C# WPF获取GridView列中文本框的绑定值

我正在实现一个函数，按列值对

列表视图中的项目进行排序

下面是我的一段XAML代码：

<ListView x:Name="ListView4" SelectedItem="{Binding SelectedRepere}" ItemsSource="{Binding ListeDesReperes}"  Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="4" MouseDoubleClick="ListView_MouseDoubleClick" GridViewColumnHeader.Click="GridViewColumnHeaderClickedHandler" ContextMenuOpening="ListView4_ContextMenuOpening" SelectionChanged="ListView4_SelectionChanged" Visibility="{Binding Grid4Visible, Converter={StaticResource BoolToVisConverter}}" >
                <ListView.ContextMenu>
                    <ContextMenu x:Name="Context4">
                        <MenuItem x:Name="Context4MakeLonger" Header="{x:Static p:Resources.MakeLonger}" Click="Make_Longer"/>
                        <MenuItem x:Name="Context4Search" Header="{x:Static p:Resources.Search}" Click="Search_Detail"/>
                    </ContextMenu>
                </ListView.ContextMenu>
                <ListView.View>

                    <GridView AllowsColumnReorder="true" x:Name="GridView4">
                        <GridViewColumn DisplayMemberBinding="{Binding Path=ID}" Header="ID" Width="50"/>
                        <GridViewColumn DisplayMemberBinding= "{Binding Path=Name}" Header="{x:Static p:Resources.Nom}" Width="200">

                        </GridViewColumn>
                        <GridViewColumn Header="{x:Static p:Resources.QuantiteUnit}" Width="100">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <TextBlock Text="{Binding Path=Quantite}" TextAlignment="Right"/>
                                    </Grid>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="{x:Static p:Resources.QuantiteTot}" Width="100">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <TextBlock Text="{Binding Path=TotalQuantity}" TextAlignment="Right"/>
                                    </Grid>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn DisplayMemberBinding="{Binding Path=Profil}" Header="{x:Static p:Resources.Profil}" Width="100"/>
                        <GridViewColumn DisplayMemberBinding="{Binding Path=Priorite}" Header="{x:Static p:Resources.Priorite}" Width="100"/>
                        <GridViewColumn DisplayMemberBinding="{Binding Path=Matiere}" Header="{x:Static p:Resources.Matiere}" Width="100"/>
                        <GridViewColumn DisplayMemberBinding="{Binding Path=GroupeProfil}" Header="{x:Static p:Resources.GroupeProfil}" Width="100"/>
                        <GridViewColumn DisplayMemberBinding="{Binding Path=Longueur}" Header="{x:Static p:Resources.Longueur}" Width="100">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <TextBlock Text="{Binding Path=Longueur, StringFormat={}{0:#000}}" TextAlignment="Right"/>
                                    </Grid>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>

                        <GridViewColumn Header="{x:Static p:Resources.Weight}" Width="70">
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <TextBlock Text="{Binding Path=Poids, StringFormat=N2}" TextAlignment="Right"/>
                                    </Grid>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Width="140" Header="{x:Static p:Resources.Avancement}">
                            <GridViewColumn.CellTemplate>

                                    <Rectangle Name="PART_Track"  Height="20" Stroke="black" StrokeThickness="1" Fill="{Binding RectangleProgression}" Tag="{Binding Name}" MouseMove="mouseOverProgression">
                                        <Rectangle.ToolTip>
                                            <StackPanel>
                                                <Grid>
                                                    <Grid.ColumnDefinitions>
                                                        <ColumnDefinition/>
                                                        <ColumnDefinition Width="10"/>
                                                        <ColumnDefinition/>
                                                    </Grid.ColumnDefinitions>
                                                    <TextBlock Grid.Column="0" Text="{Binding Path=ToolTipProgressionTb1}" TextAlignment="Left" HorizontalAlignment="Left"/>
                                                    <TextBlock Grid.Column="2" Text="{Binding Path=ToolTipProgressionTb2}" TextAlignment="Right" HorizontalAlignment="Right"/>

                                                </Grid>
                                            </StackPanel>
                                        </Rectangle.ToolTip>
                                    </Rectangle>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                    </GridView>
                </ListView.View>
            </ListView>

这段代码与我在
GridViewColumn
中定义绑定权限的代码一样好（即：Profil、Priorite…）

问题是，当我的专栏中有一些
cellmetplate
和
TextBox
时，我想使用
TextBox
的
displaymberbinding

对于“Longueur”列，我尝试在
GridViewColumn
和
TextBox
中添加绑定，解决了问题，但我认为这不是一个好的解决方案

我该怎么做呢

header = ((System.Windows.Data.Binding)headerClicked.Column.CellTemplate.TextBox.DisplayMemberBinding).Path.Path;

以下是如何从
TextBlock
检索绑定路径：

DataTemplate cellTemplate = headerClicked.Column.CellTemplate;
Grid grid = cellTemplate.LoadContent() as Grid;
TextBlock textBlock = grid.Children.OfType<TextBlock>().FirstOrDefault();
string bindingPath = BindingOperations.GetBinding(textBlock, TextBlock.TextProperty).Path.Path;

DataTemplate-cellTemplate=headerClicked.Column.cellTemplate；
Grid Grid=cellTemplate.LoadContent（）作为网格；
TextBlock TextBlock=grid.Children.OfType（）.FirstOrDefault（）；
string bindingPath=BindingOperations.GetBinding（textBlock，textBlock.TextProperty）.Path.Path；

DataTemplate cellTemplate = headerClicked.Column.CellTemplate;
Grid grid = cellTemplate.LoadContent() as Grid;
TextBlock textBlock = grid.Children.OfType<TextBlock>().FirstOrDefault();
string bindingPath = BindingOperations.GetBinding(textBlock, TextBlock.TextProperty).Path.Path;
