我尝试创建一个可滚动的水平StackPanel,但我没有成功......
目前我的StackPanel宽度为auto
(问题可能在这里),其中包含grids
等一些项目。
现在,如果我的所有网格在StackPanel中都不可见(宽度太短)我无法滚动。
我已经尝试将StackPanel放在ScrollViewer
内,但它没有
也工作。
我该如何解决这个问题?
编辑这是我的代码:
<StackPanel Height="85" Margin="0,0,200,15" VerticalAlignment="Bottom">
<ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled" HorizontalAlignment="Left" Height="85" CanContentScroll="True">
<StackPanel x:Name="Film" Height="85" Width="Auto" Margin="0,0,0,0" Orientation="Horizontal" ScrollViewer.HorizontalScrollBarVisibility="Visible" CanHorizontallyScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.CanContentScroll="True" d:LayoutOverrides="TopPosition, BottomPosition">
<StackPanel.Background>
<SolidColorBrush Color="{DynamicResource ButtonBackground}"/>
</StackPanel.Background>
<Grid Width="100" Background="Red"/>
<Grid Width="100" Background="#FFFF0051"/>
<Grid Width="100" Background="#FFB900FF"/>
<Grid Width="100" Background="#FF002EFF"/>
<Grid Width="100" Background="#FF00FFDC"/>
<Grid Width="100" Background="#FF51FF00"/>
<Grid Width="100" Background="Red"/>
</StackPanel>
</ScrollViewer>
</StackPanel>

目前我的stackpanel有一个自动宽度(问题可能就在这里),其中包含一些像栅格这样的项目。
这 你的问题。如果StackPanel的Orientation属性设置为Horizontal而无限的垂直空间(如果设置为Vertical),则StackPanel将测量其子级具有无限水平空间。因此,您必须为StackPanel本身或ScrollViewer指定显式宽度才能使其工作。
或者,您可以将ScrollViewer放在一个测量其子节点的Panel中,例如Grid(但不是StackPanel)。这适用于例如:
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="Window" Height="300" Width="300">
<Grid>
<ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled" HorizontalAlignment="Left" Height="85" CanContentScroll="True">
<StackPanel x:Name="Film" Height="85" Width="Auto" Margin="0,0,0,0" Orientation="Horizontal" ScrollViewer.HorizontalScrollBarVisibility="Visible" CanHorizontallyScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.CanContentScroll="True" d:LayoutOverrides="TopPosition, BottomPosition">
<StackPanel.Background>
<SolidColorBrush Color="Yellow"/>
</StackPanel.Background>
<Grid Width="100" Background="Red"/>
<Grid Width="100" Background="#FFFF0051"/>
<Grid Width="100" Background="#FFB900FF"/>
<Grid Width="100" Background="#FF002EFF"/>
<Grid Width="100" Background="#FF00FFDC"/>
<Grid Width="100" Background="#FF51FF00"/>
<Grid Width="100" Background="Red"/>
</StackPanel>
</ScrollViewer>
</Grid>
</Window>
但这不是因为StackPanel被认为具有无限宽度:
<StackPanel>
<ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Disabled" HorizontalAlignment="Left" Height="85" CanContentScroll="True">
<StackPanel x:Name="Film" Height="85" Width="Auto" Margin="0,0,0,0" Orientation="Horizontal" ScrollViewer.HorizontalScrollBarVisibility="Visible" CanHorizontallyScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.CanContentScroll="True" d:LayoutOverrides="TopPosition, BottomPosition">
<StackPanel.Background>
<SolidColorBrush Color="Yellow"/>
</StackPanel.Background>
<Grid Width="100" Background="Red"/>
<Grid Width="100" Background="#FFFF0051"/>
<Grid Width="100" Background="#FFB900FF"/>
<Grid Width="100" Background="#FF002EFF"/>
<Grid Width="100" Background="#FF00FFDC"/>
<Grid Width="100" Background="#FF51FF00"/>
<Grid Width="100" Background="Red"/>
</StackPanel>
</ScrollViewer>
</StackPanel>
将ScrollViewers放在StackPanels中是个坏主意。

您应该将StackPanel放入ScrollViewer中,如下所示:
<ScrollViewer Height="85" VerticalAlignment="Bottom" Margin="0,0,200,15" VerticalScrollBarVisibility="Disabled" HorizontalScrollBarVisibility="Auto">
<StackPanel x:Name="Film" Orientation="Horizontal" >
<StackPanel.Background>
<SolidColorBrush Color="Black"/>
</StackPanel.Background>
<Grid Width="100" Background="Red"/>
<Grid Width="100" Background="#FFFF0051"/>
<Grid Width="100" Background="#FFB900FF"/>
<Grid Width="100" Background="#FF002EFF"/>
<Grid Width="100" Background="#FF00FFDC"/>
<Grid Width="100" Background="#FF51FF00"/>
<Grid Width="100" Background="Red"/>
</StackPanel>
</ScrollViewer>
