问题描述

我必须创建传递具有一对多关系的实体的通用视图模型.我将解释:我的窗口:

<Window x:Class="Invoice_Example_Brux.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:invoiceExampleBrux="clr-namespace:Invoice_Example_Brux"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
    <invoiceExampleBrux:MainWindowViewModel/>
</Window.DataContext>
<Grid>
    <TextBox HorizontalAlignment="Left" Height="23" Margin="174,78,0,0" TextWrapping="Wrap" Text="{Binding MyModel.Name}" VerticalAlignment="Top" Width="120"/>
    <Label Content="Id" HorizontalAlignment="Left" Margin="10,53,0,0" VerticalAlignment="Top"/>
    <TextBox HorizontalAlignment="Left" Height="23" Margin="10,78,0,0" TextWrapping="Wrap" Text="{Binding MyModel.Id}" VerticalAlignment="Top" Width="120"  IsReadOnly="True"/>
    <Label Content="Number" HorizontalAlignment="Left" Margin="322,52,0,0" VerticalAlignment="Top"/>
    <TextBox HorizontalAlignment="Left" Height="23" Margin="322,78,0,0" TextWrapping="Wrap" Text="{Binding MyModel.Number}" VerticalAlignment="Top" Width="120"/>
    <Label Content="Name" HorizontalAlignment="Left" Margin="174,53,0,0" VerticalAlignment="Top"/>
    <Button Content="Save" HorizontalAlignment="Left" Margin="211,288,0,0" VerticalAlignment="Top" Width="75" Command="{Binding SaveCommand}"/>
    <ComboBox
        SelectionChanged="Selector_OnSelectionChanged"
              HorizontalAlignment="Left" Margin="180,38,0,0" VerticalAlignment="Top" Width="120"                  
              DisplayMemberPath="Name"
              ItemsSource="{Binding DocumentType,UpdateSourceTrigger=PropertyChanged}"/>
    <Label Content="Type Document" HorizontalAlignment="Left" Margin="192,12,0,0" VerticalAlignment="Top"/>
