我一直在互联网上上下寻找，很多人似乎都有这个问题，但它通常通过将容器更改为网格、限制高度等来解决。我似乎无法让它工作。我有一个输入数据模板的 observableCollection。我一辈子都无法让滚动条正常工作。它在那里但没有启用。谢谢斯科特

一定是个bug。我只有以下..

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="ComfortReportEng.Views.EngineerReport.EngineerReport"
Title="Engineer Report" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded" SizeToContent="WidthAndHeight" >
<Window.Resources>
    <CollectionViewSource x:Key="cvsReportList"/>
</Window.Resources>
    <Grid Margin="0.125,0.412,3.125,0" Height="471">
        <ListBox Margin="23,64,3,0" Width="834.14"  ItemsSource="{Binding Source={StaticResource cvsReportList}}" 
            x:Name="lbReportList" SelectionChanged="lbReportList_SelectionChanged" Background="#FFEEEFE4" />
    </Grid>

和代码是

 private void LoadReportList()
    {
        int number = 0;
        List<int> myNumbers = new List<int>();
        while (number < 80)
        {
            myNumbers.Add(number);
            number += 1;
        }
        _cvsReportList = (CollectionViewSource)(this.FindResource("cvsReportList"));
        _cvsReportList.Source = myNumbers;
    }

这是从另一个项目复制过来的。完全糊涂了。请不要担心。这不是逻辑问题。请将此视为没有解决方案的近距离电话。再次干杯斯科特

只是为了给出这个完整性。我不确定为什么会发生这种情况，但就是这样。

if (System.Environment.MachineName == "SCOTT-PC")
        {
            this.txtUserName.Text = "Scott Fisher";
            this.txtPassword.Password = "palace";
            //LoginOK();

        }
        else
            Keyboard.Focus(this.txtUserName);

如果我清除对 LoginOK 过程的评论，我将没有滚动条。评论它并且我与登录屏幕交互然后一切都很好。最后是 LoginOK 的代码。if (LoginService.CheckLogin(txtUserName.Text, txtPassword.Password.ToString())) { Helpers.User.ThisUser = this.txtUserName.Text;

                EngineerReport.EngineerReport engReport = new EngineerReport.EngineerReport()
                {
                    Owner = Window.GetWindow(this),
                    WindowStartupLocation =
                        System.Windows.WindowStartupLocation.
                        CenterOwner
                };
                this.Hide();
                engReport.ShowDialog();
            }
            else
            {
                this.txtPassword.Password = "";
                this.txtPassword.Focus();
            }

您能否为您提供 DataTemplate，因为我相信我刚刚设法模拟了您要实现的目标，并且滚动条可见并且从一开始就可以工作。

这是我用于 ListBox 的 DataTemplate 的 xaml：

    <ListBox DataContext="{StaticResource MusicData}" ItemsSource="{Binding XPath=Album}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <ListBoxItem>
                    <StackPanel Orientation="Horizontal" >
                        <TextBlock>No.</TextBlock>
                        <TextBlock Text="{Binding XPath=No}"></TextBlock>
                        <TextBlock>Title</TextBlock>
                        <TextBlock Text="{Binding XPath=Title}"></TextBlock>
                    </StackPanel>
                </ListBoxItem>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

希望这可以帮助。

我还发现了一段我不久前使用过的代码，这可能会有所帮助。您可以尝试设置 ItemsPanelTemplate：

    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel>
                <ScrollViewer VerticalScrollBarVisibility="Visible" />
            </StackPanel>
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>

这将适用于本文所述的任何项目控件：http: //msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.itemcontainerstyle.aspx

我可以建议的最后一件事是为 ListBox 创建自己的 ControlTemplate，如下所示：

<ListBox.Template>
    <ControlTemplate>
        <ScrollViewer VerticalScrollBarVisibility="Auto">
            <ItemsPresenter />
        </ScrollViewer>
    </ControlTemplate>
</ListBox.Template>
