WPF-将TabControl的Itemsource绑定到单个对象

Question

我有一个Wpf DatarGrid，它绑定到客户列表。在这里，我想要的是当我在datagrid中选择一个客户并单击“更新”按钮时，将打开一个窗口。这个新窗口有一个标签控件。然后，当我第二次单击datagrid中另一个用户的更新时，第二个选项卡应在此已打开的新窗口中打开。为此，我想将Tab控件仅绑定到Selected Customer行，而不是ObservableCollection或List。但是，当我将SelectedCustomer绑定到Itemssource属性时，由于标题不起作用，因此它不起作用。对于标题，我有一个Itemtemplate，在其中将文本块绑定到SelectedCustomer属性（例如name）。

对此有什么解决方案？

我的数据网格看起来像这样-

<DataGrid Width="700" Height="500" Margin="20" AutoGenerateColumns="False" IsReadOnly="True" SelectedItem="{Binding SelectedCustomer}" ItemsSource="{Binding Customers}">
                    <DataGrid.Columns>
                        <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}"></DataGridTextColumn>
                        <DataGridTextColumn Header="Last Name" Binding="{Binding LastName}"></DataGridTextColumn>
                        <DataGridTemplateColumn>
                            <DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <Button Margin="5" Click="Update_Clicked">Update</Button>
                                </DataTemplate>
                            </DataGridTemplateColumn.CellTemplate>
                        </DataGridTemplateColumn>
                        <DataGridTemplateColumn>
                            <DataGridTemplateColumn.CellTemplate>
                                <DataTemplate>
                                    <Button Margin="5">Delete</Button>
                                </DataTemplate>
                            </DataGridTemplateColumn.CellTemplate>
                        </DataGridTemplateColumn>

                    </DataGrid.Columns>
                </DataGrid>

在这里您可以看到selecteditem属性绑定到SelectedCustomer。现在选项卡控制窗口看起来像这样-

 <TabControl Name="UserTabs" ItemsSource="{Binding}">


            <TabControl.ItemTemplate>
                <DataTemplate DataType="TabItem">
                    <TextBlock Text="{Binding FirstName}"></TextBlock>
                </DataTemplate>
            </TabControl.ItemTemplate>
            <TabControl.ContentTemplate>
                <DataTemplate>
                    <Grid Height="226"  Margin="4">
                        <Grid.Resources>
                            <Style TargetType="{x:Type TextBlock}">
                                <Setter Property="Margin" Value="2,2,2,2" />
                                <Setter Property="HorizontalAlignment" Value="Center"></Setter>
                                <Setter Property="FontSize" Value="20"></Setter>
                            </Style>
                        </Grid.Resources>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                            <ColumnDefinition></ColumnDefinition>
                        </Grid.ColumnDefinitions>
                        <Grid.RowDefinitions>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                            <RowDefinition></RowDefinition>
                        </Grid.RowDefinitions>

                        <TextBlock Grid.Column="0" Grid.Row="0">First Name :</TextBlock>
                        <TextBlock Grid.Column="0" Grid.Row="1">Last Name :</TextBlock>
                        <TextBlock Grid.Column="0" Grid.Row="2">Email Address :</TextBlock>
                        <TextBlock Grid.Column="0" Grid.Row="3" Grid.ColumnSpan="2" HorizontalAlignment="Left"><Hyperlink>Address :</Hyperlink></TextBlock>
                        <TextBlock Grid.Column="0" Grid.Row="4">City :</TextBlock>
                        <TextBox Grid.Column="1" Grid.Row="0" Text="{Binding FirstName}"></TextBox>
                        <TextBox Grid.Column="1" Grid.Row="1" Text="{Binding LastName}"></TextBox>
                        <TextBox Grid.Column="1" Grid.Row="2" Text="{Binding EmailAddress}"></TextBox>
                        <TextBox Grid.Column="1" Grid.Row="4" Text="{Binding City}"></TextBox>


                        <TextBlock Grid.Column="2" Grid.Row="0">State :</TextBlock>
                        <TextBlock Grid.Column="2" Grid.Row="1" Grid.ColumnSpan="2" HorizontalAlignment="Center"><Hyperlink>Orders :</Hyperlink></TextBlock>
                        <TextBlock Grid.Column="2" Grid.Row="2"></TextBlock>
                        <TextBlock Grid.Column="2" Grid.Row="3"></TextBlock>
                        <TextBlock Grid.Column="2" Grid.Row="4"></TextBlock>
                        <TextBlock Grid.Column="2" Grid.Row="5"></TextBlock>
                        <TextBox Grid.Column="3" Grid.Row="0" Text="{Binding State}"></TextBox>
                        <TextBlock Grid.Column="3" Grid.Row="1"></TextBlock>
                        <TextBlock Grid.Column="3" Grid.Row="2"></TextBlock>
                        <TextBlock Grid.Column="3" Grid.Row="3"></TextBlock>
                        <TextBlock Grid.Column="3" Grid.Row="4"></TextBlock>
                        <TextBlock Grid.Column="3" Grid.Row="5"></TextBlock>

                    </Grid>
                </DataTemplate>
            </TabControl.ContentTemplate>

        </TabControl>   

如您所见，我已经使用Itemssource = {Binding}，这意味着Itemssource绑定到SelectedCustomer，因为在我后面的代码中已设置

this.datacontext = SelectedCustomer

然后在ItemTemplate和Content Template中，使用

将文本块和文本框绑定到SelectedCustomer的属性。

{Binding <PropertyName>}
