I've faced a problem in a page where I've multiple tab. Each tab there is registration form and in the form there is a fileupload control. I'm using the updatepanel for each tab. For file upload I've used the postbacktrigger.Suppose I'm uploading file in the 3rd tab and submit button pressed It's always going back to the first tab. Is there any way to not going back to the first tab just stay which tab I'm using.
