您可以处理 DataGrid 的 LoadingRow 事件来检测何时添加行。在事件处理程序中，您可以获得对添加到充当 ItemsSource 的 DataTable 的 DataRow 的引用。然后您可以根据需要更新 DataGridRow 的颜色。

void dataGrid_LoadingRow(object sender, Microsoft.Windows.Controls.DataGridRowEventArgs e)
{
    // Get the DataRow corresponding to the DataGridRow that is loading.
    DataRowView item = e.Row.Item as DataRowView;
    if (item != null)
    {
        DataRow row = item.Row;

            // Access cell values values if needed...
            // var colValue = row["ColumnName1]";
            // var colValue2 = row["ColumName2]";

        // Set the background color of the DataGrid row based on whatever data you like from 
        // the row.
        e.Row.Background = new SolidColorBrush(Colors.BlanchedAlmond);
    }           
}

要在 XAML 中注册活动：

<toolkit:DataGrid x:Name="dataGrid"
    ...
    LoadingRow="dataGrid_LoadingRow">

或在 C# 中：

this.dataGrid.LoadingRow += new EventHandler<Microsoft.Windows.Controls.DataGridRowEventArgs>(dataGrid_LoadingRow);

You can handle the DataGrid's LoadingRow event to detect when a row is being added. In the event handler you can get a reference to the DataRow that was added to the DataTable that is acting as your ItemsSource. Then you can update the DataGridRow's color however you like.

void dataGrid_LoadingRow(object sender, Microsoft.Windows.Controls.DataGridRowEventArgs e)
{
    // Get the DataRow corresponding to the DataGridRow that is loading.
    DataRowView item = e.Row.Item as DataRowView;
    if (item != null)
    {
        DataRow row = item.Row;

            // Access cell values values if needed...
            // var colValue = row["ColumnName1]";
            // var colValue2 = row["ColumName2]";

        // Set the background color of the DataGrid row based on whatever data you like from 
        // the row.
        e.Row.Background = new SolidColorBrush(Colors.BlanchedAlmond);
    }           
}

To sign up for the event in XAML:

<toolkit:DataGrid x:Name="dataGrid"
    ...
    LoadingRow="dataGrid_LoadingRow">

Or in C#:

this.dataGrid.LoadingRow += new EventHandler<Microsoft.Windows.Controls.DataGridRowEventArgs>(dataGrid_LoadingRow);

尝试这个

在XAML中

<Window.Resources>
<Style TargetType="{x:Type DataGridRow}">
    <Style.Setters>
        <Setter Property="Background" Value="{Binding Path=StatusColor}"></Setter>
    </Style.Setters>            
</Style>
</Window.Resources>

在数据网格中

<DataGrid AutoGenerateColumns="False" CanUserAddRows="False" Name="dtgTestColor" ItemsSource="{Binding}" >
<DataGrid.Columns>                            
    <DataGridTextColumn Header="Valor" Binding="{Binding Path=Valor}"/>
</DataGrid.Columns>
</DataGrid>

在代码中我有一个类

public class ColorRenglon
{
    public string Valor { get; set; }
    public string StatusColor { get; set; }
}

当设置DataContext时

dtgTestColor.DataContext = ColorRenglon;
dtgTestColor.Items.Refresh();

如果您没有设置行的颜色默认值为灰色

尝试这个示例
与这个样本

List<ColorRenglon> test = new List<ColorRenglon>();
ColorRenglon cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va un color"; 
cambiandoColor.StatusColor = "Red";
test.Add(cambiandoColor);
cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va otro color"; 
cambiandoColor.StatusColor = "PaleGreen";
test.Add(cambiandoColor);

Try this

In the XAML

<Window.Resources>
<Style TargetType="{x:Type DataGridRow}">
    <Style.Setters>
        <Setter Property="Background" Value="{Binding Path=StatusColor}"></Setter>
    </Style.Setters>            
</Style>
</Window.Resources>

In the datagrid

<DataGrid AutoGenerateColumns="False" CanUserAddRows="False" Name="dtgTestColor" ItemsSource="{Binding}" >
<DataGrid.Columns>                            
    <DataGridTextColumn Header="Valor" Binding="{Binding Path=Valor}"/>
</DataGrid.Columns>
</DataGrid>

In the code i have a class with

public class ColorRenglon
{
    public string Valor { get; set; }
    public string StatusColor { get; set; }
}

When set the DataContext

dtgTestColor.DataContext = ColorRenglon;
dtgTestColor.Items.Refresh();

If you have not set the color of the row the default value is Grey

Try this sample
with this sample

List<ColorRenglon> test = new List<ColorRenglon>();
ColorRenglon cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va un color"; 
cambiandoColor.StatusColor = "Red";
test.Add(cambiandoColor);
cambiandoColor = new ColorRenglon();
cambiandoColor.Valor = "Aqui va otro color"; 
cambiandoColor.StatusColor = "PaleGreen";
test.Add(cambiandoColor);
