将滚动条添加到ItemsControl [英] Add scrollbar to ItemsControl

问题描述

我在ItemsControl中添加了一个滚动条，但它仍然是不可见的。

I added a scroll bar to the ItemsControl, but it is still invisible.

<DockPanel>
        <ScrollViewer VerticalScrollBarVisibility="Auto">
        <ItemsControl Height="300" Name="icTodoList">
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="*"/>
                            <RowDefinition Height="*"/>
                            <RowDefinition Height="*"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <TextBlock Text="{Binding StartTime, FallbackValue=' '}" Grid.Row="0"/>
                        <TextBlock Text="{Binding ConnectedTime, FallbackValue=' '}" Grid.Row="1"/>
                        <TextBlock Text="{Binding DisconnectedTime, FallbackValue=' '}" Grid.Row="2"/>
                        <TextBlock Text="{Binding DialResult, FallbackValue=' '}" Grid.Row="3"/>
                    </Grid>
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
        </ScrollViewer>
    </DockPanel>

推荐答案

最后我找到了解决方案。我必须将高度添加到DockPanel。

Finally I found the solution. I have to add Height to DockPanel.

<dockpanel Height="280"></dockpanel>

Richard的解决方案，即尝试删除高度=300来自 ItemsControl 的属性不起作用。

Richard's solution, which was to try removing the Height="300" attribute from the ItemsControl doesn't work.
