Fileupload Within Update Panel / Can't Get The FileUpload Working Properly

Jan 15, 2010

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:


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.

AJAX :: Use A Fileupload Control Inside An Update Panel

Apr 5, 2010

Having a bit of trouble here. I know that if you want to use a fileupload control inside an AJAX update panel then you need to create a trigger for the control that performs the uploading postback to the updatepanel, but the problem is, I have an update panel that contains web usercontrols. I therefore can't add a trigger to the control(FileUpload) directly because it exists in the web control.

AJAX :: Update Panel - Asp Panel Not Working Properly

Jun 8, 2010

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.

I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.

When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.

I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

Ajax Update Panel Not Working In Facebook Iframe?

Jan 27, 2011

I have a facebook app with an asp.net update panel. It works fine when running outside facebook, how ever once I run the app in Facebook the update panel stops working. I check the javascript console and found the following errors were occuring.

Uncaught Sys.WebForms.PageRequestManagerParserErrorException: Sys.WebForms.PageRequestManagerParserErrorException

The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
