项目组内的垂直滚动

项目组内的垂直滚动

本文介绍了WinRT XAML 中 GridView 项目组内的垂直滚动的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我使用 GridView 在 WinRT XAML 应用程序中显示不同组的项目.一切都很好,除了 ItemsPanelTemplate 使用了一个环绕网格,当我的项目空间不足时,它会垂直堆叠我的项目.

I am using GridView for displaying groups of different sets of items in a WinRT XAML app. Everything works well, except that the ItemsPanelTemplate uses a wrapping grid which stacks my items vertically when it's out of space.

所以,我尝试使用 StackPanel,如下所示:

So, I tried to use StackPanel, like this:

<GroupStyle.Panel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Vertical" Visibility="Visible" />
    </ItemsPanelTemplate>
</GroupStyle.Panel>

这些项目是垂直堆叠的,这很好,但现在的问题是我无法滚动它们,而且它们不适合屏幕.所以我尝试启用垂直滚动:

The items are stacked vertically, and that's great, but the problem is now that I can't scroll them, and they don't fit on the screen. So I tried enabling vertical scrolling:

<GroupStyle.Panel>
    <ItemsPanelTemplate>
        <StackPanel Orientation="Vertical" Visibility="Visible"
                    ScrollViewer.VerticalScrollBarVisibility="Visible"
                    ScrollViewer.VerticalScrollMode="Enabled"/>
    </ItemsPanelTemplate>
</GroupStyle.Panel>

但这行不通.有什么建议如何在 GridView 组内完成垂直滚动?

But that doesn't work.Any suggestions how to accomplish vertical scrolling inside GridView group?

编辑 1:

我也试过这个:

<GroupStyle.Panel>
    <ItemsPanelTemplate>
        <ScrollViewer VerticalScrollBarVisibility="Visible"
                      HorizontalScrollMode="Disabled"
                      ZoomMode="Disabled"
                      VerticalScrollMode="Enabled">
              <StackPanel Orientation="Vertical" Visibility="Visible" />
         </ScrollViewer>
     </ItemsPanelTemplate>
 </GroupStyle.Panel>

这会破坏调试器,因为 ItemsPanelTemplate 需要一个面板作为子项.

This breaks the debugger as the ItemsPanelTemplate needs a panel as a child.

推荐答案

好的,我终于解决了!可能涉及的对象:

OK, I finally solved it! To whom it may concern:

<GroupStyle.ContainerStyle>
    <Style TargetType="GroupItem">
        <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="GroupItem">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="Auto"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>
                    <ContentPresenter Content="{TemplateBinding Content}" Grid.Row="0"/>
                    <ItemsControl x:Name="ItemsControl2" ItemsSource="{Binding GroupItems}" Grid.Row="1">
                        <ItemsControl.Template>
                        <ControlTemplate>
                            <ScrollViewer x:Name="ScrollViewer" VerticalScrollBarVisibility="Hidden"                                                  VerticalScrollMode="Enabled" HorizontalScrollBarVisibility="Disabled"                                                  HorizontalScrollMode="Disabled">
                            <ItemsPresenter />
                            </ScrollViewer>
                        </ControlTemplate>
                        </ItemsControl.Template>
                    </ItemsControl>
                </Grid>
           </ControlTemplate>
       </Setter.Value>
       </Setter>
   </Style>
</GroupStyle.ContainerStyle>

使用网格来确保 ScrollViewer 正确缩放很重要.

It's important that you use the Grid to make sure that the ScrollViewer scales correctly.
