Silverlight动态获取GridView的 列模板DataTemplate内控件解决方案

Silverlight动态获取GridView的 列模板DataTemplate内控件
  一个GridView的GridViewColumn定制多层表头HeaderCellStyle，并定制对应的模板DataTemplate，
  提供当前GridView对象，
  1，获取模板列DataTemplate里面的控件（条件：并不知道控件的名称）
  2，获取多层表头HeaderCellStyle的层次和每层的控件（这个貌似无法实现）
  请大家提供实现思路

多行表头样式---
<Style x:Key="AuditResultHeaderStyle" TargetType="dataprimitives:GridViewHeaderCell" >
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate>
                            <Grid x:Name="Root">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto" />
                                    <RowDefinition Height="1" />
                                    <RowDefinition Height="Auto" />
                                </Grid.RowDefinitions>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="90" />
                                    <ColumnDefinition Width="1" />
                                    <ColumnDefinition Width="90" />
                                    <ColumnDefinition Width="1" />
                                    <ColumnDefinition Width="90" />
                                    <ColumnDefinition Width="1" /> 
 
                                </Grid.ColumnDefinitions>
                                <TextBlock Text="第一次稽核结果标注汇总" Grid.Row="0" Grid.ColumnSpan="5" Margin="0,4,0,4" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                <Rectangle Fill="#FFC9CACA" Grid.Row="0" Grid.Column="5" HorizontalAlignment="Stretch"/>
                                <Rectangle Fill="#FFC9CACA" Grid.Row="1" Grid.ColumnSpan="6" HorizontalAlignment="Stretch"/>
                                <TextBlock Text="无问题数" Grid.Row="2"  Grid.Column="0" HorizontalAlignment="Center" Margin="0,4,0,4" VerticalAlignment="Center"/>
                                <Rectangle Fill="#FFC9CACA" Grid.Row="2" Grid.Column="1" HorizontalAlignment="Stretch"/>
                                <TextBlock Text="疑点及问题数" Grid.Row="2" Grid.Column="2" Margin="0,4,0,4" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                <Rectangle Fill="#FFC9CACA" Grid.Row="2" Grid.Column="3" HorizontalAlignment="Stretch"/>
                                <TextBlock Text="疑点及问题金额" Grid.Row="2" Grid.Column="4" Margin="0,4,0,4" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                <Rectangle Fill="#FFC9CACA" Grid.Row="2" Grid.Column="5" HorizontalAlignment="Stretch"/>
                            </Grid>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
列定义（引用上的HeaderCellStyle，并定制对应的模板DataTemplate）----
<telerikGridView:GridViewDataColumn HeaderTextAlignment="Left"  
 
                                                        HeaderCellStyle="{StaticResource AuditResultHeaderStyle}">
                    <telerikGridView:GridViewDataColumn.CellTemplate >
                        <DataTemplate>
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="83 " />
                                    <ColumnDefinition Width="*" />
                                    <ColumnDefinition Width="85" />
                                    <ColumnDefinition Width="*" />
                                    <ColumnDefinition Width="85" />
                                </Grid.ColumnDefinitions>
                                <TextBlock Grid.Column="0" Text="{Binding notErrorCount}" VerticalAlignment="Center" TextAlignment="Right"/>
                                <Rectangle Grid.Column="1" Fill="#FFC9CACA" VerticalAlignment="Stretch" Width="1" MinHeight="25"/>
                                <TextBlock Grid.Column="2" Text="{Binding errorAndQuestionCount}" VerticalAlignment="Center" TextAlignment="Right"/>
                                <Rectangle Grid.Column="3" Fill="#FFC9CACA" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Width="1" MinHeight="25"/> 
 
                                <TextBlock Grid.Column="4" Text="{Binding errorAndQuestionMoneyTotal, StringFormat=C,ConverterCulture=zh-CN}" VerticalAlignment="Center" TextAlignment="Right"/>
                            </Grid>
                        </DataTemplate>
                    </telerikGridView:GridViewDataColumn.CellTemplate>
                </telerikGridView:GridViewDataColumn>
