我有一个显示WPF控件列表的ListBox
,但问题是即使有足够的项目应该需要滚动ListBox
时,垂直滚动条也显示为禁用状态。另一个可能相关的事实是这个ListBox
包含在一个Integration.ElementHost
中。
以下是ListBox
的XAML代码:
// for brevity I removed the Margin and Tooltip attributes
<Grid x:Class="Xyzzy.NoteListDisplay"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel Name="stackPanel" Orientation="Vertical"
ScrollViewer.VerticalScrollBarVisibility="Visible">
<StackPanel Orientation="Horizontal">
<CheckBox Name="AllRecent" IsChecked="False" >View All Recent</CheckBox>
<CheckBox Name="AscendingOrder" IsChecked="False">Descending Order</CheckBox>
<Button Name="btnTextCopy" Click="btnCopyText_Click">Copy All</Button>
</StackPanel>
<ListBox Name="NoteList"
ScrollViewer.CanContentScroll="True"
ScrollViewer.VerticalScrollBarVisibility="Visible">
</ListBox>
</StackPanel>
</Grid>
每个 ListBox
项显示的控件的 XAML:
<UserControl x:Class="Xyzzy.NoteDisplay"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBlock Name="Heading" FontSize="10">Note Heading</TextBlock>
<Button Name="btnCopyText" Height="20" FontSize="12"
Click="btnCopyText_Click">Copy
</Button>
</StackPanel>
<TextBlock Name="Body" FontSize="14">Note Body</TextBlock>
</StackPanel>
</Grid>
</UserControl>
<RowDefinition Height="*" />
