我希望在运行中动态改变DataGrid.RowDetailsTemplate模板内容，增加或减少一个TextBlock，应该怎样做？
        <data:DataGrid Name="list" >
            <data:DataGrid.RowDetailsTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock Text="            类型:" />
                        <TextBlock Text="{Binding id}" >
                    </StackPanel>
                </DataTemplate>
             </data:DataGrid.RowDetailsTemplate>
        </data:DataGrid >

请问我使用了XamlReader.Load，怎么才能修改控件的动画样式呢？

现在我在style中定义了新的样式，如果我使用XamlReader.Load动态添加了，样式又变回默认的了，该如何修改呢？

例如下面的样式代码，该如何使用xamlreader载入呢？

<Setter Property="Foreground" Value="#FF444444" />
        <Setter Property="Background" Value="#FFD4E9F7" />
        <Setter Property="HorizontalContentAlignment" Value="Center" />
        <Setter Property="VerticalContentAlignment" Value="Bottom" />
        <Setter Property="FontSize" Value="11.5" />
        
        <Setter Property="IsTabStop" Value="False" />
        <Setter Property="SeparatorBrush" Value="#FFAAAAAA" />
        <Setter Property="Padding" Value="8,40,0,0" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="localprimitives:DataGridColumnHeader">
                    <Grid x:Name="Root">
                        <VisualStateManager.VisualStateGroups>
