Preserving the file selection between page loads is limited by the browser due to possible security risks. While I am not familiar with all the implications that could have, one of them is that it becomes relatively easy for malicious sites to get the content of private files in one way or another.
As the file input field does not preserve its value, the same applies to the RadUpload
control, which utilizes file input fields for file upload handling.
That said, I want to note that RadUpload
does not contain specific code for clearing the file input field values.
I hope this helps.
