I am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}
but how to access the content type of the file selected by user.

Now I have an File upload control outside panel through which I have to attach a file and send it in mail along with the already attached panel. But I am unable to figure out how to do it.
View 1 RepliesI have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
View 4 RepliesI'm trying to combine nested listviews, updatepanel and asyncfileupload, but have run into some problems. I'm having a main listview listing some projects, and in each project I have a nested listview listing some images in that project. I also have an insertitemtemplate, for inserting new images. This template contains an asyncfileupload control. Everthing is contained in one large UpdatePanel, to enable smooth editing of the images and their associated information.
Problem 1:
The fileupload is complete now, and the file uploads as I expect. In the AsyncUploadCompleted event I'm also inserting the uploaded image to the database. So far so good. But when the upload is done, I want to be able to see the newly updated record in my nested listview. But this is not the case. I'm not able to DataBind the listview in the AsyncUploadCompleted, because that throws an exception saying "The control collection cannot be modified....". So, how do I manage to do an async update of the nested listview, showing the new record?
Problem 2:
When deleting items from my nested listview, after the async update the listview shows up without any items except the InsertItem. The items are not removed, a refresh of the page brings them back. Why is the databinding lost during the async postback?
I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
I have a async file upload control.What I want is when the file is loading on the server I want show a progress message "Loading...." not the default image in async file upload and disable the upload button during this period. Sometimes when the file size is large it takes time to load the file on the server and in between user may click the upload button where the file is not loaded on the server yet.
View 2 RepliesHow to set default file in <asp:FileUpload />
When a FileUpload is null then i want to set defualt file .
regarding my code :
Byte[] imgByte = null;
if (FileUpload1.HasFile && FileUpload1.PostedFile != null)
{
HttpPostedFile File = FileUpload1.PostedFile;
imgByte = new Byte[File.ContentLength];
File.InputStream.Read(imgByte, 0, File.ContentLength);
}
I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e)
{
const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb
if (Request.ContentLength > maxFileSize)
{
Response.Redirect("~/FileUploadError.aspx");
}
}
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?

View 1 RepliesI have an Async File Uploader control inside a Repeater which is inside an update panel. Now,I am uploading the file into ftp,so I am not uploading the video file,using SaveAs() method. For uploading the file in ftp,I have this UploadFile method which takes these four parameter:FileName, UploadPath, FTPUser, FTPPassword.Now this FileName,I have to send the full file path. My UploadComplete event looks like this:
<pre lang="cs">protected void AsyncVideoUpload_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{//VideoPath is a session variable
VideoPath = string.Empty;
if (AsyncVideoUpload.HasFile)
{
// string filepath = AsyncVideoUpload.PostedFile.FileName;
string filepath = e.filename;//above two captures only the file name,but I want the total path,like c:/MyDocuments/...
UploadFile(filepath, "ftp://172.20.117.102","test","Value*12");
VideoPath = AsyncVideoUpload.PostedFile.FileName;
}

I want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

View 3 Repliesi am trying to upload files through the ASP.NET File Upload control.
Every thing is working fine, except for the fact that when i try to upload the file on the server i am getting an error: (probably some authorization exception).
do i need to give some rights to the upload up there on the server. If so then for which account and do i need to restart the server after giving rights?
