WPF如何将新数据放在旧数据下的ListView中的某行中
WPF How to put new data in some row in ListView under old data
我在使用 Listview 时遇到了问题，我真的不知道该怎么办。我在 ListView 中创建了 GridView，现在我必须调整 listview 中的数据，
我要做的就是在现有行中写入新的数据信息
新数据必须在同一行，颜色必须不同，新数据必须在旧数据之下。旧数据不变，只有2列和4列数据交叉
我的Xaml:
<ListView x:Name="lbPersonList" Margin="30,98.4,362,150" ScrollViewer.VerticalScrollBarVisibility="Visible"
AlternationCount="2" >
<ListView.View>
<GridView>
<GridViewColumn>
<GridViewColumnHeader Content="Product">
</GridViewColumnHeader>
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" FontSize="18px" FontFamily="Arial"
FontWeight="Normal" Width="670" TextAlignment="Left"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn >
<GridViewColumnHeader Content="Unit price, €"
HorizontalAlignment="Right">
</GridViewColumnHeader>
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Age}" FontSize="18px" FontFamily="Arial"
FontWeight="Normal" Width="100" TextAlignment="Right"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn >
<GridViewColumnHeader Content="Quantity"

我也用public class VisibilityConverter : IValueConverter
我会说你只需要修改每一列的单元格模板。创建一个垂直的 StackPanel 并将原始文本作为第一行，将红色文本作为第二行。您是否显示第二行将与可见性标志相关联。就像您在第一行删除删除线一样。应该很简单。您只需要将属性添加到您的 Person class.
我不会为你写东西，但看起来很简单
<StackPanel Orientation="Vertical">
<Grid>
<TextBlock Text="{Binding Row1} VerticalAlignment="Center" />
<Rectangle Height="1" Fill="Red" VerticalAlignment="Center" Visibility={Binding Row2Visibility} />
</Grid>
<TextBlock Foreground="Red" Text="{Binding Row2} Visibility={Binding Row2Visibility} />
</StackPanel>
这就像我要做的 5 秒模拟 :)。垂直堆栈面板包含第一行和第二行文本。第 2 行文本具有与其相关的可见性...第 1 行，我将其放在网格内，因此很容易划线。如果你想通过 "right" 方式进行删除，那将需要克隆系统字体并添加删除线......当真正的删除线只是一条线时，所以没什么大不了的。删除线的可见性显然与第二行文本的可见性相同。它们要么都可见，要么都折叠。
