當使用.NET和WinForms創建可滾動的用戶控件時，我反覆遇到以下情況：例如，垂直滾動條彈出，重疊控件的內容，導致還需要水平滾動條。理想情況下，內容會縮小一點，爲垂直滾動條騰出空間。如何確保滾動條不會與內容重疊？
我目前的解決方案是讓我的控件保持在最右邊的40個像素左右，垂直滾動條將會佔用。由於這仍然是控件的有效客戶端空間，因此即使沒有控件完全隱藏，水平滾動條仍然會在垂直滾動條覆蓋時出現。但至少用戶實際上並不需要使用出現的水平滾動條。
有沒有更好的方法使這一切工作？一些方法來保持不需要的和不需要的滾動條顯示？
您將需要您的控件稍微調整大小以適應垂直滾動條的寬度。通過對接實現這一目標的一種方法。而不是僅僅放在窗體上的控件，你必須玩面板，填充，最小/最大尺寸和對接。
以下是您可以放置在空白的新Form1後面的示例代碼。在設計器或運行時調整窗體大小，您將看到水平滾動條未顯示，且字段不重疊。我也給了一個最大寬度爲好措施的領域：

如果您的控件位於面板內，請嘗試將面板的AutoScroll屬性設置爲False。這將隱藏滾動條。我希望這可以讓你指出正確的方向。
