Question

我是这个论坛的新手，也是Windows Phone 8开发的新手。

我有以下代码

<Grid x:Name="LayoutRoot" Background="#EEF8E5" Loaded="LayoutRoot_Loaded">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <!--TitlePanel contains the name of the application and page title-->
        <TextBlock x:Name="ApplicationTitle" FontWeight="Bold" Padding="20,0,0,0" Grid.Row="0" Text="فرآن کریم"/>

        <ScrollViewer  Grid.Row="1" VerticalScrollBarVisibility="Visible"
                      x:Name="Scroller"  VerticalContentAlignment="Top" >
            <Grid x:Name="ContentPanel" Margin="20,0,0,0">
                <Grid.RowDefinitions>
                    <RowDefinition Height="70"></RowDefinition>
                    <RowDefinition Height="*"></RowDefinition>
                </Grid.RowDefinitions>
                <TextBlock x:Name="txtBismullah" FontSize="40" HorizontalAlignment="Center" Grid.Row="0"></TextBlock>
                <TextBlock x:Name="txt" FontSize="40" Grid.Row="1" TextWrapping="Wrap" />
            </Grid>
        </ScrollViewer>

        <Grid Grid.Row="2" Background="Silver" VerticalAlignment="Bottom">
            <Button Content="1" Width="100" BorderThickness="0" VerticalAlignment="Top" Click="Button_Click"></Button>
        </Grid>
    </Grid>

和c＃

string readData()
        {
            string suraIndex = string.Empty;
            int counter = 1;
            for (int i = 0; i < 40; i++)
                suraIndex += counter++ + Environment.NewLine;
            return suraIndex;

        }

最后

txt.Text += readData();
txt.Text += " I am Here";

问题是，它没有显示所有文本，它只显示最多35（因为滚动条有滚动）但没有显示文本。

我不知道文本块有什么问题，或者可能是它的高度，尽管它被设置为自动。

Answer 1

您应该将TextBlock放在ScrollViewer而不是整个Grid

<Grid Grid.Row="1" x:Name="ContentPanel" Margin="20,0,0,0">
  <Grid.RowDefinitions>
    <RowDefinition Height="70"/>
    <RowDefinition Height="*"/>
  </Grid.RowDefinitions>
  <TextBlock x:Name="txtBismullah" FontSize="40" HorizontalAlignment="Center" Grid.Row="0"/>
  <ScrollViewer x:Name="Scroller" Grid.Row="1" VerticalScrollBarVisibility="Visible" VerticalContentAlignment="Top" >
    <TextBlock x:Name="txt" FontSize="40" Grid.Row="1" TextWrapping="Wrap" />
  </ScrollViewer>
</Grid>

Answer 2

使用列表框而不是文本块对其进行排序。

TextBlock不显示所有文本
