File Explorer Loading Problems / thinking mode

[Peyman]

hi dear telerik team :
it seems File Explorer has some problems when want to load a folder  / it goes to thinking mode / stay on loding.gif ajax mode!
this problem appeared aftre publish / my server speed is ok -> 5-6 mbps
but i do n't know how can i fix this issue?

Hi Peyman,

There are two main reasons for such problem to occur:

1. A custom AJAX request that is triggered along with the RadFileExplorer's request to populate the folder - RadFileExplorer is heavily based on client callbacks and it is highly not recommended to be externally ajaxified.
2. A server-side error has occurred during the RadFileExplorer's request preventing its correct execution. Could you check if the response is correctly returned from the server using FireBug?

In order to be able to provide more to the point answer, we will need to examine and debug the problem locally. Could you please provide a fully runnable sample project and / or a live URL reproducing the problem so we can examine the issue further?
All the best,

Hi Peyman,

Unfortunately, the provided live URL is not accessible. Could you please verify that this is the correct address and if it is available for public access?

so sorry about that,
my server is in poland and i do n't know what is going on about that domain!
plz use one of the below links :
Old File Explorer Link - Faster
New File Explorer Link - Not So Fast

[Peyman]

i did n't use any server side event for this control...
just one client side event (OpenFile) that it has nothing to do about this problem!
i am so sad about this issue...
any idea?

I wonder if it is a latency issue, I did see the problem, but it only happened when the site was running very very very slow. The load was horrible, then it happened. Refreshed and it was fine and fast and problem gone. Looks like you may want to check your host's internet connection, least fron where I am , Northeast PA. Response times are spuratic and I would think that has got to have something to do with it. Does it happen when you run the project locally?

[Peyman]

it seems in local we can not see this problem ->
but my first link is fast and we should n't have this problem on it , but we have!
besides what about users with low speed internet connection?

thanks in advance

[Peyman]

any idea ?
i am so sad about this problem!

[James Campbell]

What I see from my internet connection isn't just slowness here and there, I see complete loss of packets, meaning a loss of server client mid-communication. I would talk to your host, or even open ICMP, ping it for a bit like “ping YOURIPHERE – t > ping.txt”. Wait about a few minutes, look at the dropped packets, I’ll bet there are a few.

This is just an idea of what may be going on, Telerik would always know best, open a support ticket.

[Peyman]

but what about server #2...
both of them have this problem.
i think this problem has nothing to do with server problem!
any other idea?

[James Campbell]

Both seem to have some connection issues IMO from what I have seen. I also see the client requests going out from the control, but the server is not responding. This can be confirmed using something like fiddler: http://www.fiddler2.com/fiddler2/ .

Hello Payman,

I tried both links and was able to reproduce the problem only once, and I noticed that at this moment there was an interrupted AJAX request initiated by RadFileExplorer, I am not quite sure why this request was aborted, and I was not able to reproduce the problem once again.

However, when I decided to try it again yesterday, the links were changed and I was unable to examine the page again. Since you are not able to reproduce the problem locally and are able to observe it on the server, could you please check if there is an aborted AJAX request every time the problem occurs. If so, try to disable the AJAX on the page and test again. If the explorer keeps 'hanging' and its internal AJAX requests keep getting aborted, I would recommend you to contact the hosting company and ask for server logs.
