View 4 RepliesIn 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;">

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.
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.

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.

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.
View 2 RepliesI am using .net 3.5 framework. I have a Tabcontainer inside that I have place asp.net fileupload control which is inside update panel. It's been known fact that fileupload control does not work under update panel unless we use Postback Triggers.

I am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.
Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?
I have, within the update panel, a report viewer control, a textbox for parameter input and a button to show the report in report viewer control . When i click on the show report button I got the following javascript error and didn't get report called:
Errors :
1. this_client_Controller is null or not a object
2. parent.document.getElementById(...). Client Controller is null or not a object
I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.
The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.
I have formview , there is save linkbutton & upload control, same for insert template & edititem template. both save butons have name 'LnkSave'. without update panel it is working. but with panel not. i used trigger for control but it gives error like ' already definition for LnkSave button' . i changed name of save button in edit item template, yet it's not working.

View 2 RepliesI'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.

View 5 RepliesI'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.
It works but incredibly slow and whats more on the FF I have the given error:
The state information is invalid for this page and might be corrupted
3 checkboxes with other fields are in the updatePanel
Each field is in dl tag with runat="server>
I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.
Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)
If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.
Oh and I'm using ASP.Net and cant upgrade on this project.

I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.

I've left out some of the middle code of there is alot.
I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'.
When the button is clicked code similar to the following is executed:
If FileUploadControl.HasFile Then
'Save the file and do some other stuff
End If
This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?
I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.
I'm working on a simple demo project so that I can learn some things about ASP.NET's AJAX capabilities. My problem is that I can't seem to get an UpdatePanel to work properly with a CheckBox inside of it. Here is the markup I'm using in my .aspx file:

I am using JQuery tabs in my aspx page, but update panel is not working. If I do any operation in tab2, after posting back, tab1 is activated.
