滚动查看器SIP问题(WP7.5芒果) [英] Scrollviewer & SIP Issue (WP7.5 Mango)

问题描述

我正在处理包含注册表的应用程序.该表单包含多个文本输入框，因此使用ScrollViewer允许它们全部显示在一页上.

I am working on an application which includes a registration form. The form contains multiple text entry boxes, and so a ScrollViewer is used to allow them all to be displayed on one page.

以下是我正在使用的XAML代码的精简示例:

The following is a stripped down example of the XAML code I am using:

<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

    <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
        <TextBlock x:Name="ApplicationTitle" Text="SCROLLVIEWER TEST" Style="{StaticResource PhoneTextNormalStyle}"/>
        <TextBlock x:Name="PageTitle" Text="registration" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
    </StackPanel>

    <ScrollViewer Grid.Row="1">
        <StackPanel>
            <TextBlock Text="Hello" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello1" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello2" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello3" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello4" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello5" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello6" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello7" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="Hello8" Margin="12,0,0,0"/>
            <TextBox />
            <TextBlock Text="END" Margin="12,0,0,0"/>
            <TextBox />
        </StackPanel>
    </ScrollViewer>
</Grid>

(请注意，ScrollViewer在网格单元内，这意味着标题面板应始终保持在屏幕上)

(Note that the ScrollViewer is inside a grid cell, which means that the title panel should stay OnScreen at all times)

滚动效果很好，所以这不是问题.但是，当用户选择文本框输入数据时(即，软键盘打开)，系统会将整个页面的内容(包括注册标题面板)推送到周围，这是不希望的行为. [请参阅Windows Phone上的人脉"应用，然后尝试添加新联系人.它包含类似的结构，但ScrollViewer的行为仅通过向上滚动scrollviewer中的内容才能正确执行.]

The scrolling works perfectly fine, so that is not an issue. However, when the user selects a TextBox to enter data (i.e. the soft keyboard opens), the system pushes the content of the entire page around (including the registration title panel), which is not expected behaviour. [See the People app on Windows Phone and try adding a new contact. This contains a similar structure, but the ScrollViewer behaves correctly by only pushing content in the scrollviewer up]

测试用例

• 选择一个在屏幕顶部附近可见的文本框，以打开键盘.
• 尝试在键盘打开的情况下滚动到页面底部.
• 页面底部的项目无法访问.

或

• 选择一个在屏幕底部附近可见的文本框.
• 整个页面的内容被上推.
• 尝试在键盘打开的情况下滚动到页面顶部.
• 页面顶部的项目无法访问，并且在关闭键盘之前，标题面板永远不会回到视图中.

对于解决此问题的任何帮助，将不胜感激.谢谢.

Any help on resolving this issue would be appreciated. Thanks.
