File drag and drop is broken in MS Edge Creator's Edition. Reproducible in the following demo: http://demos.telerik.com/aspnet-ajax/asyncupload/examples/draganddrop/defaultcs.aspx
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).
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.
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.
There will be a validation that will stop dragged and dropped folders in the drop zone of RadAsyncUpload from being uploaded.
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.
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.
The RadAsyncUpload control is used on forms with other controls, and sometimes we need to validate the control, that is require that the user uploads a file before the form can be submitted. We have to use a Customvalidator and check the controls client-side properties to see if it has a file. But if you set the ControltoValidate property an exception occurs. Please support this property so that a radAsyncUpload control can be associated with an ASP.Net validator.
Upgrading to UI for ASP.NET AJAX Q2 2015 (2015.2.729.45) sets requestLimits maxAllowedContentLength in web.config to <requestLimits maxAllowedContentLength="0" /> <!--8MB Max upload--> resulting in errors like "PRM_ServerError" on postbacks.
We would like the ability to perform drag and drop upload when using the Silverlight module. We have found and have much support from forums and posts that the FileApi module does not work with environments with Windows Authentication and IE 11. This is due to a know IE bug that is not going to be fixed. http://www.telerik.com/forums/telerik-async-upload-fails-in-ie11-on-load-balancer http://www.telerik.com/forums/radasyncupload-freezes http://www.telerik.com/forums/ie11-freezes-when-is-used-async-upload Although I can disable the FileApi, doing so prevents us from using the much loved drag and drop.
