Folder navigation issue

[Responsive]

I'm implementing a file manager in an MVC site that works with files located somewhere other than the site. I have got this working fine as long as I stay in the root directory. Trying to change into another directory throws the following error in the console:

 

Error! Could not navigate to the folder at the requested path(/Message Attachments). Make sure that the parent folder of the target folder has already been loaded.

As changing directories doesn't seem to be triggering anything on the server, I'm at a loss as to how to troubleshoot this.

The code in the view is pretty much right out of the demo at this point:

@(Html.Kendo().FileManager().Name("filemanager")
    .DataSource(ds =>
        {
            ds.Read(operation => operation
            .Type(HttpVerbs.Post)
            .Action("Read", "Documents")
        );
        ds.Destroy(operation => operation
            .Type(HttpVerbs.Post)
            .Action("Destroy", "Documents")
        );
        ds.Create(operation => operation
            .Type(HttpVerbs.Post)
            .Action("Create", "Documents")
        );
        ds.Update(operation => operation
            .Type(HttpVerbs.Post)
            .Action("Update", "Documents")
        );
    })
    .UploadUrl("Upload", "Documents")
    .Toolbar(tb => tb.Items(items =>
    {
        items.Add("createFolder");
        items.Add("upload");
        items.Add("sortDirection");
        items.Add("sortField");
        items.Add("changeView");
        items.Add("spacer");
        items.Add("details");
        items.Add("search");
    }))
    .ContextMenu(context => context.Items(items =>
    {
        items.Add("rename");
        items.Add("delete");
    }))
)

Hi, Responsive,

I've just sent you a reply in the Support ticket that discusses the same topic as the current one.

To keep the communication consistent, let's continue it in the private support thread.

Hey Petar,

So, what was the solution?  I am having the same issue.

Thanks.

Hi Brent,

What I've done in the support ticket is to send Responsive the attached project and ask for a comparison of the provided example and the implementation on their end. 

The issue was related to a backslash that was missed but I don't have more details I can share.

What you can do is compare the attached example to the FileManager's implementation in your app. Thus you may identify what is the reason for the error that you get. To run the project, you will have to add the Kendo.MVC DLL file in the lib folder of the provided example.

If the projects' comparison doesn't resolve your issue, to be able to help you, I will need a runnable example in which the error that you get can be replicated. Send me such a project and I will furhter investigate the reason for the unexpected behavior.

I am currently having the same issue when trying to refresh in the navigate event: 

navigate: function(e) {
      e.sender.refresh();
}

Gives me the same error - "Could not navigate to folder at the requested path (\\path). Make sure that the parent folder of the target folder has already been loaded".

I would like to implement this so that the files in the widget stay updated to match what's in the file system without having to refresh the whole page.

Hi Anna,

The pointed issue is probably caused by the custom implementation as per the needs of your application. For further investigation, I will need a runnable sample of your project and will try my best to resolve the case.

The following dojo example is representing the pointed implementation and it is working out of the box:

• https://dojo.telerik.com/@anton.mironov/orOgoqAM

Furthermore, you could try to replicate the issue in the dojo example above and send it back to me in this thread.

Looking forward to hearing back from you.

Kind Regards,
