c# - 将 ScrollViewer（通过 c# 代码）添加到 TabPage

Question

我正在尝试将 a 添加System.Windows.Controls.ScrollViewer到 a System.Windows.Forms.TabPage，但是该函数Add(ScrollViewer)无效。

有没有办法将 ScrollViewer 添加到TabPage内置的而不是 XAML 中。

谢谢。

由于您已将此标记为 WPF，我猜对 Forms 的引用可能是错误的？

这是选项卡中的页面示例 - 其想法是确保工具栏保持在顶部，状态栏保持在底部（不是 MainWindow 状态栏......）并且中间的内容可以滚动。 .

Dim vScrollViewer As New ScrollViewer
        Dim vSP As New StackPanel
        With vSP
            .HorizontalAlignment = Windows.HorizontalAlignment.Stretch
            .VerticalAlignment = Windows.VerticalAlignment.Stretch
        End With
        Dim vInnerGrid As New Grid
        vScrollViewer.Content = vSP
        vSP.Children.Add(vInnerGrid)

vScollViewer 可以添加到任何其他控件（例如三行网格的中间）
