The AsyncFileUpload control turns green, indicating that the attachment was successfully uploaded, but the designated method for handling the server side UploadedComplete event is never executed.

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
Page code -
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="act" %>
<act:ToolkitScriptManager runat="server" ID="ScriptManager1" />
<asp:UpdatePanel runat="server" ID="upnlFileUpload">
<ContentTemplate>
<asp:Button runat="server" ID="btnShowUpload" Text="Show Upload" />
<div runat="server" id="divUpload" visible="false">

I have the asyncFileUpload control inside a user control which is a wizard control step. The wizard control is inside a AJAX update panel.
I have a requirement to save the complete folder path along with the file name when user selects a file in the asyncFileUpload control. In order to achieve this on the server side UploadedComplete even I save the PostedFile.FileName to a session variable.
Then on the client side OnClientUploadComplete I force a postback for the UpdatePanel. In the postback I get session variable value and then do my processing.
server side upload completed event when I save the posted file name to a session variable. This is working in my local machine. I am able to retrieve the Session variable on the postback, but when I move the code to my test server the Session value is coming out as blank. I validated that the UploadedComplete event is triggered on the server, but for some reason the Session value is blank.way I can get the PostedFile name (complete path) on the Client side?
I'm new to ASP.NET AJAX AsyncFileUpload so I've created an aspx page to test it but it seems there's some bug with that control because the server side UploadedComplete event does not fire.
the aspx :
<form id="form1" runat="server" method="post" enctype="multipart/form-data">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager> [code]....
I cannot get the asyncfileupload to fire the uploadcomplete event at all.
I did a test:Protected Sub AsyncFileUpload1_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles AsyncFileUpload1.UploadedComplete
I have the following code in Page_Init (actually in a function called by Page_Init in response to a __doPostBack call)
System.Web.UI.WebControls.DropDownList ddlGroup = new System.Web.UI.WebControls.DropDownList();
rowString = rowNumber.ToString();
Anyone know why RegisterStartupScript won't work in the UploadedComplete event? It used to work just fine, but in version 40412, it doesn't do anything.
I had started another thread called 'AsyncFileUpload Broken??!!??', before I realised what was causing the problem. Now that I have found the culprit, I thought a new thread is needed on this issue alone.
I have been using the asyncfileupload control and have everything working nicely with it when uploading. However, also on my page the user can download a file.
If the following path is taken the asyncfileupload does not behave correctly:
1: Download a file
2: Attempt to upload a file via the asyncfileupload
When the user attempts the upload, the previous event is fired, which causes the download to fire again and the asyncfileupload freezes.I'm not sure why this is happening but I think it's to do with the response.end of the download and the
asyncfileupload/toolkitscriptmanager.
I have a DropDownList that fires off some server-side databinding in its OnSelectedIndexChanged event.
<asp:DropDownList ID="ddlGroup" runat="server"
AutoPostBack="True" OnSelectedIndexChanged="SelectGroup" />
Elsewhere in the page, some JavaScript opens a popup. When the popup is filled out and submitted, I want to use JavaScript to fire that OnSelectedIndexChanged event in the opener page. I found some other code that does something similar:
if (window.opener != null ) {
var cf = window.opener.document.forms['aspnetForm'];
if (!cf) {
cf = window.opener.document.aspnetForm;

I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.
I would like to call the click event of the the AsyncFileUpload control programmatically, is it possible? I tried to call the click event, but it is not working. actually I don't like the appearance of the upload, so I am trying to hide the AsyncFileUpload control, assign the file name and click it programmatically.
View 2 RepliesI have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.
View 3 RepliesI have two controls, each placed in their own <div> and <UpdatePanel> on my form. I am having trouble getting the partial page postback to fire after the file upload has completed. I have not used the __doPostBack approach before so I'm not sure if I am heading in the right direction.

On my webform I have an AsyncFileUpload control. At first it is set not to be visible until two textboxes are filled. On the textbox_textchanged events the uploadcontrol is made visible. At that time the UploadedFileError event is fired.... why? The control is empty, so there is nothing to upload, but apparently it still tries to.How can I fix this?

View 1 RepliesHow can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?
I only want it to fire when a particular value is chosen in the list.
I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.
I have my ReorderList setup, and it seems to work. It doesn't give me any errors, and it allows drag/drop of the entries.
BUT, it never updates my datasource. I have tried putting breakpoints on the update events, both on the reorder list, but also on the datasource, none fires.
What could i possibly do wrong, to achieve this?

I need a Slider that will only postback when the slider has been moved. Can this be achieved with SliderExtender?
I have a TextBox with autopostback=true, within an updatepanel within a usercontrol. The TextBox is extended by SliderExtender (default settings).
The TextBox's TextChanged event fires perfectly when the slider is moved (MouseUp - standard extender setting). The aspx page is partially posted back, and all is well.
However, if another usercontrol on the same aspx page causes a partial postback, the SliderExtender causes the TextChanged event to be raised - for no aparent reason. This is causing problems.
Is it possible to prevent postback unless the slider has actually been moved?!
