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.
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.
