ItemsControl的数据绑定...绑定到当前项目不工作 [英] ItemsControl data binding... binding to the current item isn't working

问题描述

我有以下ItemsControl的网页...

I have the following ItemsControl page...

<Page x:Class="Kiosk.View.ItemListView"
      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:Converter="clr-namespace:Kiosk.Converter" 
      mc:Ignorable="d" 
      d:DesignHeight="300" d:DesignWidth="300"
      Margin="10"
      Title="ItemListView">
    <StackPanel>
        <Button Width="130" Height="130" Style="{StaticResource DarkButton}" 
                Command="BrowseBack" Content="Back" HorizontalAlignment="Left" Margin="0,0,0,5"/>
        <ItemsControl ItemsSource="{Binding EventClassSummaries}">
            <ItemsControl.Resources>
                <Converter:OxiStringConverter x:Key="oxiStringConverter" />
            </ItemsControl.Resources>
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel Height="1000" Width="900" Orientation="Horizontal" />
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Button Content="{Binding Path=Name}"
                            Style="{StaticResource DarkButton}"
                            Height="42"
                            Width="440"
                            FontSize="12pt"
                            Margin="4"/>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </StackPanel>
</Page>

的 EventClassSummaries 工作正常，因为我让我的总结面板按钮的右边数，数据从一个WCF服务，以及个别项目采购如下（从服务端）

The EventClassSummaries is working correctly, as I am getting the right number of buttons in my wrap-panel, the data is sourced from a WCF service, and the individual items are as follows (from the service end)

[DataContract]
public class EventClassSummary
{
    [DataMember] public string Category;
    [DataMember] public char Displayed;
    [DataMember] public int Id;
    [DataMember] public string Name;
    [DataMember] public char Status;
}

我的问题是按钮不会显示在名称绑定和我刚刚得到的空白。

The problem I have is the Buttons do not display the Name binding and I just get blanks.

奇怪这是工作在周五，但我不得不重建服务，并添加一些额外的方法（虽然我没有接触到有关此人！？）

Oddly this was working on Friday, but I've had to rebuild the service and add some additional methods (although I didn't touch the ones relevant to this!?)

没有任何人有想法，我觉得有点奇怪，这用来工作（我甚至它demo'ed到下午的）

Does anyone have ideas, I find it a bit strange that this used to work (I even demo'ed it to PM's)

推荐答案

有关数据绑定与WPF工作，你需要改变你的字段属性。

For DataBinding to work with WPF, you need to change your fields to properties.

所以变化：

[DataMember] public string Name;

到

public string _Name;
[DataMember]
public string Name
{
    get { return _Name; }
    set { _Name = value; }
}

边注：希望你不介意我preaching，但它不是好的做法在presentation层被引用您的数据传输类 - 你应该想想分离图层。

Side note: Hope you don't mind me preaching, but it is not good practice to be referencing your data transfer classes in the presentation layer - you should think about separating your layers.
