How to Upload big file size in asp.net ?
I have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:

And this is the code behind:

I'm a beginner i work with visual studio 2005 and ajax 1.0
i have a web page with a control input i must to check the weight of the file but in javascript WITHOUT ActiveXObject !?
i use these code to set limit size for image that users want to upload
protected void BtnUploadS_Click(object sender, EventArgs e)
{
string path = Server.MapPath(".") + "../image/House";
[Code]....

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?

I want to check the selected file size BEFORE uploading a file with the asp fileupload component.I can not use activex because the solution have to works on each browser (firefox, Chrome, etc..)How can I do that ?
View 3 RepliesSo we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.

When I upload small sized tiff file(approx. 800KB) in my website folder on local system through fileupload control in asp.net. It uploads the file successfully. But when I upload 5MB or more in size tiff file. It can't upload file and display the following message.Internet Explorer cannot display the webpage.Here is my code:
if (FileUpload1.HasFile)
{
string filename = FileUpload1.PostedFile.FileName.ToString();

Is there any way to change the look of the FileUpload control, in particular I just want to make the input field bigger but nothing obvious seemed to work.

I am trying to increase the size of file upload for my ASP.NET app.. (Windows 2008 Enterprise + IIS 7)
What I have done in web.config:
<system.webServer>
<security>
<requestFiltering allowDoubleEscaping="true">
<requestLimits maxAllowedContentLength="100000000" />
</requestFiltering>
</security>
</system.webServer>
I have made a cms where images can be uploaded. Now I have a problem that my images need to resize (in right proportion) depending on the screensize.
View 3 RepliesMy requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.

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?
