I'm using CF to retrieve values from a database that are then being stored in a datagrid in Flex. I then want to selectively take the value from one cell of the datagrid and store it as a string variable. I've searched around, but I haven't been able to come about a solution. The users will not be interacting at all with the datagrid as it will be hidden to them. Any help?

推荐答案

你为什么要费心去使用一个DataGrid，如果它是的隐藏的用户？将资料储存在对象的ArrayCollection或XML文档中访问。装载了一个重量级的用户控件只被无形的不必要的处理时间和浪费开发时间。在任何情况下，你的方式得到大块出一个DataGrid或的AdvancedDataGrid是访问其dataProvider和操作的是的。只要消除中间人在这里，你应该罚款。

Why are you bothering to use a DataGrid if it is hidden to the user? Store your data in an ArrayCollection of objects or in an XML document and access that. Loading up a heavyweight user control just to be invisible is unnecessary processing time and wasted development time. In any case, the way you get chunks out of a DataGrid or AdvancedDataGrid is to access its dataProvider and manipulate that. Just eliminate the "middle man" here and you should be fine.
