DevExtreme - File Manager Component CTP (v19.1)

Thank you, the component was missing under Devextreme

Wishes:

1) Button(switchable) and client function(!) to change the view mode (ThumbnailView and DetailView)

2) Adaptability

3) Make light colored icons. It is desirable that this is switched without switching the theme, and just in the component was the ability to select a set of icons.

And please bring the first two items to colleagues in ASPxFileManager for WebForms/MVC set.

By the way, I also noticed that it is written that Angular, React, and Vue are not yet supported in the CTP version. Why then in Filemanager is mentioned in What's a new in 19.1 in the DevExtreme JavaScript Controls v19.1 section? All the same will be in 19.1? Or just under ASP.NET MVC / Core?

Will it be possible to add custom columns?

I was looking for this just a couple of weeks back, such a great component of the MVC Controls, great to see it ported over to DevExtreme.

Great job as always DevExpress!

It would be a very useful component, specially dealing with security.

Does it support to select a folder and then entire folder copied to a server folder instead of selecting each file checkbox?

Hi Team,

Ongoing with your feature list, you have mentioned the API are REST full for the file manager.

How could check your REST API  in the below link?

https://resttesttest.com/

And also I have noticed that  you have used the POST HTTP method instead of READ to read the files, is it valid one ?.

Kindly advice on this.

Where is the documentation for client-side events? How does one respond to mouse events, etc? Are there any drag/drop capabilities?

We have an immediate need to create an image library with folders and sub folders, but need to a) integrate with the File Upload component and b) show thumbnails of multiple images in a given folder and subfolder.  We are using jQuery on the front end and ASP.Net Web API Core (no Razor, or front end dependencies) on the back end.

Hi Team, is there any plan to add a thumbnail image of the file on the server.  In other words if you go into a file with 20 images, it must show the thumbnail of the 20 images so you can select which image you want to use?  (Similar to how windows will show it on the client side), but this will be for files on the server side.

I do realize, the server will have to render a thumbnail of the image.  I'm using Razor pages, and this could be a very useful add-on to the server side if this widget for razor pages.

ok, I'm obviously still new in the dotnet and razor.  But found the solution to my question.

 customizeThumbnail: function (fileManagerItem) {

                var fileExtension = fileManagerItem.getExtension();

                if (fileManagerItem.isDirectory)

                    return '@Url.Content("~/images/thumbnails/folder.svg")';

                var f = fileManagerItem.relativeName;

                console.log(f);

                 switch (fileExtension) {

                     case ".jpg":

                          var url = '@Url.Content("~/xxx")';

                            url = url.replace("xxx", f);

                        return url;

                        break;

                    case ".png":

                        var url = '@Url.Content("~/xxx")';

                            url = url.replace("xxx", f);

                        return url;

                        break;

                }

            }

So the functionality obviously already exist, and work like a charm.  Great!!

Just found the selectedFileOpened event and is triggered by double clicking a file. Just have to implement the download using info in the fileItem object passed in.
