根据组合框的选择保存在数据库的不同表中 [英] save in different tables in the database based on the selection of a combobox

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"/>
</Grid>

向大家问好，

我找不到最终目标的合适解决方案.

在风景优美的MVVM中.

我有一个窗口(用于插入票据的窗口)是一个组合框，可以在其中选择发票类型(即时发票，递延发票，运输单据，报价，交货单等).

并且我将在db中有各自的表(head和body). 

现在，根据您的选择，我可以将数据保存在相关表中.我无法首先在WPF MVVM解决方案实体框架代码中实现它.

=(而且花了几个月的时间，但无济于事.我现在要解决此问题，我在救援前使用了自动映射器，即做了映射表. 

我将一个链接链接到我想在wpf上复制的视频.

hello to all, 

I could not find a suitable solution to my final goal. 

are in a scenery MVVM. 

I have a window (the one for inserting bills) in this window is a combobox where I can choose the types of invoice (invoice immediate, deferred invoice, transport document, quotation, delivery order etc ...) 

and I'll have the respective tables in the db (head and body). 

Now I do based on your choice I can save the data in the related tables. I was not able to implement it in my WPF MVVM solution entity framework code first.

= (And for a few months but to no avail. I do for now to work around this problem, I used automapper ie before the rescue and did the mapping table. 

I put a link to a video of what I would like to replicate on wpf.
