使用CanUserAddRows为DataGrid设置样式化新行

Question

我需要在DataGrid为CanUserAddRows设置一行 CanUserAddRows 。 ItemsSource为DataGrid我使用DataTable.DefaultView我尝试：

<DataGrid IsReadOnly="false" CanUserAddRows="True">
  <DataGrid.Resources>
    <Style TargetType="{x:Type DataGridCell}" BasedOn="{StaticResource {x:Type DataGridCell}}">
      <Style.Triggers>
        <DataTrigger Binding="{Binding Path=.}" Value="{x:Null}">
          <Setter Property="Background" Value="Tomato"/>
        </DataTrigger>
      </Style.Triggers>
    </Style>
  </DataGrid.Resources>
  <DataGrid.Columns>
    <DataGridTextColumn Width="*" Binding='{Binding Path=Col1}' Header="Col1" />
    <DataGridTextColumn Width="*" Binding='{Binding Path=Col2}' Header="Col2" />
    <!-- more columns -->
  </DataGrid.Columns>
</DataGrid>

我找到了这个问题的答案！

需要.NET FrameWork 4.5

set Trigger.Property = IsNewItem和Trigger.Value = true ：

          <Style TargetType="{x:Type DataGridRow}" BasedOn="{StaticResource {x:Type DataGridRow}}">
            <Style.Triggers>
              <Trigger Property="DataGridRow.IsNewItem" Value="true">
                <Setter Property="DataGridCell.Background" Value="Tomato"/>
              </Trigger>
            </Style.Triggers>
          </Style>
