当屏幕高度减小时,如何在 XAML (UWP) 中垂直滚动整个页面?

How to Scroll whole page vertically in XAML (UWP) when screen height getting decrease?

我正在开发 Windows 通用平台应用程序。 我有关于屏幕的查询 height.I 使用视觉状态来管理屏幕宽度,因此应用程序可以响应,但是当屏幕高度降低时页面内容被剪切并且不正确 display.So 我只是检查了 windows 应用程序并了解了滚动查看器,但我不知道我在哪里放置滚动查看器,因此该应用程序将正确地 work.I 使用 MasterDetail 布局。

我附上了我的应用程序的屏幕截图,以便您正确理解问题,我还附上了代码。

代码:是示例代码,不是完整代码。

<Grid Background="White" x:Name="maingrid">
    <VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="PageSizeStatesGroup"
                          CurrentStateChanged="OnCurrentStateChanged">
            <VisualState x:Name="MediumState">
                <VisualState.StateTriggers>
                    <AdaptiveTrigger MinWindowWidth="720"  />
                </VisualState.StateTriggers>
                <VisualState.Setters>
                    <Setter Target="MasterColumn.Width" Value="350" />
                    <Setter Target="DetailColumn.Width" Value="*"/>
                </VisualState.Setters>
            </VisualState>
            <VisualState x:Name="WideState">
                <VisualState.StateTriggers>
                    <AdaptiveTrigger MinWindowWidth="1024"  />
                </VisualState.StateTriggers>
                <VisualState.Setters>
                    <Setter Target="MasterColumn.Width" Value="600" />
                    <Setter Target="DetailColumn.Width" Value="*"/>
                </VisualState.Setters>
            </VisualState>
            <VisualState x:Name="MobileState">
                <VisualState.StateTriggers>
                    <AdaptiveTrigger MinWindowWidth="320"  />
                </VisualState.StateTriggers>
                <VisualState.Setters>
                    <Setter Target="MasterColumn.Width" Value="0"/>
                    <Setter Target="DetailColumn.Width" Value="*"/>
                </VisualState.Setters>
            </VisualState>
        </VisualStateGroup>
     </VisualStateManager.VisualStateGroups>

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="auto" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition x:Name="MasterColumn" Width="600" />
            <ColumnDefinition x:Name="DetailColumn"  Width="*" />
        </Grid.ColumnDefinitions>

        <StackPanel x:Name="titlePanel" Grid.Row="0" Grid.Column="0">
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="auto"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>

                <Image x:Name="img_head" Grid.Column="0"  Stretch="Fill" Height="47" Margin="0,0,10,0"/>

                <StackPanel x:Name="Logo_txt_pnl" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Left">
                    <TextBlock x:Name="Customer_title" .... VerticalAlignment="Center"  HorizontalAlignment="Center"/>
                </StackPanel>

                <Image Grid.Row="0"  x:Name="line_dashboard" Grid.ColumnSpan="2"   VerticalAlignment="Bottom" Height="8" />
            </Grid>
        </StackPanel>

        <StackPanel Name="life_time_pnl" Grid.Row="1" Grid.Column="0">
            <!--Code for the grid and all-->
        </StackPanel>

        <StackPanel x:Name="sales_report_pnl" Grid.Row="0" Grid.Column="1" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
            <!--coding here-->
        </StackPanel>

        <StackPanel x:Name="stackReport"  Grid.Row="1" Grid.Column="1" VerticalAlignment="Top" >
            <!--Report Coding here-->
        </StackPanel>

        <StackPanel x:Name="stackLineChart" Grid.Row="1" Grid.Column="1" VerticalAlignment="Center" Margin="50,0,20,50"  HorizontalAlignment="Stretch">
            <!--Chart coding-->
        </StackPanel>

        <StackPanel x:Name="chartReportpnl" Orientation="Vertical" Grid.Row="1" Grid.Column="1"  VerticalAlignment="Bottom" Margin="0,0,0,2">
            <!--Report as all-->
        </StackPanel>

    </Grid>
</Grid>

所以建议我如何定义滚动查看器,以便应用程序根据高度进行响应。

只要把你所有的元素放到ScrollView控件中,它会自动改变,所以当你的页面足够大时,侧面没有滚动条,当它变小时,它会自动打开。

示例:

<ScrollView Grid.Row="1" Grid.Column="0" >
   <StackPanel Name="life_time_pnl">
      <!--Code for the grid and all-->
   </StackPanel>
</ScrollView>

<ScrollView Grid.Row="0" Grid.Column="1">
   <StackPanel x:Name="sales_report_pnl" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
      <!--coding here-->
   </StackPanel>
</ScrollView>

将整个网格放在一个相关面板中,并将相关面板放在滚动视图中,这样您就可以滚动整个页面。

<ScrollViewer>
    <RelativePanel>
        <Grid>

           //Your Page Code

        </Grid>
    </RelativePanel>
</ScrollViewer>

此外,如果您想要一个始终位于顶部的命令栏,那么您可以执行以下操作:

<Grid>
        <CommandBar>
           
         //Your Command Bar Code
  
        </CommandBar>
        <ScrollViewer>
            <RelativePanel>
                <Grid>
                     
                 //Scrollable Page Code

                </Grid>
            </RelativePanel>
        </ScrollViewer>
</Grid>
