今天有人問我這樣的問題:
"Silverlight 可以依照Client端螢幕解析度大小,來自動調整Silverlight顯示大小嗎?"
那我第一個想法就是 : "OF COURSE!~"
今天有人問我這樣的問題:
"Silverlight 可以依照Client端螢幕解析度大小,來自動調整Silverlight顯示大小嗎?"
那我第一個想法就是 : "OF COURSE!~"
ex:
如果原本自己設計的 Silverlight 版型是 1024x768 的規格,也就是 LayoutRoot 的大小
如果改成 800x600 的解析度, 那你再Broswer 右邊就會出現討厭的捲軸
那我的想法,要做這個功能的話:
1) 先取得Client Broswer的解析度(重點)
2) 再用程式碼計算如何"縮放"你SL的元件(預設:LayoutRoot , 元件=Grid)

就這樣~將這個類別放在你的程式碼之中即可~(已測試OK)
