Datagrid和组合框 - MVVM和C＃ [英] Datagrid and combobox - MVVM and C#

问题描述

您好，我正在用c＃研究mvvm模式。我有一个问题！

我有一个带有ItemSource（类Order）和SelectedItem（SelectedOrder）的数据网格。

使用select i填充a使用数据网格中的信息形式，但是对于某些值，我需要使用组合框提出一些选择。

组合框的选择不在选定项目中。

如何我可以显示所选数据的详细信息，并让用户可以从价值清单中选择（OPEN，CLOSE，...）。

提前谢谢



我尝试过：

Hello, i'm studying the mvvm pattern with c#. I've a problem!
I have a datagrid with an ItemSource (class "Order") and a SelectedItem ("SelectedOrder").
With a select i fill a form with the information conteined in the datagrid, but for some values i need to proposing some choice with combobox.
The choices of the combobox are not in the selecteditem.
How can I display the detail of my selected article of data and give the possibility to the user to choice from a list of value (OPEN, CLOSE, ...).
Thanks in advance

What I have tried:

This is the view
<pre>
<Grid DataContext="{Binding SelectedOrder}">
...
<Label Content="Customer:" FontSize="12" x:Name="lblState" VerticalAlignment="Top" Grid.Row="2" Grid.Column="2"/>
<ComboBox x:Name="cmbState" FontSize="12" FontWeight="Normal" IsEditable="True"  Grid.Row="2" Grid.Column="3" Text="{Binding state,Mode=TwoWay}">
...
</Grid>

<DataGrid ItemsSource="{Binding Order, IsAsync=True}" SelectedItem="{Binding SelectedOrder, Mode=TwoWay}" Grid.Row="3" AutoGenerateColumns="false" CanUserAddRows="False" CanUserSortColumns="True" CanUserResizeRows="False" IsReadOnly="True" SelectionMode="Single" SelectionUnit="FullRow">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Number" Binding="{Binding numOrder}" Width="1*" />

这是班级订单

This is the class Order

public class Order
    {
        public int id { get; set; }
        public string numOrder { get; set; }
        public string title { get; set; }
        public string state { get; set; }
        public string dateCreation { get; set; }
        public string note { get; set; }
    }
