RadAsyncUpload does not upload files in iOS 8 Safari. After selecting a file/files for upload, their upload remains as pending and never reaches the end of the process.
Note: there is a known iOS 8 Safari issue with <input type="file" />

when files are deleted via the user interface, this "frees up" the max file count for additional files to be uploaded. When files are deleted via API, the deleted files are still counted against the maxfilecount, and are not "freed up"

to reproduce:
run the attached web form.
do not select "delete via api" checkbox
add and remove a number of files.
good.

reload.
do not select "delete via api"
upload file A
select "delete via api"
upload file A one more time (note it will be deleted via api before it actually gets uploaded)
deselect "delete via api"
upload file B
note you can no longer upload files, allthough only 2 have been uploaded and maxfilecoutn is 3
bad.

when deleting files from radasyncupload via the "built-in" delete button, both the upload_removing and upload_removed events are fired. However, when deleting files via the api, only the uploadRemoved event is fired.

to reproduce: 
1. run attached web form. select file for upload. click remove button. view console. note console entries have text "filename in UPloadRemoving.." as well as "filename in UploadRemoved...". Good

2. click the "delete via api" checkbox to enable. select another file. view console. Note console entry only has text "filename in UploadRemoved..." bad.

when deleting files from radasyncupload via the "built-in" delete button, "get_fileName()" method in both the upload_removing and upload_removed events returns correct data. However, when deleting files via the api, the get_fileName() method returns bad content.

built-in button something like:
document.pdf

api something like:
document.pdf<span class="ruFileProgressWrap"><span class="ruFileProgress"></span></span>

to reproduce: 
1. run attached web form. select file for upload. click remove button. view console. all good.

2. click the "delete via api" checkbox to enable. select another file. view console. bad.

Hi,

When we upload files using RadAsyncUpload control, will get the uploaded file along with the two images.
1. check image
2. cross image (to delete the uploaded file)

my question is can we overwrite these images in our  application.

The MaxFileSize property is an int - this means a limit over 2GB can't be set. Please change this property to a long. 

RadAsyncUpload throws a javascript error:

SCRIPT16389: System.NullReferenceException: Object reference not set to an instance of an object.
   at System.Windows.Browser.ManagedObjectInfo.Invoke(ManagedObject obj, InvokeType invokeType, String memberName, ScriptParam[] args)
   at System.Windows.Hosting.ManagedHost.InvokeScriptableMember(IntPtr pHandle, Int32 nMemberID, Int32 nInvokeType, Int32 nArgCount, ScriptParam[] pArgs, ScriptParam& pResult, ExceptionInfo& pExcepInfo) 

when Silverlight module is used and uploading is canceled.

Hi Telerik Team,
is it possible to implement the feature into the uploadmodule control , that you can open the uploaded files per Double-Click.
We want to use the control to create offers and we want to give the users the option to upload files - that works wonderful.
But the following editors of the offers don`t have the chance to open the "attached" files.

Thank you very much.
Best Regards,

Jan Brandenburger

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.
