WPF C＃在包裝面板中尋呼

Question

我從數據庫填充了一些文本（我將它們命名爲問題），但在我的包裝面板中，我只能顯示3個問題，剩下的問題被截斷，我有3個以上問題，我如何在包裝面板中進行分頁以在面板本身上顯示問題的其餘部分？我填充的問題for循環是這樣的：

for(int i= 0 ; i<lstQuestion.Count()-2; i++) 
     { 
      TextBlock tb = new TextBlock(); // Question 
      tb.FontSize = 19; 
      tb.FontWeight = FontWeights.Bold; 
      tb.Text = lstQuestion[i].QuestionContent; 
      tb.TextWrapping = TextWrapping.Wrap; 
      wrapPanel1.Children.Add(tb); 



      TextBox tbox = new TextBox(); 
      if (lstQuestion[i].Answer.Trim().Length > 0) // Textbox for user to input answer in every question 
      { 

       tbox.FontSize = 19; 
       tbox.Width = 250; 
       tbox.Height = 50; 
       tbox.PreviewDrop += new DragEventHandler(tbox_PreviewDrop); 
       tbox.Focusable = false; // Disallow user to input anything into it. 
       wrapPanel1.Children.Add(tbox); 
      } 

      answers.Add(lstQuestion[i].Answer); 

      if (lstQuestion[i].QuestionNo != lstQuestion[i + 1].QuestionNo) // add spacing between question 
      { 
       StackPanel sp = new StackPanel(); 
       sp.Width = 1010; 
       wrapPanel1.Children.Add(sp); 
       Label spacing = new Label(); 
       spacing.Width = 1010; 
       spacing.Content = ""; 
       wrapPanel1.Children.Add(spacing); 
      } 

     } // end of for each loop. 

在我的XAML：

<Grid> 
    <WrapPanel HorizontalAlignment="Center" Name="wrapPanel1" VerticalAlignment="Center" Height="400" Width="1038" Margin="0,77,0,43" /> 
    <WrapPanel Height="80" HorizontalAlignment="Center" Name="wrapPanel2" VerticalAlignment="Top" Background="Aquamarine" Width="1000"> 
    </WrapPanel> 
    <Button Content="Check" Height="37" HorizontalAlignment="Center" Name="button1" VerticalAlignment="Bottom" Width="90" FontSize="24" Margin="474,0" Click="button1_Click" /> 

</Grid> 

Wrappanel1是我把我的問題，並在文本框（畫布面板1是我想做的面板分頁），wrappanel2是另一個可以選擇答案的面板。

你可以從灰色箭頭看到，還有更多的文字，但它只是在滾動結束停在那裏。

把你的wrapPanel1放在ScrollViewer裏面。

<ScrollViewer VerticalAlignment="Center" HorizontalAlignment="Center" Height="400" Width="1038"> 
    <WrapPanel Name="wrapPanel1" /> 
</ScrollViewer> 

嘗試用RowDefinitions

<Grid> 
    <Grid.RowDefinitions> 
     <RowDefinition Height="80"></RowDefinition> 
     <RowDefinition Height="Auto"></RowDefinition> 
     <RowDefinition Height="40"></RowDefinition> 
    </Grid.RowDefinitions> 

    <WrapPanel Grid.Row="0" HorizontalAlignment="Center" Name="wrapPanel2" Background="Aquamarine" Width="1000"></WrapPanel> 

    <ScrollViewer Grid.Row="1" Height="400" Width="1038" CanContentScroll="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"> 
     <WrapPanel Name="wrapPanel1"/> 
    </ScrollViewer> 

    <Button Grid.Row="2" Content="Check" Margin="5" HorizontalAlignment="Center" Name="button1" VerticalAlignment="Bottom" Width="90" FontSize="24" Click="button1_Click" /> 
</Grid>
