我是WPF的新手。我有两个表SalesRep和Item，我有datagrid我需要在wpf datagrid中一次合并地显示两个表列。两个表都没有关系。

<Grid><DataGrid Name="salesrepGrid1" ItemsSource="{Binding SalesReps}" ItemSource="{Binding Items}" AutoGenerateColumns="False">

正确答案可能不是您想要的答案，您需要构建一个能够正确建模数据的数据模型，如果您这样做，那么您不再需要多个来源，就像拥有单一数据模型一样

例如

XAML：

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfApplication1"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <x:Array x:Key="team" Type="local:SalesTeam">
            <local:SalesTeam>
                <local:SalesTeam.Reps>
                    <local:SalesRep Name="A" Pay="5.2" Quota="50" />
                    <local:SalesRep Name="B" Pay="5.2" Quota="50" />
                    <local:SalesRep Name="C" Pay="5.2" Quota="50" />
                </local:SalesTeam.Reps>
                <local:SalesTeam.Items>
                    <local:SalesItem Name="Rocks" Qty="50" Value="1"/>
                    <local:SalesItem Name="Paper" Qty="50" Value="1"/>
                    <local:SalesItem Name="Sissros" Qty="50" Value="1"/>
                </local:SalesTeam.Items>
            </local:SalesTeam>
            <local:SalesTeam >
                <local:SalesTeam.Reps>
                    <local:SalesRep Name="1" Pay="5.2" Quota="50" />
                    <local:SalesRep Name="2" Pay="5.2" Quota="50" />
                    <local:SalesRep Name="3" Pay="5.2" Quota="50" />
                </local:SalesTeam.Reps>
                <local:SalesTeam.Items>
                    <local:SalesItem Name="Row" Qty="50" Value="1"/>
                    <local:SalesItem Name="Sham" Qty="50" Value="1"/>
                    <local:SalesItem Name="Bow" Qty="50" Value="1"/>
                </local:SalesTeam.Items>
            </local:SalesTeam>
        </x:Array>
    </Window.Resources>
    <ListView ItemsSource="{Binding Mode=OneWay, Source={StaticResource team}}" >
        <ListView.ItemTemplate>
            <DataTemplate>
                <TabControl>
                    <TabItem Header="Reps">
                        <DataGrid ItemsSource="{Binding Reps}" />
                    </TabItem>
                    <TabItem Header="Items">
                        <DataGrid ItemsSource="{Binding Items}"/>
                    </TabItem>
                </TabControl>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Window>

型号：

public class SalesTeam 
{
    //details on team
    public ObservableCollection<SalesRep> Reps { get; } = new ObservableCollection<SalesRep>();

    public ObservableCollection<SalesItem> Items { get; } = new ObservableCollection<SalesItem>();
}


public class SalesRep : INotifyPropertyChanged
{

    private string name;

    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Name)));
        }
    }


    private int quota;

    public int Quota
    {
        get { return quota; }
        set
        {
            quota = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Quota)));
        }
    }
    private double pay;

    public double Pay
    {
        get { return pay; }
        set
        {
            pay = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Pay)));
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
}

public class SalesItem : INotifyPropertyChanged
{
    private string name;

    public string Name
    {
        get { return name; }
        set
        {
            name = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Name)));
        }
    }


    private int qty;

    public int Qty
    {
        get { return qty; }
        set
        {
            qty = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Qty)));
        }
    }
    private double val;

    public double Value
    {
        get { return val; }
        set
        {
            val = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(Value)));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

在这个例子中，我在XAML中构建了View Model，但你可以从任何地方获取它，这里我只是使用一组团队来填充Items控件并为每个数据网格模板化Tab控件
