用于添加動態元素的WPF滾動查看器

我需要有關我的 WPF 應用程式的幫助。在我的視窗底部，我有一個畫布，其中動態填充了組框，其中包含幾個用戶元素，如按鈕和網格視圖。插入的內容在我的視窗之外，我想用滾動條訪問它，但滾動條沒有調整，所以我無法訪問這些元素。

如何使用滾動條訪問內容？

謝謝你的幫助。

uj5u.com熱心網友回復：

您的專案超出了畫布邊界，畫布未調整大小且 ScrollView 未應用。

順便說一句，我不建議您為此目的使用畫布。還有很多其他的布局會給你一個更好的結果，比如 StackPanel 或 WrapPanel，如果你給 WrapPanel 一個寬度，它會很好地重新排列你的專案。
