在Elmish.WPFF＃中，如何编写绑定以支持具有不同模型的另一个tabcontrol中的tabcontrol？

如何解决在Elmish.WPFF＃中，如何编写绑定以支持具有不同模型的另一个tabcontrol中的tabcontrol？

作为一个完整的新手（但学习速度很快），我一直在通过Elmish.wpf进行研究，但是我不清楚如何管理放置在另一个TabControl的TabItem上的TabControl。例如，在Xaml中，顶层窗口是：

<Window x:Class="FrontOffice.MainWindow"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:FrontOffice"
             xmlns:doctor="clr-namespace:Doctor"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    
    <Window.Resources>
        <DataTemplate x:Key="DoctorViewTemplate">
            <doctor:DoctorView />
        </DataTemplate>
        <DataTemplate x:Key="NurseViewTemplate">
            <local:NurseView/>
        </DataTemplate>
        <DataTemplate x:Key="MedicalRecordsViewTemplate">
            <local:MedicalRecordsView/>
        </DataTemplate>
        <DataTemplate x:Key="PatientViewTemplate">
            <local:PatientView/>
        </DataTemplate>
        <DataTemplate x:Key="ProvidersViewTemplate">
            <local:ProvidersView/>
        </DataTemplate>
        <local:PropertyDataTemplateSelector x:Key="templateSelector"
                    DoctorViewTemplate="{StaticResource DoctorViewTemplate}"
                    NurseViewTemplate="{StaticResource NurseViewTemplate}" 
                    MedicalRecordsViewTemplate="{StaticResource MedicalRecordsViewTemplate}"
                    PatientViewTemplate="{StaticResource PatientViewTemplate}"
                    ProvidersViewTemplate="{StaticResource ProvidersViewTemplate}"/>                        
    </Window.Resources>
    <Grid>
        <TabControl ItemsSource="{Binding Tabs}" ContentTemplateSelector="{StaticResource templateSelector}">
            <TabControl.ItemContainerStyle>
                <Style TargetType="{x:Type TabItem}">
                    <Setter Property="Header" Value="{Binding Header}" />
                </Style>
            </TabControl.ItemContainerStyle>
        </TabControl>
    </Grid>
</Window>

每个视图：DoctorView，NurseView，MedicalRecordsView等，都有与其类似的自己的标签控件（但具有不同的视图和属性）：

<UserControl x:Class="Doctor.DoctorView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:Doctor"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">
    <UserControl.Resources>
        <DataTemplate x:Key="AppointmentsViewTemplate">
            <local:AppointmentsView />
        </DataTemplate>
        <DataTemplate x:Key="ChartStatusViewTemplate">
            <local:ChartStatusView/>
        </DataTemplate>
        <DataTemplate x:Key="CheckInViewTemplate">
            <local:CheckInView/>
        </DataTemplate>
       
        <local:PropertyDataTemplateSelector x:Key="templateSelector"
                    AppointmentsViewTemplate="{StaticResource AppointmentsViewTemplate}"
                    ChartStatusViewTemplate="{StaticResource ChartStatusViewTemplate}" 
                    CheckInViewTemplate="{StaticResource CheckInViewTemplate}"/>
    </UserControl.Resources>
    <Grid>
        <TabControl ItemsSource="{Binding Tabs}" ContentTemplateSelector="{StaticResource templateSelector}">
            <TabControl.ItemContainerStyle>
                <Style TargetType="{x:Type TabItem}">
                    <Setter Property="Header" Value="{Binding Header}" />
                </Style>
            </TabControl.ItemContainerStyle>
        </TabControl>
    </Grid>
</UserControl>

F＃中最顶端的窗口是 当前 ，定义为：

namespace FrontOfficeModels

open Elmish.WPF
open Elmish

module FrontOffice =

    type DetailType =
        | DoctorView
        | NurseView
        | MedicalRecordsView
        | PatientView
        | ProviderView

    type Tab = { Id: int;  Header: string; Type: DetailType }

   
    type Model =
        { Tabs: Tab list
          Selected: int option }

   
    type Msg =
        | Select of int option
    
    let init () =
           { Tabs = [{Id=0;  Header="Doctor View";              Type=DoctorView} 
                     {Id=1;  Header="Nurse View";               Type=NurseView} 
                     {Id=2;  Header="Medical Records View";     Type=MedicalRecordsView} 
                     {Id=3;  Header="Patient View";             Type=PatientView} 
                     {Id=4;  Header="Provider View";            Type=ProviderView }
                    ]
             Selected = Some 3 }

    let update msg m =
        match msg with
        | Select entityId -> { m with Selected = entityId }

    let bindings () : Binding<Model,Msg> list = [
        "Tabs" |> Binding.oneWay (fun m -> m.Tabs)
    ]

    let designVm = ViewModel.designInstance (init ()) (bindings ())

    let main window =
        Program.mkSimpleWpf init update bindings
        |> Program.withConsoleTrace
        |> Program.runWindowWithConfig
          { ElmConfig.Default with LogConsole = true; Measure = true }
          window

现在，我想我需要将DetailType中的DoctorView，NurseView等更改为单独的模型-因为每个模型现在都具有自己的标签控件和用于数据输入的完全不同的属性，

type DetailType =
        | DoctorView
        | NurseView
        | MedicalRecordsView
        | PatientView
        | ProviderView

，并且我认为我需要使用Elmish.WPF Bindings.SubModel。但是，如果这样做，那么如何重写顶部窗口的绑定？最好怎么做？

谢谢您的帮助。

TIA
