想使ScrollViewer包含StackPanel该怎么写？

Question

    <Grid x:Name="LayoutRoot" Background="White">
     <ScrollViewer Width="178" Background="Black" HorizontalAlignment="Left">
      <StackPanel x:Name="b"></StackPanel>
     </ScrollViewer>
    </Grid>

改成后台怎么写？

也就是说：

ScrollViewer a = new ScrollViewer();
StackPanel b = new StackPanel();
我要使b是a的Children 该怎么写？

Answer 1

你好，

你可以试一下以下代码：

            ScrollViewer sv = new ScrollViewer();
            StackPanel sp = new StackPanel();
            
            for (int i = 1; i < 200; i++)
            {
                TextBox tb = new TextBox();
                tb.Name="textbox"+i.ToString();
                tb.Text = tb.Name;
                sp.Children.Add(tb);
            }
            //TextBox tb = new TextBox();

            //sp.Children.Add(tb);
            sv.Content = sp;

            LayoutRoot.Children.Add(sv);   

结果：
