滚动查看器不适用于Windows Phone 8中的画布

时间：2014-01-11 12:44:02

标签： wpf xaml canvas scrollview

我有一个xaml文件，其中我用scroll viewer声明了canvas。

执行应用程序后，我只能看到10个画布（9个和一半），当我滚动到那里时，我可以看到所有9个半画布的移动，但屏幕上不再显示画布。 在第10幅画布（9.5）之后，我只看到黑色背景

canvas on scroll viewer

修改
如果我使滚动查看器的高度变短，它会变得可滚动，但只能滚动到9和半画布。

继承你的问题。 StackPanel的高度为607，所以只需删除

<StackPanel x:Name="ContentPanel" Height="607" Width="456">

由于设备尺寸不同，设置宽度不是很好，尝试使用具有灵活布局的网格。对于你的例子是这样的。注意VerticalAlignment和Horizo​​ntalAlignments在绘制布局时非常有用。

<ScrollViewer Grid.Row="1">           
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="65" />
                    <RowDefinition Height="65" />
                </Grid.RowDefinitions>
                <Grid x:Name="panel1">
                    <TextBlock x:Name="sub1" TextWrapping="Wrap" Text="My Heading 001" Foreground="White" FontSize="21.333"/>
                    <TextBlock x:Name="author1" TextWrapping="Wrap" Text="By-Gaurav Sharma" FontSize="13.333"
                               VerticalAlignment="Bottom" Margin="50,0,0,0"/>
                    <TextBlock x:Name="date1" HorizontalAlignment="Right" TextWrapping="Wrap" Text="02-Jul-2013"  FontSize="16"/>
                </Grid>
                <Grid x:Name="panel2" Grid.Row="1">
                    <TextBlock x:Name="sub2" TextWrapping="Wrap" Text="My Heading 002" Foreground="White" FontSize="21.333"/>
                    <TextBlock x:Name="author2"  TextWrapping="Wrap" Text="By-Gaurav Sharma" FontSize="13.333"
                               VerticalAlignment="Bottom" Margin="50,0,0,0"/>
                    <TextBlock x:Name="date2" HorizontalAlignment="Right" TextWrapping="Wrap" Text="02-Jul-2013"  FontSize="16"/>
                </Grid>
            </Grid>             
    </ScrollViewer> ... ...
