected override Size MeasureOverride(Size availableSize) {
      var children = Children;
      for (int i = 0; i < children.Count; i++) {
        children[i].Measure(availableSize);
      }
      return new Size(0, 0);
    }

    protected override Size ArrangeOverride(Size finalSize) {
      // Get the collection of children
      var children = Children;
      double w = 0;
      double h = 0;
      double mh = 0;
      double mw = 0;
      for (int i = 0; i < children.Count; i++) {
        var point = (Orientation == Orientation.Horizontal) ?
           new Point(w, 0) : new Point(0, h);

        double dw = children[i].DesiredSize.Width;
        double dh = children[i].DesiredSize.Height;

        mh = Math.Max(mh, dh);
        mw = Math.Max(mw, dw);

        w += dw;
        h += dh;

        children[i].Arrange(new Rect(point.X, point.Y, dw, dh));
      }

      return (Orientation == Orientation.Horizontal) ?
        new Size(w, mh) : new Size(mw, h);
    }
  }
}

using System.Windows.Controls;
namespace Barbar.D20.SilverClient.Views.Controls.UI {
  public class Border : ContentControl {
    public Border() {
      this.DefaultStyleKey = typeof(Border);
    }
  }
}
