Physical Paths

[OnionMan]

Has anyone managed to create a FileBrowserContentProvider to handle physical paths outside the web app? I have a scenario where I need files to be managed outside of the application, and it appears that everything wants virtual paths!

Looking at the demo I also thought of using a httphandler for the files, however that isn’t working. I got as far as getting the directory tree to show in the left tree view however no files are being shown.

I am by no means an ASP.net expert and am still learning the ropes, so if anyone can point me in the right direction I'd be most grateful.

I Keep getting errors like below thrown up:

---------------------------
Message from webpage
---------------------------
Callback Loading error:
D:\Test\
Unrecognized escape sequence. (14): { path : "D:\Test\", sortExpression : ""}96|/wEWCAL4tITjBwL8w9uGDALztZepDwLytZepDwL1tZepDwL0tZepDwLvtZepDwLutZepD4v1sVL6WoAl9jmHj5iuS6WymetQ

OK

Hello,

Which version of the RadControls are you using? Try getting the latest internal build from http://www.telerik.com/account/latest-internal-builds.aspx. It seems the problem is that the path we submit to the server is not properly escaped (the \ path separator needs to be escaped).

Kind regards,

Is there a fix to this issue yet, I too would like to use this for folders located outside of the web structure.

Hi,

I managed to get it working, still need to polish it up and work out some kinks. I am using a handler to provide the files, and as Lini said you need to escape the back slashes for the paths. Once its working correctly I will put it in the code gallery.

Hi Onionman,

We too are facing this issue. Currently FileBrowser is working only in case of files within the Web Application. But for our application, files will be in a shared folder like \\server\images and this does not work with the FileBrowser. Any updates on this is really appreciated. Thanks!

Regards,
Vivek

Hi Onionman,

I too have this issue, and would like to know how to use a shared folder (like \\server\folder) with the RadFileExplorer.

Hey guys,

I needed the fileviewer to view content from a network location,see the code below for a custom content provider solution to do so.

the code below shows the content provider that reads all the files and folders of the given path.

like I said its just for viewing so I didnt implement anything else (yet).
It's a start, take a look at it, it works for the network paths like vivek requested. I did not test it on physical paths but I expect it to work in the same way.

There is one but to this solution. If the network folder is protected by a domain user login, this will crash
when the GetFiles() method is called. In other words it won't work then.
Haven't found a solution for that (yet).

A other thing I noticed is that when using the Q2 2009 release open file might throw a JSON error.
Untill I know why I'm using the Q1 2009 where it works perfectly.

For a telerik employee I get the following message:
"Microsoft JScript runtime error: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.
Parameter name: data".

the call:

	FileExplorer1.Configuration.ContentProviderTypeName = typeof(NewWorkFileBrowserContentProvider).AssemblyQualifiedName;

Hi Fiko

I implemented the customfilebrowser using online resources available. I have network path outside the application and called using webservice to create/delete folder/file.

If I select a folder/subfolder, i get Cannot deserialize. The data does not correspond to valid JSON., and grid doesn't refresh.

Hello,

This error might occur if some of the results of some of RadFileExplorer's AJAX calls is corrupted. Are you, by any chance, tracking the response output at the page or application level (e.g. the response time of a page)?

To be able to provide more to the point answer we will need to examine and debug the issue. Could you, please, try to isolate the issue into a simple fully runnable project and send it for a further investigation?

Also, could you please provide a fiddler log captured the problematic scenario? You can find information how to work with this useful tool here: http://www.west-wind.com/weblog/posts/596348.aspx.

Looking forward to hearing from you,
