流体列表框上的水平滚动条
我想要什么:让该死的水平滚动条出现。我将对其进行一些编辑,以便适合应用程序的其余样式方案,但不会太多。
我拥有的
这是目前列表框的代码。除了滚动条不出现之外,一切都运行完美。你可能会说......“好吧,你在任何地方都没有滚动查看器”,但我已经尝试在很多地方插入滚动查看器,但仍然没有运气。
列表框代码:
<ListBox ItemsSource="{Binding Items}" ItemTemplate="{StaticResource itemsdatatemplate}" Background="{x:Null}" BorderBrush="{x:Null}" Foreground="{x:Null}" ItemsPanel="{StaticResource HorizontalListBoxTemplate}" ItemContainerStyle="{StaticResource TransparentListBox}" VerticalAlignment="Center" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" />
'TransparentListBox'(关闭选定的背景颜色):
<Style x:Key="TransparentListBox" TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid>
<Border x:Name="HoverBorderBackgroundBrush" BorderThickness="1" Margin="0,0,25,0" Background="Transparent"/>
<Border x:Name="SelectedBorderBackgroundBrush" BorderThickness="1" Margin="0,0,25,0" Background="Transparent"/>
<ContentPresenter></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
水平列表框(使列表框水平,而不是标准垂直)
<ItemsPanelTemplate x:Key="HorizontalListBoxTemplate">
<StackPanel Orientation="Horizontal">
</StackPanel>
</ItemsPanelTemplate>
数据模板(实际显示项目)
<DataTemplate x:Key="itemsdatatemplate">
<local:ListItemControl HorizontalAlignment="Left" VerticalAlignment="Top" DataContext="{Binding}"/>
</DataTemplate>
我有一种感觉,这将是一个简单的添加,但提前致谢。
更新
看起来滚动条现在确实出现了:
<Style x:Key="ScrollingListBox" TargetType="ListBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid>
<ScrollViewer HorizontalScrollBarVisibility="Visible">
<ItemsPresenter></ItemsPresenter>
</ScrollViewer>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
但它们没有相应的功能。他们感觉……破碎了。但是,如果要定义网格的静态宽度(例如 300),则 ScrollViewer 的效果非常好。现在我有一个完全流畅的布局(意味着东西会拉伸以填充),这对于滚动查看器来说是不可接受的吗?
What I want: To get the darn horizontal scrollbar to appear. I will be editing it a bit just so i fits the rest of the app's style scheme, but not too much.
What I have
Here is the code for the listbox as of now. Everything runs perfectly except the scrollbars dont appear. You might say... "well you dont have a scrollviewer anywhere", but I have tried inserting a scrollviewer in numerous places and still no luck.
The Listbox Code:
<ListBox ItemsSource="{Binding Items}" ItemTemplate="{StaticResource itemsdatatemplate}" Background="{x:Null}" BorderBrush="{x:Null}" Foreground="{x:Null}" ItemsPanel="{StaticResource HorizontalListBoxTemplate}" ItemContainerStyle="{StaticResource TransparentListBox}" VerticalAlignment="Center" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" />
The 'TransparentListBox' (to shut-up the selected background color):
<Style x:Key="TransparentListBox" TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid>
<Border x:Name="HoverBorderBackgroundBrush" BorderThickness="1" Margin="0,0,25,0" Background="Transparent"/>
<Border x:Name="SelectedBorderBackgroundBrush" BorderThickness="1" Margin="0,0,25,0" Background="Transparent"/>
<ContentPresenter></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Horizontal List Box (to make the listbox Horizontal, rather than standard vertical)
<ItemsPanelTemplate x:Key="HorizontalListBoxTemplate">
<StackPanel Orientation="Horizontal">
</StackPanel>
</ItemsPanelTemplate>
The Datatemplate (to actually show the Items)
<DataTemplate x:Key="itemsdatatemplate">
<local:ListItemControl HorizontalAlignment="Left" VerticalAlignment="Top" DataContext="{Binding}"/>
</DataTemplate>
I have a feeling its going to be a simple addition, but Thanks in advance.
Update
It looks like the scrollbars now do appear with this:
<Style x:Key="ScrollingListBox" TargetType="ListBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid>
<ScrollViewer HorizontalScrollBarVisibility="Visible">
<ItemsPresenter></ItemsPresenter>
</ScrollViewer>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But they do not function accordingly. They feel... broken. However, if one was to define a static width (say 300) of the grid, then the ScrollViewer acts perfectly. Right now I have a completely fluid layout (meaning things stretch to fill), is this not acceptable for scrollviewers?

当您创建自己的模板时,您必须在其中定义 ScrollViewer 并使用 ItemPresenter 而不是 ContentPresenter。
When you create your own template, you have to define the ScrollViewer in there and use an ItemPresenter instead of a ContentPresenter.
