C# Datagrid行前景色更改不起作用

这是以下内容的延续：

因此，我通过以下方式构建数据网格：

string[] columnLabels = new string[] { "Column 0", "Column 1", "Column 2", "Column 3", "Column 4", "Column 5" };

foreach (string label in columnLabels)
{
  DataGridTextColumn column = new DataGridTextColumn();
  column.Header = label;
  column.Binding = new Binding(label.Replace(' ', '_'));

  dtgResults.Columns.Add(column);
}

int[] ivalues = new int[] { 0, 1, 2, 3 };
string[] svalues = new string[] { "A", "B", "C", "D" };

dynamic row = new ExpandoObject();

for (int i = 0; i < 6; i++)
{

  switch (i)
  {
   case 0:
   case 1:
   case 2:
    string str = columnLabels[i].Replace(' ', '_');
    ((IDictionary<String, Object>)row)[str] = ivalues[i];
    break;

   case 3:
   case 4:
   case 5:
    string str2 = columnLabels[i].Replace(' ', '_');
    ((IDictionary<String, Object>)row)[str2] = svalues[i - 3];
  break;

  }
}
dtgResults.Items.Add(row);

但这不会改变你的想法，把它添加到你的xaml中

<DataGrid Name="dtg" Background="Transparent">
  <DataGrid.Resources>
    <Style TargetType="DataGridCell">
       <EventSetter Event="DataGridCell.Loaded" Handler="DataGridCell_Load"/>
          <Setter Property="Tag" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}}"/>
            <Setter Property="HorizontalAlignment" Value="Right" />
              </Style>
  </DataGrid.Resources>

它为我改变了文本的颜色。好的，通过这样做，我也得到了单元格内容和行，但是列呢？反过来说：通过int column=cell.column.DisplayIndex得到列；按int行的行=-1；DataGridRow rowContainer=parentDataGrid.GetRow（0）；对于（int iii=0；iii<DataGrid Name="dtg" Background="Transparent"> <DataGrid.Resources> <Style TargetType="DataGridCell"> <EventSetter Event="DataGridCell.Loaded" Handler="DataGridCell_Load"/> <Setter Property="Tag" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGrid}}"/> <Setter Property="HorizontalAlignment" Value="Right" /> </Style> </DataGrid.Resources>

private void DataGridCell_Load(object sender, RoutedEventArgs e)
{
  DataGridCell cell = sender as DataGridCell;
  cell.Foreground = new SolidColorBrush(Colors.Red);
}
