Windows Phone文本框几乎无法点击

Question

我的Windows Phone应用程序中有一个TextBox。似乎只有文本框的上半部分可以点击来编辑文本。我需要整个文本框都是可点击的。

为什么会这样？

<Grid x:Name="FolderNameGrid">
    <TextBlock Text="{Binding SelectedPostbox.LabelToUpper}"
               Style="{StaticResource PageTitleTextBlockStyle}"
               Visibility="{Binding IsInSearchMode, Converter={StaticResource BoolToVisibilityConverter}, ConverterParameter=!}" />
    <TextBox x:Name="SearchTextBox"
             Margin="20,10,20,10"
             KeyDown="SearchTextBox_OnKeyDown"
             TextChanged="SearchTextBox_OnTextChanged"
             GotFocus="SearchTextBox_GotFocus"
             PlaceholderText="{Binding TextSource, Converter={StaticResource Language}, ConverterParameter=Module-Messages-Search, FallbackValue=Module-Messages-Search}"
             Visibility="{Binding IsInSearchMode, Converter={StaticResource BoolToVisibilityConverter}}" />
</Grid>

尝试将RowDefinitions添加到网格中。两个控件现在重叠。

例如

<Grid x:Name="FolderNameGrid">
    <Grid.RowDefinitions>
       <RowDefinition />
       <RowDefinition />
    </Grid.RowDefinitions>
    <TextBlock Text="{Binding SelectedPostbox.LabelToUpper}"
               Style="{StaticResource PageTitleTextBlockStyle}"
               Visibility="{Binding IsInSearchMode, Converter={StaticResource BoolToVisibilityConverter}, ConverterParameter=!}" />
    <TextBox Grid.Row="1"
             x:Name="SearchTextBox"
             Margin="20,10,20,10"
             KeyDown="SearchTextBox_OnKeyDown"
             TextChanged="SearchTextBox_OnTextChanged"
             GotFocus="SearchTextBox_GotFocus"
             PlaceholderText="{Binding TextSource, Converter={StaticResource Language}, ConverterParameter=Module-Messages-Search, FallbackValue=Module-Messages-Search}"
             Visibility="{Binding IsInSearchMode, Converter={StaticResource BoolToVisibilityConverter}}" />
</Grid>
