The current implementation of the AsyncUpload uses its built-in file appender methods, and we would like an option to customize this.

RadAsyncUpload "Drop Files here" element remains visible when dragging a file quickly over and out of the DragZone

Replicable in File Upload with Drag and Drop live demo.

Drag a file quickly through the DragZone without dropping it. The "Drop Files Here" element is shown but doesn't get hidden when the mouse leaves the DragZone (ondragleave).

Hi guys,

I can see async.concurrent feature in kendo ui upload control, do we have this feature or can have it in ajax upload control ? 

 

https://docs.telerik.com/kendo-ui/api/javascript/ui/upload/configuration/async.concurrent

Currently the AsyncUpload saves the chunks in the Temporary folder using the original name of the file, the Process method of the Custom handler. When the Temporary folder name is very long, it can hit the Windows path length limitation of 260 symbols.

Workaround - Toggle drop zone visibility or enable/disable it, using AsyncUpload OnClientFileUploaded and OnClientFileUploadRemoved events:

<div class="dropfile" style="height: 20px; width: 120px; background-color: red; display: block">
</div>
<telerik:RadAsyncUpload ID="fimFileImport" runat="server" DropZones=".dropfile" MaxFileInputsCount="1"
	RenderMode="Lightweight" OnClientFileUploaded="OnClientFileUploaded" OnClientFileUploadRemoved="OnClientFileUploadRemoved" >
</telerik:RadAsyncUpload>

<script type="text/javascript">
	function OnClientFileUploaded(sender, args) {

		var maxFileCount = sender.get_maxFileCount();
		var uploadedFilesLength = sender.getUploadedFiles().length;
		
		if (maxFileCount === uploadedFilesLength) {
			$telerik.$('.dropfile').hide();
		}
	}

	function OnClientFileUploadRemoved(sender, args) {

		var maxFileCount = sender.get_maxFileCount();
		var uploadedFilesLength = sender.getUploadedFiles().length;

		if (maxFileCount > uploadedFilesLength) {
			$telerik.$('.dropfile').show();
		}
	}
</script>

I am using the RadAsyncUpload with UploadedFilesRendering="BelowFileInput".  This works fine, but I would like the list to appear in the order they are selected not the reverse order.  Is there away to accomplish this?  It should look like the UploadedFilesRendering="AboveFileInput" list but appearing below.

This should be a feature of the control which currently limited to above in the order they are select or below the reverse order.  In either case you should be able to select the order the files are displayed in the UI.

We would like to upload a folder's structure and content via asyncupload drag and drop functionality.  This functionality exists with Chrome and FireFox now.  Please add.  Thanks.

One of the issues with the asyncuploader is the inability to be able to reorder the list.  There should be a way to allow for dragging and dropping the files in the desired order even after they've been uploaded to the list without having to delete the files only to upload them again in the required order.

When validation is set in order prevent a user from uploading an unsupported file, it works fine when the user uploads files with extensions.

The problem is, if the same user attempts to upload from a mobile device such as from google drive, the file typically has no extensions, and therefore it fails validation; even though it in fact is a supported file.

Somehow, when we know it's a mobile device, tablet, or a MAC we need to be able to allow no extensions.

Create an option or detect if it is be accessed from a mobile device, and allow us to choose if we want allow files to have no extensions, even if the validation is active so that if a file is uploaded without an extension in those cases it doesn't trigger the validation and fails clients side.

Please implement file filtering on the Open Dialog Window via the accepts property of the rendered HTML 5 input file control. 

The current implementation provides file filtering via flash or silverlight but this functionality is built into the <input type="file"/> control by adding the accepts property. In order to provide file filtering for all modern browsers, without using plugins, the accepts property would only need to be added to the already rendered file control. <input type="file" accepts="image/jpeg, image/gif" />

I have made this change via developer tools in each major browser and it worked fine across the HTML 5 compliant browsers (FF, Chrome, IE).

When upload larger files the connection may dropped during the file uploading. In result of this the selected file will not be uploaded successfully and the user will have to start the uploading from the beginning. This operation can be very annoyng when connection is slow. 

The suggested features aims to allow resuming, when the failed file is selected again. The uploading should continue automatically from there it stopped.
