[Solved] RadGrid Export function

[Joe]

Hi,

We have a gird with a export function. It works very well. However, when there are 5000 items in the grid. Once fire the export function, it will give a exception:"

System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

"

I was wondering if export function has a maximum limit or if you have any solution for this.

I appreciate your help

Thanks,
Feng

Hello Joe,

In my opinion the problem is either caused by firewall or by restriction in web.config:

Thank you for your reply.
Actually, it works when there are about 1500 items in the grid, but it crash when there are 5000. So I don't think it's the firewall problem.
In the web.config, I didn't find the maxRequestLength. WCF configuration set the time to 1 minute and maximum size was 5MB. The file I estimated that contain 5000 items was less than 1 MB, which is still much less than 4MB.

Do you have any other idea?

Thank you,

Hi,

I also increase the maxRequestLength to 800MB, but the error persist...

Thanks,

Timeout issue?

Not sure. the exception was thrown very quickly. In 2 seconds after I click the export button.
