Stackpanels并排(Stackpanels side by side)

 我想把stackPanels放在一起。 然后在每个堆栈面板中，有不同的控件。 现在第一个堆栈面板正在工作。 它有文本块和文本框。 现在我想在第二个堆栈面板上添加一个按钮，依此类推。 问题是第二个面板没有显示按钮的内容。 不知道为什么？

I want to put stackPanels side by side. Then in each stack panel, there are different controls. Now the first stack panel is working. It has textblocks and text boxs. Now I want to add a button on the second stack panel and so on. The question is that the second panel doesn't show the button's content. Not sure why?

 当一个进程（任何进程，而不仅仅是一个.Net进程）终止时， 没有 100％可靠的机制可以用来保存数据（或者做其他任何事情） - 大多数进程可以在任何时候使用“结束进程“选项，当发生这种情况时，进程立即被终止。 作为一个更极端的例子，电源线可以从机器背面拔出。  
 如果该数据对象不是100％必须保持最新状态，并且一旦进程被终止，那么AppDomain.UnhandledException事件就足够了。  
 如果这绝对是100％必要的，那么在流程运行时，您需要不断保存这些信息 - 绝对没有保证您有机会在以后这样做。 这就是数据库的运作方式，只有某些格式的记录（例如事务日志）以某种格式记录到磁盘后，才会有事务返回。 这就是D在ACID中所代表的意思。 

There is no 100% reliable mechanism that you can use to save data (or do anything else for that matter) when a process (any process, not just a .Net process) terminates - most processes can be terminated at any point using the "End Process" option in the task manager, when this happens the process is immediately killed. As a more extreme example the power cord could be pulled out the back of the machine. 
If its not 100% necessary that this data object be up-to-date and saved once the process is killed then the AppDomain.UnhandledException Event may suffice. 
If its absolutely 100% necessary that this be the case then you need to be continuously saving this information as the process is running - there is absolutely no guarentee that you will get a chance to do it at a later date. This is how databases operate, no transaction returns until some record of the change has been recorded to disk in some format (e.g. a transaction log). This is what the D stands for in ACID.
