wpf网格中的数据值未正确对齐

我正在使用wpf数据网格。我希望数据在网格中正确且居中对齐。目前我正在使用Style setter属性，但没有任何东西适合我

private void DgvInvoice_CellEditEnding(object sender, DataGridCellEditEndingEventArgs e)
        {

                    DataGridColumn nextColumn = DgvInvoice.ColumnFromDisplayIndex(7); // Display Index 7 is Amount Colum in the grid 

                    DataGridRow row = (DataGridRow)DgvInvoice.ItemContainerGenerator.ContainerFromItem(new DataGridCellInfo(DgvInvoice.SelectedItem, nextColumn).Item);

                    DataGridCellsPresenter presenter = GetVisualChild<DataGridCellsPresenter>(row);

                    DataGridCell gridCell = presenter.ItemContainerGenerator.ContainerFromIndex(7) as DataGridCell;
                    if (gridCell != null)
                    {

                        if (d != 0)
                        {
                            gridCell.Content = String.Format("{0:#,0}", d);
                        }
                        else { gridCell.Content = string.Empty; }

                        Style s = new Style();
                        gridCell.Height = 29;
                        s.Setters.Add(new Setter(TextBox.TextAlignmentProperty, TextAlignment.Right));
                        s.Setters.Add(new Setter(TextBox.VerticalContentAlignmentProperty, VerticalAlignment.Center));
                        gridCell.Style = s;
                    }
                }

private void DgvInvoice_CellEditEnding（对象发送方，DataGridCellEditEndingEventArgs e）
{
DataGridColumn nextColumn=DgvInvoice.ColumnFromDisplayIndex（7）；//显示索引7是网格中的数量列
DataGridRow行=（DataGridRow）DgvInvoice.ItemContainerGenerator.ContainerFromItem（新DataGridCellInfo（DgvInvoice.SelectedItem，nextColumn）.Item）；
DataGridCellsPresenter=GetVisualChild（行）；
DataGridCell gridCell=presenter.ItemContainerGenerator.ContainerFromIndex（7）作为DataGridCell；
if（gridCell！=null）
{
如果（d！=0）
{
gridCell.Content=String.Format（“{0:#，0}”，d）；
}
else{gridCell.Content=string.Empty；}
样式s=新样式（）；
网格单元高度=29；
s、 添加（新的Setter（TextBox.TextAlignmentProperty，TextAlignment.Right））；
s、 添加（新的Setter（TextBox.VerticalContentAlignmentProperty，VerticalAlignment.Center））；
Style=s；
}
}

试试这个

Style alignStyle = new Style(typeof(DataGridCell));
alignStyle.Setters.Add(new  Setter(DataGridCell.WidthProperty, 20.0));
alignStyle.Setters.Add(new Setter(DataGridCell.HorizontalAlignmentProperty,HorizontalAlignment.Center));
alignStyle.Setters.Add(new  Setter(DataGridCell.VerticalAlignmentProperty,VerticalAlignment.Center));
YouDataGridName.Style = alignStyle;

我只为你准备了xaml风格

    <Style x:Key="GridCellStyle" TargetType="{x:Type TextBlock}">
        <Setter Property="HorizontalAlignment" Value="Right" />
        <Setter Property="VerticalAlignment" Value="Right" />
    </Style>

 <DataGridTextColumn Header="Betrag" MinWidth="125"
                Binding="{Binding Path=Betrag, Mode=OneWay, StringFormat=#\,##0.00}"
                ElementStyle="{StaticResource GridCellStyle}" />

注意：此处的标题要求使用“网格”，它与“数据网格”不同
