WPF中的C＃ListView，无法查看内容

Shortly, I'm new to grid and WPF and for some reason I cannot see my content within my ListView and I'm pretty much sure that Grid causes it.

不久，我是网格和WPF的新手，由于某种原因，我无法在ListView中看到我的内容，而且我非常确定Grid会导致它。

 <Grid Canvas.Left="223" Canvas.Top="228">
        <Grid.RowDefinitions>
            <RowDefinition Height="9*"/>
            <RowDefinition Height="28*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="8*"/>
            <ColumnDefinition Width="21*"/>
            <ColumnDefinition Width="29*"/>
            <ColumnDefinition Width="29*"/>
        </Grid.ColumnDefinitions>
        <ListView HorizontalAlignment="Left" Height="123" VerticalAlignment="Top" Width="589" Name="LibraryList" Margin="-188,-76,-141.001,-10" IsEnabled="False" Grid.ColumnSpan="4" Grid.RowSpan="2" >
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="Item Name" DisplayMemberBinding="{Binding ItemName}" Width="70"/>
                    <GridViewColumn Header="Copy Number" DisplayMemberBinding="{Binding CopyNumber}" Width="85"/>
                    <GridViewColumn Header="Guid" DisplayMemberBinding="{Binding Guid}" Width="100"/>
                    <GridViewColumn Header="Print Date" DisplayMemberBinding="{Binding Date}" Width="90"/>
                    <GridViewColumn Header="Best Seller" DisplayMemberBinding="{Binding BestSeller}" Width="90"/>
                    <GridViewColumn Header="Category" DisplayMemberBinding="{Binding Category}" Width="70"/>
                    <GridViewColumn Header="Sub Category" DisplayMemberBinding="{Binding SubCategory}" Width="80"/>
                </GridView>
            </ListView.View>
        </ListView>
    </Grid>

The implementation is:

实施是：

ManageCtors.InitJournal(int.Parse(copyNumber.Text), itemName.Text, DateTime.Parse(TimePrinted.Text), int.Parse(Guid.Text), (JournalCategory)Enum.Parse(typeof(JournalCategory), SubCategory.Text));

//Add to ListView
string[] row = { itemName.Text, copyNumber.Text, Guid.Text , TimePrinted .Text, Category.Text , SubCategory.Text = "None" };
ListViewItem _listViewItem = new ListViewItem();
_listViewItem.Content = row;
LibraryList.Items.Add(_listViewItem.Content);

Any Idea?
BTW: Sometimes I get a message: input was not in the correct format.

任何想法？顺便说一句：有时我收到一条消息：输入格式不正确。

The data you are binding to is an array of strings, but in each of the GridViewColumn's you are binding by name. This is probably the problem.

您绑定的数据是一个字符串数组，但在每个GridViewColumn中，您都按名称绑定。这可能是个问题。

You would be best to model the data row out to its own class and set an instance of the class to the ListViewItem.Content property.

您最好将数据行建模到其自己的类，并将该类的实例设置为ListViewItem.Content属性。

public class ItemData
{
    public string ItemName { get; set; }
    public int CopyNumber { get; set; }
    public Guid Guid { get; set; }
    public DateTime Date { get; set; }
    public string BestSeller { get; set; }
    public string Category { get; set; }
    public string Subcategory { get; set; }
}


ItemData row = new ItemData { 
            // set each property value 
        };
ListViewItem _listViewItem = new ListViewItem();
_listViewItem.Content = row;
LibraryList.Items.Add(_listViewItem.Content); // not sure if you need content here

I think you would also be better off binding the ItemsSource on the ListView rather than adding items directly on to the ListView Items collection.

我认为你最好还是在ListView上绑定ItemsSource，而不是直接在ListView Items集合上添加项目。

ObservableCollection<ItemData> items = new ObservableCollection<ItemData>();
// add your ItemData instances to the items collection
LibraryList.ItemsSource = items;

You would also be better off following the MVVM pattern, of which there is a lot of advice on * and elsewhere to get you started.

您最好还是遵循MVVM模式，其中有很多关于*和其他地方的建议可以帮助您入门。
