Monodroid：當我滾動視圖時，TeeCharts消失

我應該在運行時添加4個teechart控件。我能夠將這些值綁定到teechart控件。Monodroid：當我滾動視圖時，TeeCharts消失

問題是，當我滾動父視圖時，所有teecharts消失。但所有其他控件都可見（按鈕，文本視圖等）。

注意：最初所有控件都是可見的;他們只有在我滾動時纔會消失。

另一位用戶最近報道了類似的問題（TM63016590）時Zoom.Style設置爲ZoomStyles.Classic。我們對此有一個修復建議，可在https://www.steema.com/downloads/net_android的當前評估版中找到。您能否讓我們知道它是否能解決您的問題？

請檢查上面的代碼..其已經存在。 rainfallChart.Zoom.Style = Steema.TeeChart.ZoomStyles.Classic; – user2330792

@ user2330792是的，所以我看到了。這就是爲什麼我建議使用測試版固定TM63016590。如果您向我們發送一個簡單的示例項目，我們可以「按原樣」運行以重現此問題，但我很樂意測試問題是否得到解決。您可以在www.steema.net/upload/上發佈您的文件。或者，您可以嘗試使用其他ZoomStyles選項。 –

我嘗試了所有其他選項。沒有工作。我得到鏈接http://www.steema.net/upload/的配置錯誤。我如何向你發送示例代碼。請給我你的電子郵件ID。 – user2330792
