Bug report

Scenario 1: When you first select an invalid file and then a valid one, the upload button appears but does nothing.

Scenario 2: When you select a valid file and then an invalid one, if you hit the upload button, the widget will try to upload the invalid one and produce a server error.

Reproduction of the problem

Scenario 1

1. Open this demo - https://demos.telerik.com/kendo-ui/upload/index
2. Select a .PNG or another invalid file.
3. Select a PDF ( or another valid file)

Scenario 2

3. Select a PNG ( or another invalid file)
4. Press Upload button

Current behavior

Scenario 1
The Button appears but does nothing

Scenario 2
The widget attempts to Upload the invalid file and produces an error

Expected/desired behavior

Upload of invalid files shouldn't occur and no errors should be thrown;
A non-responding Upload button shouldn't appear.

Environment

• Kendo UI version: 2022.3.913
• Browser: [all]

Currently, the DropZone is always rendered around the Telerik UI Upload widget and there is no built-in option that can be used in order to not render the DropZone. 

In order to hide the DropZone, the following is required:

<style>
     #wrapper {
       display: inline-block;
     }

     .k-upload {
       border-width: 0;
     }

     .k-upload .k-dropzone {
       padding: 0;
     }

     .k-upload-status-total {
       display: none;
     }
   </style>
<script>
    $(document).ready(function() {
      //Removing the "Drop files here message"
      $("#files").closest(".k-upload").find(".k-dropzone em").remove();
    });
  </script>

However, if Boostrap is used, additional steps are needed - all the necessary classes should be returned accordingly:

<script>
  $("#files").ready(function(){
       $("#files").closest(".k-dropzone").removeClass("k-dropzone").addClass("form-control").addClass("col-md-3");
   });
</script>

Hi Team,

I would like to request a built-in event which would fire when any validation fails within the Kendo UI Upload.  

Thank you!

Hi Team, 

I would like to request the functionality to remove the Drag and Drop upload configuration using the built-in API of the Kendo UI Upload. 

Thank you!

Hello,

It appears that the Upload control is not including the header: X-Requested-With when using it in Async mode. Omitting this header is a departure from the way the other controls behave in asnyc mode. It's inconsistent and leads developers to not be able to rely on features/behaviors of the supplied the controls.

Please consider adding this header as it will bring this control functionally in-line with the behavior of other controls running in async mode.

Thanks,

Mike

With the upload contronl when I select many items at one time it create un bunch of files can be upload in same batch. But when I select many files in different selection the control create bunch for every selection. For validation purpose I need to get all files in a single upload, but I cant control how the user select his files.

Actual                                                                           Expected

Bug report

The getFiles method does not return correct results when used in the success event. If you upload a file, the method in the success event will return an array with one item. If you remove a file, the same would return again an array with one item.

Reproduction of the problem

1. Open this Dojo example.
2. Upload a file and open the console.
3. Remove the file.

Current behavior

GetFiles returns an array with one item after removing the file from the list.

Expected/desired behavior

The method should return an empty array.

Environment

• Kendo UI version: 2020.1.406
• Browser: [all]

Bug report

The complete event is triggered after each file upload if chunkSize is set.

Reproduction of the problem

1. Open this Dojo example.
2. Select at least two files to be uploaded.

Current behavior

The complete event is triggered for each file after the uploading is done.

Expected/desired behavior

The complete event should trigger only once when the upload process for all files is completed.

Workaround in this Dojo example

Environment

• Kendo UI version: 2020.1.114
• Browser: [all]

Implement functionality that enables the dynamic change of the chunk size when uploading a file.

This change should depend on file size and upload speed. 

Reproduction of the Problem:

Dojo: http://dojo.telerik.com/@grabbi/ayiQOGoT

• Select multiple files in Upload-Widget with not allowed extensions or filesize greater then allowed
• Remove one File from the list (not the last one)
• Then the upload of the next file starts

This behaivior only occures when Chunk Upload is selected and some kind of validation is activated too.

Expected behaivior:

When Removing a file the file is just removed from the list and no upload ist starting.

Code:

<input name="file" id="file" type="file" />

<script>

</script>

Hello,

I came across an issue in Kendo Upload UI for Vue. The tooltip is not getting changed on file drag. I could reproduce the same in the official kendo website.

Please find the screenshot below

Would you consider adding a property for "FileSource" to the Files option of the upload widget?  Then i could set the base 64 string (since the images are stored in the database).  This would make it so much easier to display an image preview for these files.  Right now I have to do a hack because this is not supported (see ticketID: 1348670).  Please consider adding this property for the next version - thank you!

Here is what the code would look like with the new property available: 

                    .Files(files =>
                    {
                        foreach (var file in Model.Attachments)
                        {
                            files.Add().Name(file.FileName).Extension(file.Extension).Size(file.Size).FileSource(file.Base64Src);
                        }
                    }

Hi Team, I suggest the feature which can be copy and paste image while upload images. 
For fashion industry, we handle many images of clothes and we need to upload image to legacy system. 
However, we don't upload images by drag drop of them. We add the arrows, shapes and some texts about the image on the Excel
As of now, we capture all of them and put the image editing tool and then save and upload. so, if there's new feature which can be paste from clipboard, it'll be save much time for many person.

It would be very helpful if you could standardize the button configuration across all widgets to have the same styling and usage properties. Specifically, the KendoUploader button does not have the configuration options for spriteCssClass, icon, or imageUrl. It is possible to add a background icon via css, but in some cases a texture or other background icon may be used across the entire button, making it very difficult to apply a icon as a background to the button also.

Telerik Upload is lacking image preview and scaling options. Please add support to show a thumbnail of images before uploading and also the ability to resize images on the client. This is really important when you have people wanting to upload photos and they select big files when you only need a small image. Images can be scaled server side but much faster upload and more convenient client side.

Examples of free components that already do this:
https://www.plupload.com/
https://nodeca.github.io/pica/demo/

When uploading a file the option "allowedExtensions" cares about the case sensitivity and blocks f.e. a file called "image.PNG" when allowedExtension is set to "png" (lower cased). 

Expected: Case sensitivity will be ignored or could be activated/deactivated by another option.

I would like to have Kendo upload widget in a popup window to track the upload progress, while user navigate through different child pages in asp.net master page application. 
Larger file upload will take time and it will be very useful to have such a capability progress through the upload while user able to perform other things.
