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. <% ... %>).

I want to uplaod my images into the database.it works fine if my images are inserted into the database on postback,but when i put my FileUpload control in UpdatePanel the FileUpload.PostedFile property shows NULL.remember my scriptmanager tag is in master page.
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.
In my WebForm I hv used an accordion and this accordion is in an UpdatePanel with UpdateMode="Conditional" .
In that accrdion , in last pane i hv a fileupload - when i select a file and click upload button then always the fileupload control has no file and it returns false everytime .
I have written trigger in UpdatePanel also still it doesn't work. Without updatepanel fileupload control works properly, this problem arise after i use UpdatePanel...
[URL] .... I am referring to the link given mentioned above, i want to save image details into database of each file, if i select two files i want to save filename in database in each row. ist file in 1 row , second file in next row with file name.

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.
i have searched on google and got an article [URL] keep selected file in fileupload control even after page postback. But it's not working at all. So is there any way through which we can keep selected files in fileupload even after page postback.?
I have a page with 2 separate UpdatePanels which are supposed to load and post back independently. But I can't get the UpdateProgress templates to show on page load.
<%@ Page Language="C#" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> runat="server"> <script protected void Page_Init(object sender, EventArgs e)
I have a problem where the collapsible panel extender stops behaving properly after the first row in the gridview. On row 2, the collapsible panel don't work anymore (the label is not clickable). It gets even worse on row 3 where the product category accordion pane doesn't open anymore. This is the structure:
Accordion AccordionPane: General Info Formview AccordionPane: Product Categories Gridview 3 boundfield 1 templatefield CollapsiblePanel 1 templatefield 3 collapsiblePanel
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.
so what did i do wrong with the regex that its now allowing other document types to be uploaded. I need to make sure that ONLY pdf are allowed. What can i change to the validator and if anything add to the code behind to correct this?
