我正在用C#为Windows 10编写一个小应用程序,我有一个如下所示的列表视图,它已经在网格中。
然而,我添加到listview的网格没有扩展以填充空间,它只是增长到与绑定到它的字段中包含的数据的长度一样宽。我究竟做错了什么?我不想使用固定字段,我更喜欢使用页面宽度的相对比例。
帮助!

您需要将HorizontalContentAlignment
ListView.ItemContainerStyle
内的ListViewItem
设置为Stretch
。
ListView
的完整XAML如下所示。
<ListView x:Name="ThisList"
Grid.Row="2"
Grid.ColumnSpan="5"
Background="LightBlue"
Margin="5"
ItemsSource="{Binding data}"
IsItemClickEnabled="True"
ItemClick="ThisList_ItemClick">
<ListView.ItemTemplate>
<DataTemplate>
<Grid BorderThickness="1" BorderBrush="Red" >
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Border Background="Aquamarine" Grid.Column="0">
<SymbolIcon Symbol="Folder" HorizontalAlignment="Center" Margin="15 0"/>
</Border>
<Border Background="Yellow" Grid.Column="1">
<TextBlock Text="{Binding FName}" Margin="10" />
</Border>
<Border Background="Cyan" Grid.Column="2">
<TextBlock Text="{Binding FTime}" Margin="10"/>
</Border>
<Border Background="Tomato" Grid.Column="3">
<TextBlock Text="{Binding FSize}" HorizontalAlignment="Right" Margin="10"/>
</Border>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
</ListView>
最后,请参阅我如何添加ItemContainerStyle
仅定位ListViewItem
。

它可能会对你有所帮助。我曾经那样使用过 -
<ScrollViewer ScrollViewer.VerticalScrollBarVisibility="Auto">
<StackPanel>
<ListView x:Name="UserMessageList">
<ListView.ItemTemplate>
<DataTemplate x:DataType="local1:MessageModel">
<StackPanel>
//Add your conrole
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
</ScrollViewer>
