} 我想要的是将一个ObservaleCollection的一些值绑定到一个DataGridTextColumn，将另一个ObservaleCollection的一些值绑定到另一个DataGridTextColumn，等等

这是Datagrid，绑定的目标：

<DataGrid x:Name="DonneesBrutes" IsReadOnly="True" ItemsSource="{Binding Path=.cmpc}" Margin="10,65,0,0" AutoGenerateColumns="False" EnableRowVirtualization="True" RowDetailsVisibilityMode="VisibleWhenSelected">
        <DataGrid.RowStyle>
            <Style TargetType="{x:Type DataGridRow}">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding .Remarque}" Value="{x:Null}">
                        <Setter Property="Visibility" Value="Collapsed"></Setter>
                    </DataTrigger>
                </Style.Triggers>
            </Style>
        </DataGrid.RowStyle>
            <DataGrid.Columns>
                <DataGridTextColumn x:Name="PMRQ" Width="*" Binding="{Binding Path=.PMID}" Header="PMID"></DataGridTextColumn>
                <DataGridTextColumn x:Name="LibellePMRQ" Width="*" Binding="{Binding Path=.LibelléTOTApres}" Header="Libellé PMRQ"></DataGridTextColumn>
                <DataGridTextColumn x:Name="Ligne" Width="*"     Binding="{Binding Path=.Remarque}" Header="Ligne" IsReadOnly="True"></DataGridTextColumn>
                <DataGridTextColumn x:Name="OTM" Width="*" Binding="{Binding Path=.TOTMPMRQ}" Header="OTM"></DataGridTextColumn>
                <DataGridTextColumn x:Name="TOTM" Width="*" Binding="{Binding Path=.SiModifie}" Header="TOTM"></DataGridTextColumn>
                <DataGridTextColumn x:Name="LibelleTOTM" Width="*" Binding="{Binding Path=.LibelléTOTApres}" Header="Libellé OTM"></DataGridTextColumn>
                <DataGridTextColumn x:Name="GA" Width="*" Binding="{Binding Path=.Groupe_D_alerte}" Header="GA"></DataGridTextColumn>
                <DataGridTextColumn x:Name="Discipline" Width="*" Binding="{Binding Path=.NomTable}" Header="Discipline"></DataGridTextColumn>
                <DataGridTextColumn x:Name="DisciplineSubstituee" Width="120" Binding="{Binding Path=.NomChamp}" Header="Discipline Substituée"></DataGridTextColumn>
            </DataGrid.Columns>
</DataGrid>
第一个DataGridTextColumn是从D98DetailsCollection绑定的，第二个是从ResultatCollection绑定的，等等。条件如下：作为每个ObservableCollection的公共列的属性TOTMPMRQ相等

例如，对于像123456789这样的TOTMPMRQ，我想在TOTMPMMRQ等于123456789的第一个DataGridTextColumn中绑定D98Details集合的PMRQ值，然后在TOTMPMRQ仍然等于123456789的第二个DataGridTextColumn中绑定ResultatCollection的libellePMRQ值，etc用于每个DataGridTextColumn，从几个ObservableCollections获取一行值

我的主要困难是使这个条件。目前，DataGrid只在ObservableCollection之后打印ObservableCollection，而不是组合结果

我希望我的解释不会太混乱，如果需要的话，我总是可以编辑我的帖子，不要犹豫问我更多或者更少

提前感谢你的帮助

EDIT1:

我创建了一个类TestCollectionList，它继承了一个名为TestCollection的ObservableCollection，如下所示：

    D98DetailsCollection = new ObservableCollection<D98Details>(_BDDInterneEntities.D98Details);
    D675Collection = new ObservableCollection<D675>(_BDDInterneEntities.D675);
    cmpc = new CompositeCollection();

    CollectionContainer cc1 = new CollectionContainer();
    CollectionContainer cc2 = new CollectionContainer();
    CollectionContainer cc3 = new CollectionContainer();
    CollectionContainer cc4 = new CollectionContainer();
    cc1.Collection = ResultatCollection;
    cc2.Collection = D98EquipementsCollection;
    cc3.Collection = D98DetailsCollection;
    cc4.Collection = D675Collection;
    cmpc.Add(cc1);
    cmpc.Add(cc2);
    cmpc.Add(cc3);
