I'm trying to get a page working using a tab container and multiple tabs. So, I created a new blank page and pointed it to my master page. The master page has two content panels within it.
I'm adding the tab container in the top conent holder, but when I go to view the page, I get an error. Below is the error followed by the code.
The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.

Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.

On a page we have Fileupload control. It's not inside UpdatePanel. We use it to display pictures uploaded by user. Everything works fine until we save the state (button click causes postback). User adds picture and then click save. After that if we pick the file and try to upload it on server then PostedFile equals null. I know that FileUpload doesn't save it's file inside ViewState due to security reasons, but all we want to be able to use again FileUpload to upload further files after postback and so far it's impossible.
