在一个StackPanel中我添加从code一些标签后面在运行时：我想作的StackPanel滚动。 XAML文件中我有：

in a stackpanel i add some labels from code behind at runtime: i want make the stackpanel scrollable. In the xaml file i have:

<ScrollViewer HorizontalAlignment="Left" Height="299" Margin="592,120,0,0" VerticalAlignment="Top" Width="188" VerticalScrollBarVisibility="Auto">

    <StackPanel x:Name="stackPanelVistaProfiloTessera" Height="292" Width="170"/>

</ScrollViewer>

在code后面我添加了一些标签的StackPanel的：

In the code behind i add some label to the stackpanel:

for(.....)
{
    stackPanelVistaProfiloTessera.Children.Add(new Label {....});
}

为什么StackPanel中不可滚动？我该如何解决？

Why the stackpanel isn't scrollable? How can i resolve this?

感谢

推荐答案

删除高度和宽度从stackpanel..rest正在这里很好。

Remove height and width from stackpanel..rest is working fine here.

<ScrollViewer HorizontalAlignment="Left" Background="Green" Height="299" Margin="592,120,0,0" VerticalAlignment="Top" Width="188" VerticalScrollBarVisibility="Auto">
    <StackPanel x:Name="stackPanelVistaProfiloTessera"  Background="RoyalBlue" >
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
        <Label Height="30" Width="100" Margin="5">label1</Label>
    </StackPanel>
</ScrollViewer>

输出这个样子的。

Output look like this.

，你可以设置保证金，如果您使用的是高度和宽度的设计目的的StackPanel。

and you can set margin to stackpanel if you are using height and width for design purpose.
