小编Dav*_*ave的帖子

我有以下(缩写)xaml:

<TextBlock Text="{Binding Path=statusMsg, UpdateSourceTrigger=PropertyChanged}"/>

我有一个单身人士课程:

public class StatusMessage : INotifyPropertyChanged
{   
    private static StatusMessage instance = new StatusMessage();

    private StatusMessage() { }

    public static StatusMessage GetInstance()
    {
        return instance;
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void OnPropertyChanged(string status)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(status));
        }
    }

    private string statusMessage;
    public string statusMsg
    {
        get
        {
            return statusMessage;
        }
        set
        {
            statusMessage = value;
            OnPropertyChanged("statusMsg");
        }
    }
}

在我的主窗口构造函数中:

StatusMessage testMessage = StatusMessage.GetInstance();
testMessage.statusMsg = "This is …

好吧,我的C#WPF ListView控件存在更多问题.这里充满了荣耀:

<Window x:Class="ebook.SearchResults" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"Title="ISBNListView" Height="503" Width="1004">
<Grid>
    <ListView Name="listView1" Margin"22,30,33,28" MouseDoubleClick="getSelectedItem" >

        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="ISBN" Width="150" DisplayMemberBinding="{Binding ISBN}"/>
                    <GridViewColumn Header="Title" Width="350" DisplayMemberBinding="{Binding Title}"/>
                    <GridViewColumn Header="Author" Width="350" DisplayMemberBinding="{Binding Author}" />
                </GridView.Columns>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

我用以下内容填充listView:

XDocument xdoc = XDocument.Load(GlobalVars.docPath + "\\tempSearchResults.xml");
        var items = from item in xdoc.Descendants("Book")
                    select new
                    {
                        ISBN = item.Element("ISBN").Value,
                        Title = item.Element("Title").Value,
                        AuthTexts = item.Element("Author").Value
                    };
        foreach (var item in items)
        {
            listView1.Items.Add(new { ISBN = item.ISBN, Title = item.Title, Author …
