I need to upload a file (xml, pdf, etc) from the user's PC, but I need to write it directly to a file server. I cannot use FileUpload because there is no way to direct its initial upload to anything but the web server. So, how do I use the HTML INPUT to upload the file from the user's PC directly to a file server located at a different URL than the web server the web page is being hosted on?

My application allows a user to upload a file using the FileUpload control. The data contained in the uploaded file is then displayed to the user in a Grid for review if certain field validation criteria is met otherwise, a message is displayed stating that invalid data was encountered. If the data displayed is satisfactory, they have a 'Process Data' button to add the data to the system.
Initially, I used a simple If/Else block to determine if there was a file selected or not and if not, display a message to the user. As the coding got more complicated, this stopped working and I was told to use the RequiredFieldValidator control instead to get around the issues that arose.Now, I have a new issue: after the uploaded file data passes field criteria validation, the FileUpload box is cleared automatically and so when the user clicks the 'Process Data' button, the VC throws a message stating that the file name is missing from the FileUpload box.
I have a file upload control in which i want to restricr the users not to upload more than 1mb file. Is it possible using custom validator or any other code. I want to raise validation before any postback happends.

When a FileUpload is null then i want to set defualt file .

{
HttpPostedFile File = FileUpload1.PostedFile;

File.InputStream.Read(imgByte, 0, File.ContentLength);

<div class="container" runat="server">

View 1 RepliesIn my ASP.NET project, I want to add a facility to my page so that when the user clicks a button, a 'browse file' dialog box directly opens up. After he selects the file in the dialog box, I want to save that image on the server, and update an imagebox based on that selection.
Is there some sort of dynamic 'browse for file' type dialog box that I can use?
Edit Note: Actuall this is a suggestion related to WebPages and FileUpload Helper in Razor. I am not looking for workarounds. Following this tutorial: [URL] Under "Letting Users Upload Multiple Files" section it says : Because allowMoreFilesToBeAdded is set to true, the helper renders a link that lets user add more upload boxes. Now say you click "Add another file" link as shown and then decide not to upload 3rd file, is there a way to remove that third upload control?

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?
