Bug report

When we have a scenario with the Upload component configured with a chunk upload configuration, we cannot upload a file that contains an apostrophe in its name.

• The reported issue is not reproducing when the Upload is used inside a form or when it is configured to work in Asynchronous mode.
• The reported issue is also no reproducing when we try to upload a file that contains the ( ` ) symbol. It is replicated only when the apostrophe is in the filename

Reproduction of the problem

1. Open this demo
2. Upload the Dr's notes.pdf file from the below archive
   TestFiles.zip

Current behavior

The selected for upload file is not being uploaded.

** If the above scenario is tested in an MVC project, the error returned from the server is "A potentially dangerous Request.Form value was detected from the client". Below you will find a test project:
ChunkUpload.zip

Expected/desired behavior

The files selected for upload should not have any issues with their uploading, no matter if there is an apostrophe in their name or not.

Bug report

There are no configuration options dedicated to localizing the text in the arial-label attribute of these buttons. We localize other buttons, such as the "remove" and "cancel" buttons.

Reproduction of the problem

Dojo example.

1. Select a bigger file, which will allow the "pause" and "resume" buttons to appear.

Current behavior

The aria-label value is in English.

Expected/desired behavior

The aria-label value is localized.

Filter just certain types of files by extension (.csv, .doc, .jpg, etc.).

If we have a upload control with simple validation on allowed extensions and upload 50 files, the "k-upload-status" element prematurely gets set to "Done" once it finds a file type that is not allowed.  If a user is not paying attention they could think that the upload is complete.  It seems silly to mark an entire queue of files as "Done" after the first failure while uploading multiple items and while items are still uploading.  While the upload may technically be "done" it really failed and should say "Partially done" or some other message than "Done".

Also, placing an exclamation icon next to done is not very clear when an file does legitimately fail.  The icon needs to be more prevalent and have a tooltip to describe it further.  Most of my users in production have not noticed the icon and have thought that the upload completed.  This is especially a problem if a user is uploading thousands of files and does not scroll down during/after upload.

Scenario: Imagine you implemented upload widget within grid and it can upload multiple files. After you upload, you realize you need to delete one of the uploaded file. Currently you cannot choose to delete either of the uploaded multiple files in edit mode. It would be nice to display preuploaded files in upload widget when the grid is in edit mode, so that user can delete the files that are not necessary anymore.

Upload for MVC lucks upload in chunks feature as upload for ajax. So it is impossible to upload large files (like more than technical limit for asp.net in 4Gb). In my current project with 360 degrees videos where files might be 10+ Gb it is vital.

can refer http://tus.io/demo.html for resumable file upload.
and http://www.dropzonejs.com/ for drop zone.
its beautiful and important plugin. hope fully kendo can intergrated.

The upload control takes up a lot of space on the web page when you upload a lot of files.  As each file completes, I want an easy way to remove those files.  Ideally, a configuration option to automatically remove completed files otherwise a function to remove the file from the list from within the Success event.

When we upload files with the Kendo Upload, it would be nice to upload them sequentially, in separate requests

Provide the image preview option for kendo upload.

i really needed Upload By Folder like goolge drive uploader. i hope kendo will add that feature.

The suggested way to omit the Remove button is to not provide a Remove URL/Action.  However this breaks the list of the async upload such that the list doesn't get cleared with each new upload.  Since its an async upload that automatically uploads, there no point in accumulating a list of uploads.  Whether or not you expose a remove button shouldn't be tied in any way to the clearing of the list when a new upload is made.  That should only affect the availability of a remove button. At the very least you could provide some documentation on this quirky behavior.  Instead its random walk of, ok if I change this property what happens, how about this one, how about both, and whirl away a few hours screwing around with unpredictable behaviors.


    @(Html.Kendo().Upload()
                .Name("pdfFiles")
                .Multiple(false)
                .Async(configuration=> configuration
                    .AutoUpload(true)
                    .Save("UploadTemporaryPdf", "StatementOfCredit")
                    //.Remove("RemoveTemporaryPdf", "StatementOfCredit")
                )
                .Events(events=> events
                    .Select("onUploadSelect")
                    .Success("onUploadSuccess")                    
                    .Error("onUploadError")
                 )
                .HtmlAttributes(new { accept = "application/pdf" })

Add support to the Upload widget to upload files to an OData service, for instance to add attachments to SharePoint list items using SharePoints OData service. 

At the same time it would be good to be able to specify the urls for the Upload widget in an upload-datasource in a view model to which the Upload widget is databound, basically separate the uploading from the widget. That way you can choose to use an OData upload-datasource or a multipart/form-data upload-datasource. Obviously this OData upload-datasource may only be supported in browsers that support the HTML5 file api.
