讓控制元件隨窗體大小變化而變化~WinForms控制元件自適應窗體大小
阿新 • • 發佈：2019-01-22
簡單的來說就是監控，定位+保持比例。
例如介面分為左右下三部分，其中下部分最好解決。使用Dock屬性直接定位到Bottom。難點就是上面的左右兩塊。
我的做法是：外面套一層，然後分割為左右兩部分。這裡採用TableLayoutPanel為例。將TableLayoutPanel調整為一行兩列左右各佔50%的單元格形式。
並將TableLayoutPanel的Dock屬性調整為Fill。這樣兩個控制元件就會各占上下兩部分。
這時候可以執行，會發現無論窗體大小怎麼變，控制元件都是會自動調整。不會死板板的。
下面是重點：
放兩個需要測試的控制元件分別到TableLayoutPanel的兩個單元格中。我這裡放的是ListBox。然後將兩個ListBox的Anchor屬性都設為Top,Bottom,Left,Right。既上下左右。最後調整兩個ListBox到合適大小。好了，完事。。。
下面貼出的是Designer部分的程式碼。直接貼上進去看效果吧
