silverlight后台动态创建模板列问题

<Grid>

                                <Grid.Resources>

                                    <my:Day30Style1Converter x:Key="Day30Style1Converter"></my:Day30Style1Converter>

                                    <my:Day30Style2Converter x:Key="Day30Style2Converter"></my:Day30Style2Converter>

                                    <Style x:Key="todaystyle" TargetType="Rectangle" >

                                        <Setter Property="Fill" Value="{Binding Converter={StaticResource Day30Style1Converter}}"></Setter>

                                        <Setter Property="Grid.Column" Value="{Binding Converter={StaticResource Day30Style2Converter}}"></Setter>

                                    </Style>


                                    <Style x:Key="daystyle" TargetType="Rectangle" >

                                        <Setter Property="Fill" Value="#FFC9CACA"></Setter>

                                    </Style>


                                </Grid.Resources>

                                <Grid.RowDefinitions>

.......

</grid>

这是前台xaml代码 ，如何把这个Grid.Resources 这个节点里面的内容也在后台中写出来。。。

这个是我写的Demo
前台

 <Grid x:Name="LayoutRoot"> 

        <Grid.RowDefinitions>

            <RowDefinition Height="40"></RowDefinition>

            <RowDefinition Height="*"></RowDefinition>
