We allow the user to rename files and folders, but if they rename to the same name as another file/folder, what we would like to do is prompt the user with a confirmation dialog, explaining that if they click "Ok", the existing file will be overwritten with the newly-renamed file.  For folders, it would merge the contents, but again, duplicates would be overwritten.  If they click "Cancel", then the dialog should close, and nothing else should happen.  

Right now, the closest thing I could find was the "requestStart" event handler.  This fires after the user renames, and before the request is sent to the server.  The problem is, even in the documentation, it says, "This event can be prevented only for read requests."  

We would like to be able to prevent "update" requests as well, for this scenario.  Can this be added as a feature? 

Hi Team,

I would like to request to add Wildcards to the Search panel for the Kendo UI FileManager. 

Thank you!

Environment

• Browser: [all ]

I'm trying to use the delete context method, but when selecting multiple folders and deleting them it sends the same delete request multiple times. The more folders (no subfolders) I try to delete the more requests it sends.

My theory is that the datasource somehow doesn't register it has been deleted, so it tries to automatically sync the datasource by sending it again. Note that I'm using a virutal filesystem, but I'm returning the same object as in this sample

Also note that I'm using a mix of MVC and Jquery so I have a custom scheme as recommended in some of my previous tickets.

This is scheme:

        $.extend(true, kendo.data, {
            schemas: {
                "filemanager": {
                    data: function (data) {
                        return data.Items || data || [];
                    },
                    model: {
                        id: "path",
                        hasChildren: "hasDirectories",
                        fields: {
                            entryId: { field: "EntryId", editable: false, type: "Number" },
                            folderId: { field: "FolderId", editable: false, type: "Number" },
                            name: { field: "Name", editable: true, type: "String", defaultValue: "New Folder" },
                            size: { field: "Size", editable: false, type: "Number" },
                            path: { field: "Path", editable: false, type: "String" },
                            extension: { field: "Extension", editable: false, type: "String" },
                            isDirectory: { field: "IsDirectory", editable: false, defaultValue: true, type: "Boolean" },
                            hasDirectories: { field: "HasDirectories", editable: false, defaultValue: false, type: "Boolean" },
                            created: { field: "Created", type: "Date", editable: false },
                            createdUtc: { field: "CreatedUtc", type: "Date", editable: false },
                            modified: { field: "Modified", type: "Date", editable: false },
                            modifiedUtc: { field: "ModifiedUtc", type: "Date", editable: false }
                        }
                    }
                }
            }
        });

        $("#document-manager").kendoFileManager({
            dataSource: {
                transport: {
                    read: {
                        type: "post",
                        url: "/FileManager/Read",
                        data: function() {
                            return getFileMetaData()
                        }
                    },
                    update: {
                        type: "post",
                        url: "/FileManager/Rename",
                    },
                    create: {
                        type: "post",
                        url: "/FileManager/Create",
                        data: function () {
                            return getFileMetaData()
                        }
                    },
                    destroy: {
                        type: "post",
                        url: "/FileManager/DeleteEntry"
                    }
                },
            },
            contextMenu: {
                items: [
                    { name: "rename" },
                    { name: "delete" }
                ]
            },
        });

And lastly my C# controller method which deletes the folder and returns the same object as in the above mentioned sample:

        [HttpPost]
        public async Task<ActionResult> DeleteEntry(FileManagerEntry deleteDto)
        {
            await _fileManagerService.DeleteEntry(deleteDto);

            return Json(new object[0], JsonRequestBehavior.AllowGet);
        }

You can also see in this screencast that it sends the delete request multiple times for the same entry:

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();
        }
    }

There is no padding between semicolon and the data "Type:Folder" wouldn't be better "Type: folder" with a space in between?

This one is a bit complex:

1. Run sample at https://dojo.telerik.com/@GaloisGirl/IPAMIHik
2. Enter folder "Documents"
3. Delete "ExcelDocument.xslx" - the operation should fail and the file will come back.
4. Delete "Text.txt" - no request is sent, the file does not come back

Any "delete" operation can be replaced by a "rename" operation, and the result is the same.

The problem does not happen at root level. I don't know if it's because it's the root levels, or because the elements are directories.

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.
