There will be a validation that will stop dragged and dropped folders in the drop zone of RadAsyncUpload from being uploaded.
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.
We use the RadAsyncUpload control in several places in our application. We would like to be able to style the upload button to match other buttons on the form. Our preference would be to apply a CSS style but if the only option is to apply an 'skin', that would be acceptable.
Workaround: Set DisablePlugins="true" or set RenderMode="Lightweight"
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).
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.
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.
