【中文标题】Silverlight 如何将属性绑定到列表项值【英文标题】：Silverlight how to bind properties to List item values 【发布时间】：2017-08-22 23:31:05 【问题描述】：我是 XAML 的新手，正在使用这些功能。在这个阶段，我正在创建一个填充有静态数据的数据网格。
我想知道如何禁用某些行，我尝试将 IsEnabled 属性绑定到模型，然后为其赋予布尔值，如下所示：

C#
public MainPage()
InitializeComponent();
Data();
McDataGrid.ItemsSource = list;
public List<Model> list = new List<Model>();
private List<Model> Data()
list.Add(new Model(1, "Test", "1", true));
list.Add(new Model(2, "Ger", "2", true));
list.Add(new Model(3, "dsg", "3", true));
list.Add(new Model(4, "Hd", "4", false));
list.Add(new Model(5, "TeHRFdgst", "5", false));
return list;
public class Model : INotifyPropertyChanged
public int Id get; set;
public string Name get; set;
public string Prop get; set;
public bool enabled get; set;
public event PropertyChangedEventHandler PropertyChanged;
public Model(int id, string name, string prop, bool isenabled)
Id = id;
Name = name;
Prop = prop;
enabled = isenabled;
protected virtual void OnPropertyChanged(string propertyName)
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
但到目前为止，它只按预期为 IsEnabled 添加了一列，但我认为它也会设置属性值。
如果可能的话，有人能解释一下 XAML 和 C# 之间的绑定是如何工作的吗？
【问题讨论】：
Disable DataGridRows depending on a bool flag in WPF的可能重复 能否请您发布完整的 XAML 标记？ setter 是在哪里定义的，你到底想完成什么？ 我添加了完整的 XAML @mm8 【参考方案1】：您可以使用RowStyle 禁用一行：
<Style x:Key="DataGridStyle1" TargetType="sdk:DataGrid">
<Setter Property="RowStyle">
<Setter.Value>
<Style TargetType="sdk:DataGridRow">
<Setter Property="IsEnabled" Value="Binding enabled"/>
</Style>
</Setter.Value>
...
</Setter>

是的，效果很好，我知道你在那里做了什么，谢谢！以上是关于Silverlight 如何将属性绑定到列表项值的主要内容，如果未能解决你的问题，请参考以下文章
