如何在 Silverlight 中将 ScrollBar 添加到 StackPanel? [英] How to add a ScrollBar to a StackPanel in Silverlight?

问题描述

我有一个 Grid，3 x 3(3 个 RowDefinitions 和 3 ColumnDefinitions).我想要滚动这些网格单元格之一中的一些内容(StackPanel).我相当确定这是可能的，但我无法弄清楚如何.我尝试将 ScrollViewers 和 ScrollBar 控件添加到我想要滚动的网格单元中，但这通常最终会为整个页面创建滚动.

I have a Grid, 3 by 3 (3 RowDefinitions and 3 ColumnDefinitions). I want some content (a StackPanel) in one of those grid cells to scroll. I'm fairly sure this is possible but I cannot figure out how. I've tried adding ScrollViewers and ScrollBar controls to the grid cell I want to scroll, but this usually ends up creating scrolling for the entire page.

我的问题更具体地说是如何滚动 StackPanel.一个例子，如果我遇到的问题在这里:

My issue is more specificlly how I can get scrolling over a StackPanel. An example if the issue I am having is here:

<Grid x:Name="LayoutRoot">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>

    <Grid>
        <TextBlock FontSize="16">1,1</TextBlock>
    </Grid>
    <Grid Grid.Column="1">
        <TextBlock FontSize="16">1,2</TextBlock>
    </Grid>
    <Grid Grid.Row="1">
        <TextBlock FontSize="16">2,1</TextBlock>
    </Grid>
    <Grid Grid.Column="1" Grid.Row="1">
        <StackPanel>
            <TextBlock>Title</TextBlock>
            <Grid>
                <ScrollViewer>
                    <StackPanel>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                        <TextBlock FontSize="32">2,2</TextBlock>
                    </StackPanel>
                </ScrollViewer>
            </Grid>
        </StackPanel>
    </Grid>
</Grid>

推荐答案

StackPanel 对待其内容具有无限的空间.要滚动堆栈面板，您将不得不对某些东西施加高度约束 - 最有可能是堆栈面板的网格父级.

StackPanel treats its content has having infinite space. To scroll the stackpanel, you're going to have to put a height constraint on something - the grid parent of the stackpanel, most likely.
