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!!!

csharp 复制代码
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
csharp 复制代码
// 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 DataGridRowStyle

使用多个 DataTrigger 为不同的状态设置不同的行背景颜色:

xml 复制代码
<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:

csharp 复制代码
// 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 DataRowViewRow 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。
