无法显示 List<MyClass>作为我的 ItemsControl 和 StackPanel 视图的列之一? [英] Unable to display a List<MyClass> as one of the columns of my view with ItemsControl and StackPanel?
问题描述
我有以下课程:
public class Order
{
public string OrderName { get; set; }
public List<Parts> PartsList { get; set; }
}
public class Parts
{
public string PartName { get; set; }
public double PartQuantity { get; set; }
}
在我的代码中,我创建了一个 Order 对象列表
In my code I create a list of Order objects
List<Order> myOrders;
我想以某种方式向用户显示所有这些,例如使用元素的堆栈面板,其中第一个是用于显示 OrderName 的 TextBox,第二个是用于显示部件列表的 Datagrid?
I would like to display all of this to the user somehow, like using a stack panel of elements where the first is a TextBox to display OrderName and the second is a Datagrid to display the list of Parts?
老实说,我正在尝试许多不同的东西(我对使用什么类型的控件没有要求),但我永远无法让 PartsList 正确显示(要么我什么也没得到,要么我向用户显示集合".
Honestly I am trying many different things (I have no requirements on what type of controls to use) but I can never get the PartsList to show correctly (either I get nothing OR I get "Collection" show to the user.
目标是看到这样的东西:
The goal would be to see something like this:
Order1 Part1 7
Part2 12
Order2 Part1 100
Part2 1
Part3 58
这是我今天拥有的 XAML,我真的认为它会起作用:
This is the XAML I have today and I really thought it would work:
<ItemsControl x:Name="visual"
ItemsSource="{Binding myOrders}"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch"
Margin="0,397,37,31" Grid.Row="1" Height="172">
<ItemsControl.ItemTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding }"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding OrderName}"
Margin="10" />
<ItemsControl ItemsSource="{Binding PartsList}"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Text="{Binding PartName}"
TextAlignment="Center" />
<TextBlock Grid.Column="1"
Text="{Binding PartQuantity}"
TextAlignment="Center" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
有人看到这段代码有什么问题吗?
Does anyone see what is wrong with this code?
推荐答案
您有一个额外的不必要的 ItemsControl
.带有 ItemsSource="{Binding}"
的那个.
You have an extra unnecessary ItemsControl
. The one with ItemsSource="{Binding}"
.
因此假设 myOrders
是一个包含 Order
集合的属性,这应该可以工作:
So assuming that myOrders
is a property which holds a collection of Order
s this should work:
<ItemsControl x:Name="visual"
ItemsSource="{Binding myOrders}"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch" Margin="0,397,37,31"
Grid.Row="1" Height="172">
<ItemsControl.ItemTemplate>
<!-- This defines the DataTemplate to display one Order object-->
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding OrderName}"
Margin="10" />
<ItemsControl ItemsSource="{Binding PartsList}"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch">
<ItemsControl.ItemTemplate>
<!-- This defines the DataTemplate to display one Parts object-->
<DataTemplate>
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Text="{Binding PartName}"
TextAlignment="Center" />
<TextBlock Grid.Column="1"
Text="{Binding PartQuantity}"
TextAlignment="Center" />
</Grid>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
