Hi Ravi,

I'm not quite sure what you mean by "add the event Asyncupload _Fileupload in the event of the button".
This event is fired for every uploaded file , which is about to be saved in the Target Folder, and in order to fire this event a post-back should occur. In the demo , which my colleague has pointed you to, there is no Target Folder , but the file is directly saved into database by extending the Handler and providing custom implementation. In general you could save your image along with other data using OnFileUploaded event , without implementing the case from the demo. You just subscribe on the above mention server event, and when you click a button which cause a post-back this event will be fired. When the event is fired you should get reference to the uploaded file:

protected void OnFileUploaded(object sender, FileUploadedEventArgs args)

{

UploadedFile file = args.File;

}

and then you could save it manually to the desired database. In this event you could also get reference to other controls like RadTextBox , but be aware that this event is fired for every file uploaded. So if you allow multiple file uploading you may end with data duplication, if you save data from other controls each time
event is fired.

I hope this would help you.

Hi Telerik,

How do you actually save files to the database when the OnClientFileUploaded() event is fired. I am fully aware of the OnFileUploaded() server-side event but I actually do not want to use it because I am also plugging a RadProgressArea along with it. Eventually, this results in the RadProgressArea to be shown twice (1st time while adding the files to the RadAsyncUpload control and the 2nd time when the upload button is actually clicked).

Basically, what I want to achieve is to save the files directly to the database and showing the RadProgressArea while getting rid of the Upload Button.

Cheers
