Vertical scroll bar does not appear when the gridview items exceeded the display height
提问by Artur Carvalho
I place the following statements in the second row of my grid in the xaml:
我将以下语句放在 xaml 网格的第二行中：
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="1">
<ListView Name="listView" Margin="5" Grid.Row="1">
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn DisplayMemberBinding="{Binding Path=DateTime}" Header="Date Time" Width="140"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Vehicle}" Header="Vehicle" Width="130"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=AlarmType}" Header="Alarm Type" Width="100"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Direction}" Header="Direction" Width="100"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Speed}" Header="Speed" Width="100"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Alarmed}" Header="Alarmed" Width="100"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=LoadType}" Header="Load Type" Width="100"/>
<GridViewColumn DisplayMemberBinding="{Binding Path=Status}" Header="Status" Width="110"/>
</GridView>
</ListView.View>
</ListView>
</ScrollViewer>
</Grid>
I binded the listView.ItemSource to an ObservableCollection defined in the code to populate data to the list. When the number of items added to the GridView exceeded the listview height, the vertical scroll bar did not appear as i specified in the XAML. What did I do wrong? Your input is greatly appreciated. Thank you.
我将 listView.ItemSource 绑定到代码中定义的 ObservableCollection 以将数据填充到列表中。当添加到 GridView 的项目数超过列表视图高度时，垂直滚动条没有像我在 XAML 中指定的那样出现。我做错了什么？非常感谢您的意见。谢谢你。

It works for me:
这个对我有用：
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="1">
<ListView Name="listView" Margin="5" Grid.Row="1">
<ListView.View>
<GridView AllowsColumnReorder="True">
<GridViewColumn DisplayMemberBinding="{Binding Path=.}" Header="Whatever" Width="140"/>
</GridView>
</ListView.View>
</ListView>
</ScrollViewer>
</Grid>
</Window>
However, the ListViewcontrol template contains a ScrollVieweralready such that the ScrollViewerwill appear insidethe ListViewas and when needed. Why do you need to wrap it in another?
然而，ListView控制模板包含一个ScrollViewer已经使得ScrollViewer会出现内部的ListView作为并在需要时。为什么你需要把它包装在另一个？

See that the margins and paddings are correct. The scrollbar can be behind something.
查看边距和填充是否正确。滚动条可以在某物后面。
Put the exterior container height with a fixed value, It can be stretchingthe listview so it will never show the scrollbar.
将外部容器高度设置为固定值，它可以拉伸列表视图，因此它永远不会显示滚动条。

Try this code:
试试这个代码：
ListView listView = new ListView();
listView.SetValue(Grid.RowProperty, 1);
listView.SetValue(Grid.ColumnProperty, 1);
MainGrid.Children.Add(listView);
回答by Praveen Chandran
No need of using ScrollViewer. Just remove the ScrollViewerand use only the ListViewand try.
无需使用ScrollViewer. 只需删除ScrollViewer并仅使用ListView并尝试。
ListView listView = new ListView();
listView.SetValue(Grid.RowProperty, 1);
listView.SetValue(Grid.ColumnProperty, 1);
MainGrid.Children.Add(listView);
No need of specifying the width and height for the listview.
无需指定列表视图的宽度和高度。
