I am facing a problem in FileUpload controls that is available inside update panel along with CalendarExtender.
Now When I click on submit button after browse a file it is returning null fileobject value in codebehind page.
[Code]....
I dont know what is the reason behind of this problem, can you let me know what is the cause and probable solution for this.
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...
<asp:UpdatePanel ID="Acc_UpdatePanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="acc" runat="server" style="position: inherit; height: auto;">
<div class="clear">
</div>
<div id="basic-accordian" style="border-radius: 4px;">
[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.
fileupload control is inside a grid, When Ajax is not used its s working correctly, so as wen i use a Update panel, am getting a error in uploading my file to thr database.

Inside gridview i am using the file upload control with update panel (ajax).
in save button file upload control null problem.
How to solve the issue.
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.

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.

The controls are added to the tab container but the button now causes a full page postback. The button_click event is no longer called. Is there something I am missing here.

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.
