如何在Silverlight DataGrid中的编辑模式下更改单元格的文本颜色？

Question

In Silverlight 4 I have a DataGrid with a DataGridTextColumn . The cells in this column are editable. Now I have the problem that I changed the color of the whole grid to white on black instead of the default black on white. I managed to change all relevant colors, except for the text color of the cell during edit mode . This is still black, so it looks pretty bad.

Any hints how to do it? I've now spent plenty of time googling and searching for this problem but found no solution. Thanks in advance!

Try changing the background of the DataGridCell, the TextBox background in the DataGridTextColumn is transparent, so it should pickup the cell's background.

Here is something that worked for me:

<UserControl xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"  
         x:Class="DataGridTextBoxBackground.MainPage"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
         xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
         xmlns:p="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
         mc:Ignorable="d"
         d:DesignHeight="300" d:DesignWidth="400">

<Grid x:Name="LayoutRoot" Background="White">
    <Grid.Resources>
        <Style TargetType="p:DataGridCell">
            <Setter Property="Background" Value="Black" />
            <Setter Property="Foreground" Value="White" />
        </Style>
    </Grid.Resources>
    <sdk:DataGrid x:Name="gridItems" AutoGenerateColumns="False">
        <sdk:DataGrid.Columns>
            <sdk:DataGridTextColumn Binding="{Binding Name}" Header="Name" />
        </sdk:DataGrid.Columns>
    </sdk:DataGrid>
</Grid>

Here's the codebehind for the xaml above:

    namespace DataGridTextBoxBackground
{
    public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
            this.Loaded += new RoutedEventHandler(MainPage_Loaded);
        }

        void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            List<DataItem> items = new List<DataItem>();
            items.Add(new DataItem("item 1"));
            items.Add(new DataItem("item 2"));
            items.Add(new DataItem("item 3"));
            items.Add(new DataItem("item 4"));
            items.Add(new DataItem("item 5"));

            this.gridItems.ItemsSource = items;
        }
    }

    public class DataItem
    {
        public DataItem() { }

        public DataItem(string name)
        {
            Name = name;
        }
        public string Name { get; set; }
    }
}
