For the future it would be nice if a separate "move" endpoint was optionally available since many of us tend to use virtual filesystem layouts instead of real filsystems.

That said, I used the advice here to setup my own custom handling for file moves:

FileManager - Detect move vs copy in UI for ASP.NET MVC | Telerik Forums

If I preventDefault, I can only do 1-2 moves before I am then unable to navigate the folders anymore through either column. If I allow it to propogate and fire off the create and destroy request (my serverside functions ignore these as invalid), the navigation continues to work.

Can you suggest what events I can maybe fire manually to trigger success without making the create and destroy request, or suggest another way to fix this issue?

My move handler:

function onexecute(e) {
        if (e.command == "MoveCommand") {

            var d = {
                'items' : e.options.items,
                'targetfolder' : e.options.target
            };

            $.post('/Data/Gallery_move?aid=@Model.Asset.ID', d)/*, function(data){
            });*/
            
            //e.preventDefault();
        }
    }

Bug report

When an item is selected in the left panel and setDataSource is used in FileManager, the left panel becomes empty. The behavior does not occur if the setDataSource method is used without previously selecting an item.

Reproduction of the problem

1. Open the Dojo.
2. Select the 'Documents' folder
3. Click on the 'Reset data' button.

Current behavior

The left panel in FileManager becomes empty.

Expected/desired behavior

The newly set folders should be displayed even if an item is selected before setting the new dataSource.

Moving files MORE than one level upwards in a folder hierarchy is bugged.

If you have a nested folder hierarchy like this:

folder1

          folder2

                   folder3

1. moving a file from folder1 to folder2 works.

2. moving a file from folder2 to folder1 works.

3. moving a file from folder1 to folder3 works.

4. moving a file from folder3 to folder1 is BUGGED.

I have the issue in my code, but I also tested it in your demo site and it has the same problem.

https://demos.telerik.com/kendo-ui/filemanager/index

I have uploaded a screen dump of the error output from Chrome.

It is in or after the DataBinding event (Comming from Create action), the the error occurs, thus causing the Delete action and refresh of the UI to never occur.

The bug occurs in both Chrome and IE Edge.

Please fix the bug.

I am running into inconsistencies when using the toolbar Search input of a File Manager object after navigating to new folders.  

Simple dojo for reference - https://dojo.telerik.com/aPOtiXex/2

Steps to reproduce

1. Click on "Folder1" in the treeview.
2. In the Toolbar Search, enter the text "Sub 1001".  This will correctly filter the displayed items.
3. Click on "Sub 1001" in the treeview.  Notice that the search filter is still in place, but that it is not applied to the current folder view.
4. In the Toolbar Search, remove the text 1 character at a time.  Notice that as you remove characters in the Search input, the filter IS applied to the current folder view.  Continue removing characters until the Search input is empty.
5. Click on "Folder1" in the treeview.  Notice that the contents of the folder are STILL filtered as if the Search filter was "Sub 1001", even though Search input is currently empty.
6. In the Toolbar Search, add 1 space character, then remove it.  Notice that this finally clears the filter applied to the folcer in step #2.

I am not sure what the best answer for this scenario would be.  Maybe navigating to a new folder should clear the search filter criteria in the toolbar and clear any applied filter criteria to the previous folder?  Or maybe the toolbar search input should be reset to accurately reflect the current applied filter for the folder on navigate?  Something good for your dev team to discuss, but it is clear that the current implementation will create some confusion for users.

Bug report

In FileManager read request is triggered twice when navigating to a parent folder that has a nested folder. The issue does not occur if the folder contains only files without a nested folder.

Reproduction of the problem

1. The issue can be replicated if a nested folder is created in the demo service. The screencast here demonstrates the issue.

Current behavior

Two identical requests are sent when the parent folder is selected.

Expected/desired behavior

There should be a single request when navigating to a parent folder, even if it has a nested child folder.

3. Select Folder Inner 1
4. Collapse Root
5. Re-expand Root

Calling the loaded method on a FileEntry instance does not reset the loaded flag.

function onNavigate(e) {
            var filemanager = e.sender;
            var path = e.path;
            var entry = filemanager.dataSource.get(path);
            if (entry.loaded()) {
                entry.loaded(false);
            }
        }

Reproduction of the problem

1. Run this dojo
2. On the TreeView section of the Filemanager navigate to both folders, so the contents of the folders are loaded
3. Navigate between the Folders using the TreeView and note the loaded flag is not reset

Current behavior

Calling entry.loaded(false); does not reset the loaded flag of a FileEntry instance.

Expected/desired behavior

Calling entry.loaded(false); should reset the loaded flag of a FileEntry instance.

In mobile devices, when a nested folder is renamed in the FileManager, the parent folder is displayed in the dialog for renaming.

Reproduction of the problem

2. Create a nested folder and try to rename it.

Current behavior

The parent folder name is displayed in the dialog for renaming. The parent folder is renamed after saving (screencast)

Feature Request

The tooltip for the ListView button (ListView) in the FileManager is misleading. Consider renaming it to "thumbnails" or less confusing text. Currently, it leads to the impression that the items would be represented as normal list instead of as items in the ListView widget.

Expected/desired behavior

Less confusing text should be used for tooltip for the ListView button.
