How to reset RadAsyncUpload after submission in the code behind?

Question

I wonder how to reset (clear) RadAsyncUpload and leave the component as in the initial state

after the submission in the code behind?

my aspx ::

MultipleFileSelection="Disabled" InitialFileInputsCount="1" MaxFileInputsCount="1"
Width="100%" />

Try to add code below to Click event handler of submit button (not tested)

ScriptManager.RegisterStartupScript(this, this.GetType(), "clearUpload", String.Format("$find('{0}').deleteAllFileInputs()", rada_attach.ClientID), true);

`$find()` will return null in this case, as the control might not be ready on that state. Even `jQuery's $(document).ready()` will not help. Official support recommends to use a small timeout like `setTimeout(function () { $find('" + control.ClientID + "').deleteAllFileInputs(); }, 100);` to make sure, `$find()` will find the desired object.

You want to clear the list of items after Upload? if yes,according to this link you can do like this :

<script type="text/javascript">
   function clientFileUploaded(sender, args) {
       var count = sender._getRowCount();

       if (count > 2) {
           Array.removeAt(sender._uploadedFiles, 0);
           sender.deleteFileInputAt(0);
           sender.updateClientState();
       }
   }
