WPF中的C＃ListView，无法查看内容

Question

很快，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。

cur.execute("INSERT INTO testtable (id,name) VALUES (%s, %s)" % row)
TypeError: not enough arguments for format string.

实施是：

 <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>

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。
