I would like to upload the selected files directly to the server without requiring the user to make a postback. The client side file upload should be followed by upload to server automatically. Also I dont want to use a Generic handler. How can I accomplish this?
One option is you can place a RadButton in the page and after all the files are client uploaded, you can invoke a click from the JavaScript and there by initiate postback so that the user does not need to click anywhere to generate a postback to upload the files.
RadAsyncUpload control does not provide such a feature out of the box to view the uploaded files. One option is you can populate all the uploaded files (file names) in a RadListBox and double click the items to view the file in a RadWindow. Please try the following full code I tried which works fine at my end.
