AJAX :: AsyncFileUpload Inside FormView Not Working?
Jul 25, 2010
I have a FormView inside a user control, and in the InsertItemTemplate, I have an AsyncFileUpload control, that I would like to to use. On the user side, it seems to work, but it doesn't work on the server side code behind. The HasFile Property is always false, and it doesn't fire the UploadCompleted event either. My UpdatePanel is in the master page.
<asp:FormView
ID="frmAddImage"
runat="server"
DataKeyNames="imageID"
DataSourceID="sqlImages"
Width="100%">
<InsertItemTemplate>
<cc1:AsyncFileUpload
runat="server"
ID="FileUploadImage"
Width="400px"
UploaderStyle="Traditional"
CompleteBackColor="Lime"
ErrorBackColor="Red"
onuploadedcomplete="AsyncFileUpload_UploadedComplete"
UploadingBackColor="#CCFFFF"
/>

Referring to the following: Ajax Asyncfileupload doesn't work as soon as I put it in a control I am having the same issue. I am not using a Master page though. I have an AsyncFileUpload control in a Panel, within an update panel.

i am getting some errors with my asyncFileUpload. I have a page with <formview><updatePanel><AsyncFileUpload>
when it is in ADD mode, the page works fine. Now I put it in EDIT MODE. I open the page and it works fine but as soon as i try to upload an image the nightmare starts. Debuggin I can arrive to these conclusions:
when I open the page for the first time, the sequence is: method load, AdFormView_ItemCreated (empty method), the Bind Process, AdFormView_DataBound.... Everything is ok. I click the button to upload and: AdFormView_ItemCreated, CONTROLSKIN(), Load, DataBound... but at this point controls are not recognized. The FormView has not been created.

I have built a custom Ajax User Control which uses the AsyncFileUpload control released with the latest Ajax Toolkit.
On my local machine the application works fine without error, however if I deploy the app onto my web server the functionality breaks.
I am trying to add a file via the AsyncFileUpload control, save it to the web server, then save some details into a datatable which is displayed in a gridview. All of this sits in an update panel.
When uploading small files (under 55kbs) the process works fine, however when uploading larger files, it doesn't like it. The control uploads the file successfully to it (the client error is not triggered), but it breaks when I try to save it to the web server. Upon saving, the document saves OK, but all the data is stripped away. It just saves the filename with no content. It looks like the AsyncFileUpload control has lost the File in session, therefore cannot save it. However the AsysncFileUpload.filename still exists and AsyncFileUpload.HasFile is returning true.
Has anyone seen anything like this before or have any ideas why this could be happening? I have set the web config httpRuntime maxRequestLength = 20480, so it shouldnt be that.
See code:

I have problem with AsyncFileUpload in CollapsiblePanel. In debug mode i have this error: "a._innerTB.style.width=a._inputFile.offsetWidth-107+"px"". I an begginer programmer and this is first time i see that kind of error. When AsyncFileUpload is outside the Panel or AsyncFileUpload everthing works perfect but i need this in AsyncFileUpload. Anyone know how to fix it? Or maybe there is another way to send file without reloading whole page (asp FIleUpload require reload)
<form id="form1" runat="server" enctype="multipart/form-data" method="post">
<ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</ajaxToolkit:ToolkitScriptManager>
<div>
<asp:Panel ID="PanelHeader" runat="server">
<asp:Label ID="Label" runat="server" />
</asp:Panel>
<asp:Panel ID="PanelBody" runat="server">
Example
<ajaxToolkit:AsyncFileUpload runat="server" ID="AsyncFileUpload1" UploaderStyle="Modern"
UploadingBackColor="#CCFFFF" />
</asp:Panel>
<ajaxToolkit:CollapsiblePanelExtender ID="CollapsiblePanelExtender1" runat="server"
TargetControlID="PanelBody" CollapseControlID="PanelHeader" ExpandControlID="PanelHeader"
Collapsed="true" TextLabelID="Label" CollapsedText="Open" ExpandedText="Close"
CollapsedSize="0">

i have made a page having AsyncFileUpload and Ajax calendar used both together on a page.
The page is not responding. displaying a runtime error. But when i am removing the Ajax calendar from page the page is working properly.
I need both controls on one page. below is my code:
html:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ajax.aspx.vb" Inherits="ajax" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>
<%@ Register assembly="System.Web.Ajax" namespace="System.Web.UI" tagprefix="asp" %>

AsyncFileUpload not working when .net app published to web server. It works fine in testing on my pc. I have checked security settings. I can get other upload scripts to work, but I wanted to try using the AJAX AsyncFileUpload. I thought maybe it's something on the server blocking it, but not errors, It just keeps saying "uploading" but it never finishes and it never uploads the file. Has anyone else had this happen?

i use a asyncfileupload control to upload files from my web pages. since i have a listview inside an update panel, and the listview needs to have the file upload functionality, i can not use a asp fileupload control.
the uploaded files are saved inside a temp folder in my application directory. i use a asp:button to upload files from the asyncfieupload control to my temp folder.
as long as i work on my local machine, the upload control inside the listview works perfectly fine, and does what is expected of it (i.e upload files :))
but when i move the code to my web server the asyncfileupload onthe page works just once, that is, it uploads just once (no matter whichever row of the listview it is) and for all other subsequent uploads, it uplaods a file of the same name to my temp folder but with 0KB size.
it beats me why asyncfileupload control would behave this way in the two environments.
could anyone suggest a possible reason/or something i m missing to configure on the server?

I have a Tabcontainer which contains formview1 in first tab and formview2 in second tab. I am not able to give Control based where Selectedvalue condition for formview2 datasource. I mean VS2008 is not picking it up automatically when I try to configure where condition. What should I have to do to make formview2 to make it working.

I am trying to use a tabContainer and two tabPanels inside a ItemTemplate of a Formview.
As soon I put them in the ItemTemplate I receive the following error on the formView control in design view:
"There was an error rendering the control. Could not find any resources appropriate for the specifie culture or the neutral culture. Make sure AjaxControlToolKit.Properties.Resources.NET4.Resources was correctly embedded or linked into assembly AjaxControlToolKit at compile time, or that all the satellite assemblies required are loadable and fully signed.
I have a scriptManager tag in the master page and an updatePanel in the content page.

These work if the textbox is not in formview. I have the textbox which is in the formview. I can't get dynDateTime() to get it working when my textbox is in formview control.

I'm trying to use a Tab control with 5 tabs inside a form view, when I view my aspx page in Visual Studio 2008 it displays a error message stating "There was an error rendering the control. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "AjaxControlToolkit.properties.Resources.resources" was coreectly embedded or linked into assembly ... " running the site just shows a blank page (as the control isn't rendered).
If I remove the tab control from within the ItemTemplate (or EditItemTemplate) and put it directly onto the page it works fine. Googling for the error suggests the references aren't correct, so I've reset the toolbox, and re-added the reference - this time referencing the file in my Bin folder (not the installation path of the Ajax Toolkit). Still it throws the same error. Finally I've stripped the code out into a page with the bare minimum (no code behind) and it still throws the same error. I'm sure I had this working previously. I'm using Visual Studio 2008 on Windows 7 and I'm using the 3.5 files from Codeplex (AjaxControlToolkit.Binary.NET35.zip) targetting .NET Framework 3.5.

This is my mistake: If I put an AJAX Editor INSIDE a FormView it loses the layout (I see all the icons button disordered and the Editor without background). If I simultaneously put an Editor inside a FormView and externally in the page both works fine and I see both in the right way. I repeat: with another Editor in the page the Editor inside the FormView works fine!!
I think it may depend on the css, so I have tried to modify the "DesignPanelCssPath" and the "DocumentCssPath" of the Editor inside the FormView, but nothing has changed.

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.
