还是不习惯数据绑定的方式，总是想用getcontrol先获取控件，再对控件进行处理。我注释后，绑定也很方便！！！

private void Window_Loaded(object sender, RoutedEventArgs e)
{DataTable dataTable = new DataTable();dataTable.Columns.Add("序号", typeof(int));dataTable.Columns.Add("测试项", typeof(string));dataTable.Columns.Add("状态", typeof(string));dataTable.Columns.Add("值", typeof(string));for (int j = 1; j <= 40; j++){dataTable.Rows.Add(j, "读SN", j < 10?"PASS":"FAIL","FT123456789");}for (int i = 0; i < bindingList.Count; i++){//TextBlock myCom = (TextBlock)MyAPI.getControl(myListBox, i, "myCom");//DataGrid myDataGrid = (DataGrid)MyAPI.getControl(myListBox, i, "myDataGrid");//if (myDataGrid != null)//{//    myDataGrid.ItemsSource = dataTable.DefaultView;//}bindingList[i].DataGridCollection = dataTable.DefaultView;//TextBlock myStatus = (TextBlock)MyAPI.getControl(myListBox, i, "myStatus");//myStatus.Text = "PASS";bool b = true;for (int k = 0; k < dataTable.Rows.Count; k++) {if (dataTable.Rows[k]["状态"].Equals("FAIL")){b = false;}}bindingList[i].Status = b?"PASS":"FAIL";//TextBlock myLog = (TextBlock)MyAPI.getControl(myListBox, i, "myLog");//myLog.Text = "测试完成";bindingList[i].Log = "测试完成";}
}

触发示例：多种状态对应不同颜色

DataTrigger 可以设置多种状态，每种状态对应不同的颜色。你可以为 DataGridRow 设置多个 DataTrigger，根据不同的条件更改行的颜色。假设你有一个 Status 列，不同的状态对应不同的颜色，比如 “Green”、“Yellow”、“Red” 等。

示例：多种状态对应不同颜色

假设 DataTable 中有一个 Status 列，根据 Status 的值来设置不同的背景颜色。

1. 创建 DataTable 并绑定到 DataGrid

// 创建 DataTable
DataTable table = new DataTable();
table.Columns.Add("Name", typeof(string));
table.Columns.Add("Status", typeof(string)); // 状态列，用于改变颜色// 添加示例数据
table.Rows.Add("Item 1", "Green");  // 对应绿色
table.Rows.Add("Item 2", "Yellow"); // 对应黄色
table.Rows.Add("Item 3", "Red");    // 对应红色// 绑定到 DataGrid
myDataGrid.ItemsSource = table.DefaultView;

2. 在 XAML 中定义 DataGrid 的 RowStyle

使用多个 DataTrigger 为不同的状态设置不同的行背景颜色：

<DataGrid x:Name="myDataGrid" AutoGenerateColumns="True"><DataGrid.RowStyle><Style TargetType="DataGridRow"><Setter Property="Background" Value="White" /> <!-- 默认背景色 --><Style.Triggers><!-- 当 Status 为 "Green" 时，将行背景设置为绿色 --><DataTrigger Binding="{Binding Path=Row[Status]}" Value="Green"><Setter Property="Background" Value="LightGreen" /></DataTrigger><!-- 当 Status 为 "Yellow" 时，将行背景设置为黄色 --><DataTrigger Binding="{Binding Path=Row[Status]}" Value="Yellow"><Setter Property="Background" Value="Yellow" /></DataTrigger><!-- 当 Status 为 "Red" 时，将行背景设置为红色 --><DataTrigger Binding="{Binding Path=Row[Status]}" Value="Red"><Setter Property="Background" Value="Salmon" /></DataTrigger><!-- 你可以添加更多状态和对应的颜色 --></Style.Triggers></Style></DataGrid.RowStyle>
</DataGrid>

3. 动态修改 DataTable 行状态

你可以在代码中动态修改 Status 列的值来触发颜色变化：

// 将第一行的状态设置为 "Red"，触发行背景变为红色
table.Rows[0]["Status"] = "Red";

解释

• Path=Row[Status]：绑定到 DataRowView 的 Row 属性中的 Status 列。
• 每个 DataTrigger 针对 Status 列的不同值设置不同的背景颜色。
• 你可以根据需要添加更多的 DataTrigger，为更多的状态设置不同的颜色。

这样，你可以通过修改 DataTable 中的状态值，动态控制 DataGrid 中行的颜色变化。
