C# 在修改wpf中任何矩形的高度后，如何重新排列画布上的矩形？,c#,wpf,canvas,drawrectangle,C#,Wpf,Canvas,Drawrectangle,我正在从用户直接在网格行中输入的网格单元格值添加矩形。当我修改特定列的值时，比如说Thickness，即Height，然后它会增加所选行矩形的Height，但它不会将其下方的所有矩形完全重新排列在所选行矩形之后 在xaml.cs中 public class MyLayer : INotifyPropertyChanged { public string Thickness { get; set; } public string OffsetRight { get; set;

将
项
声明为代码中的
公共可观测集合项{get；set；}

现在，您的
Add（）
函数可以是：

private void Add() {
  var rect = new Rectangle {
    Stroke = Brushes.Red,
    StrokeThickness = 1,
    Height = Convert.ToDouble(txtheight.Text),
    Width = 100
  };
  Items.Add(rect);
}
至于在编辑现有控件时的更新，在这种情况下将是自动的。没有硬编码的定位，因为布局容器为您处理所有这些混乱

当然，您可以将
项
集合类型切换到您自己的自定义控件类型
MyLayer
，并且通过它实现INPC，更改仍然是自动的。您现在必须定义一个
DataTemplate
，以获得要呈现的项目，但这就像在xaml中完成3行工作一样

当需要调整现有控件时，也可以直接使用
Items
属性，而不必在代码隐藏中引用
ItemsControl
。绑定应该自动处理视图的更新。

即使是用<代码>画布>代码>，也可以做到。但是，你应该考虑使用一个类似于<代码> ITEMsScript < /代码>的东西。

将
项
声明为代码中的
公共可观测集合项{get；set；}

现在，您的
Add（）
函数可以是：

private void Add() {
  var rect = new Rectangle {
    Stroke = Brushes.Red,
    StrokeThickness = 1,
    Height = Convert.ToDouble(txtheight.Text),
    Width = 100
  };
  Items.Add(rect);
}
至于在编辑现有控件时的更新，在这种情况下将是自动的。没有硬编码的定位，因为布局容器为您处理所有这些混乱

当然，您可以将
项
集合类型切换到您自己的自定义控件类型
MyLayer
，并且通过它实现INPC，更改仍然是自动的。您现在必须定义一个
DataTemplate
，以获得要呈现的项目，但这就像在xaml中完成3行工作一样

当需要调整现有控件时，也可以直接使用
Items
属性，而不必在代码隐藏中引用
ItemsControl
。绑定应自动处理视图的更新。
