i write a loop to get all paths of documents(images) from grid view and print all but when result number is about 20000 and above my website hanged i want to know away to divide these documents or print these number of images

推荐答案

我不能说为什么网站被挂起但是在您打印所有文档的情况下（现在可能是20,000个，但将来会更多）那么为什么不从数据库中获取打印页面中所有这些文档的列表？我不认为将大量记录从一个页面传输到另一个页面是个好主意。另外，我认为问题可能出在您的打印页面上。只需在该页面中设置一个断点并开始仔细调试;你会自己了解这个问题。

I can't say why the website is hanged but in the scenario where you are printing all the documents (which may be 20,000 for now but more in future) then why don't you get the list of all those documents in the Print page from the database? I don't think it is a good idea to transfer that much big number of records from one page to another. Also, I think the issue could be in your Printing page. Just put a break point in that page and start debugging carefully; you will get to know the problem yourself.
