    I am using RadAsyncUpload.

    I would like to select a file via "browse" from the input, perform a preview which that does some pre-processing and validation.I then return information to the user regarding the validity of the upload file. If the end users wishes too, they should just be able simply press another button which writes the changes. I noticed that after a file is uploaded even though the name persists in the input, performing and upload again does not do anything. Is there a way to achieve this behavior?

    Hello Richard,

    You can implement custom HttpHandler that does the validation then returns validation information to the client. After that, if the validation is success the customer can post the page to the server and RadAsyncUpload will process the file. Otherwise you can remove the file from the async upload.
