循环 AdvancedDataGrid 时出现问题

发布于 2024-10-02 03:44:55 字数 352 浏览 4 评论 0原文

我需要循环遍历 AdvancedDataGrid 的树。谁能给我解释一些事情吗？

这是我的代码：

var adg : AdvancedDataGrid;

var dp : GroupingCollection2 = adg.dataProvider;
var cursor:IViewCursor=dp.createCursor();

现在我的问题是我不知道如何从这里访问我的对象。我的 AdvancedDataGrid 有一个 GroupingCollection2 作为数据提供者，它以 XML 作为源，并且还按 XML 中的“Project_Name”字段进行分组。

有什么建议吗？

I need to loop through an AdvancedDataGrid's tree. Can anyone explain me some things?

This is my code:

var adg : AdvancedDataGrid;

var dp : GroupingCollection2 = adg.dataProvider;
var cursor:IViewCursor=dp.createCursor();

Now my issue is that I don't know how to access my objects from here. My AdvancedDataGrid has as dataprovider an GroupingCollection2 that has an XML as source, and also is grouped by "Project_Name" field from XML.

Any advice?

像这样的东西？

var dp:Object=MyDG.dataProvider;
var cursor:IViewCursor=dp.createCursor();

while( !cursor.afterLast )
{
// Access each column field like: cursor.current.MyFieldName
trace(cursor.current.MyFieldName);
// Obviously don't forget to move to next row:
cursor.moveNext();
}
