AJAX :: AsyncFileUpload In CollapsiblePanel Is Not Working?

Feb 14, 2010

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">
<asp:Panel ID="PanelHeader" runat="server">
<asp:Label ID="Label" runat="server" />
<asp:Panel ID="PanelBody" runat="server">
<ajaxToolkit:AsyncFileUpload runat="server" ID="AsyncFileUpload1" UploaderStyle="Modern"
UploadingBackColor="#CCFFFF" />
<ajaxToolkit:CollapsiblePanelExtender ID="CollapsiblePanelExtender1" runat="server"
TargetControlID="PanelBody" CollapseControlID="PanelHeader" ExpandControlID="PanelHeader"
Collapsed="true" TextLabelID="Label" CollapsedText="Open" ExpandedText="Close"

AJAX :: CollapsiblePanel Not Working In Latest Build?

Apr 21, 2010

I've had the lastest build in use for a while but only tried using a CollapsiblePanel yesterday and found it didn't work. No clues as to why not. The panels just stay open and images show as empty.

Just moved to ASP.Net 4.0 with VS2010. Is this the issue?

AJAX :: CollapsiblePanel Not Working In Multi Level Of Nested Gridview?

Aug 2, 2010

Ques 1. I am pasting only excerpts of my panel code (limited length here) within which I have 3 levels. The collapsible panel works fine till level 2 but when I am clicking on level 3 it shows for a second and collapses back to level 2. The collapsible doesnt work on panel pnlUserAccess below.

Ques 2. Can I make collapsible panel work on particular button click or image click?. As when I just put to to 2 levels I have to edit within the gridview and as soon as I click on the checkbox to edit the panel collapses.. I need to just give it a tree view style of appearance.

Ques 3. Can I also make the collapsible panel enable on read mode and disable on edit mode (if there is no possiblity for Ques 2)how to make it work. Just to be more specific on the code.

AJAX :: AsyncFileUpload Working Locally, But Not On IIS 6

Feb 3, 2010

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:

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.

AJAX :: AsyncFileUpload Not Working When .net App Published To Server?

Mar 9, 2010

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?

AJAX :: Asyncfileupload Control Not Working On Server?

Feb 19, 2010

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?

AJAX :: Validation Control Half Disappears In CollapsiblePanel

Aug 25, 2010

I have a textbox sitting at the bottom of a collapsible panel which has a RequiredFieldValidator sitting underneath that. If a user tries to submit the form without filling in this textbox then the RequiredFieldValidator generates a little "Required" box beneath the textbox. The trouble is that the panel doesn't resize propely and only the top of the validation warning box is visible so the message isn't legible.

I tried adding some margin-bottom to the div that contains the textbox and validator to ensure the space was already there but the moment the validation box appears the collapsible panel automatically resizes so the bottom of the panel meets the bottom of the textbox, ignoring the prior margin. Apart from moving the validation box, does anyone know how I can get the collapsible panel to resize correctly?

AsyncFileUpload RegisterClientScriptBlock Not Working?

Sep 3, 2010

I have a problem working with ScriptManager's RegisterClientScriptBlock which is not working.

I have a AsyncFileUpload and I want to preview the uploaded image dynamically after the upload.

the UploadedComplete is wired in Page_Init and here's the UloadedComplete block code in server side

void fileUpload_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
string csb = string.Empty;
string tempfolder = "picserver/posts/temp/" + Session["Username"] + "_" + DateTime.Today.ToString("yyyy_MM_d") + ".jpg";
string newfile = Server.MapPath(tempfolder);
Byte[] f = File.ReadAllBytes(newfile);
Imaging i = new Imaging();
i.ResizeImageFile(newfile, newfile, 64);
csb = "$("" + postImagePreview.ClientID + "").innerHTML = '<img src="" + tempfolder + "" alt="" />'";
System.Diagnostics.Debug.WriteLine("CSB: " + csb);
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "preview", csb, true);

and here's the html

<asp:Label ID="postImagePreview" runat="server" />
Upload a preview of your advertisement.
<asp:AsyncFileUpload ID="fileUpload" runat="server"
UploaderStyle="Traditional" UploadingBackColor="#CCFFFF" ThrobberID="myThrobber" />
<asp:Label runat="server" ID="myThrobber" style="display:none;" ></asp:Label>

here's my ScriptBlock

csb = "$("" + postImagePreview.ClientID + "").innerHTML = '<img src="" + tempfolder + "" alt="" />'";
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "preview", csb, true);

and it's not working.. even if I put "alert('hello');" in script parameter. still doesn't work.
