推荐答案

加快构建树视图的唯一方法是动态构建它.例如，如果开始时一切都已折叠，则无需加载子节点.然后，在扩展某些内容时，返回并获取孩子并填写他们.

打开节点时，您可能会稍有延迟，但是不喜欢一次加载所有内容……尤其是因为有7,000,000条记录，任何人查看所有记录的可能性可能约为0％.

The only way to speed up building a treeview is to build it dynamically. For instance, you don''t need to load the children nodes if you are starting out with everything collapsed. Then, when something is expanded, go back to access and get the children and fill them in.

You may have a slight delay when opening a node, but not like loading everything all at once...especially since with 7,000,000 records, the likelihood of anyone looking at all of them is probably around 0%.

这可能取决于数据读取的速度(方法)...:)

It may depend on the speed (method) of data reading... :)

谢谢.

实际上我现在知道了.

但是我无法通过这种方式填写7,000,000条记录


TreeList1.Items.add !FeilsName


看.
当我们将Dataset与数据源一起使用时，我们可以获得更快的方法来填充ListBox，例如

但循环会浪费更多时间

注意:我不需要子节点

Thank you.

In fact I now that.

But I cant fill 7,000,000 record by this way


TreeList1.Items.add !FeilsName


Look.
When We use Dataset with datasource we can get faster way to fill a ListBox for example

but by loop will lost more time

Note: I Don''t need child node
