當我需要通過代碼滾動到 GroupBox 控制元件的位置時，我正在開發一個小型應用程式，我的 xaml 檔案中包含滾動查看器的部分如下（我有一個滾動查看器，位于堆疊面板內和 GroupBox 內部):

我在stackoverflow中嘗試了其他解決方案，但我不知道為什么我不能處理它來作業。
我只有函式的宣告
private void ScrollToGroupBox(System.Windows.Controls.GroupBox groupBox)
{
//I NEED TO GET THE POSITION OF THE GRUOPBOX INSIDE OF THE SCROLLVIEWER
scrollViewer.ScrollToVerticalOffset(0);
}
uj5u.com熱心網友回復：
private void ScrollToGroupBox(System.Windows.Controls.GroupBox groupBox)
{
groupBox.BringIntoView();
}
