Ajax file upload: example needed

  

Hi

So far, I have built a MVC application that has a file upload form. The upload is done the "old" way, i.e. with a full postback.
Now, I wish to do the upload in the background using AJAX. There are a lot of samples for asp.net, but no for MVC.

Could someone give me an example of an upload form using AJAX in a MVC application?
How can I change my application to work with AJAX?

Thanks a lot for your help.

Connection time out + excel file upload + ajax async as a fix?

  

Thank you in advance for taking the time to read this.

I have a C# ASP.NET page that allows users to select 2 excel files from their machine and click a button to compare and look for differences.  Any difference is output to a gridview for them to review.  The code works brilliantly on my machine, on other machines inside our network, ect but when we try to access this page from outside the network and use excel file sizes around 1mb a piece, we're seeing a connection timed out error in IE (v6 and v7).

Due to limitations beyond my control, I can not save the files to the server first and then do my comparison code.  Instead I have to read the files to memory and am using a .dll found here, http://exceldatareader.codeplex.com/.  It basically reads the excel files into datasets, which are then passed on to my comparison method.

What appears to happen is that the comparison code takes some time, depending on the file size.  For example, 20kb Excel files net results with no errors in just a few seconds.  200kb files take longer but still succeed.  1mb files, though, get the connection timed out but only in IE and only outside our network.

So my thought was that perhaps the browser isn't getting the results back from the server fast enough and issues the connecti

file upload in chunks or not buffering in memory before writing to disk?

  

What are the options for handling file uploads to reduce the memory footprint?  Is there a way to upload in chunks?  Is there a way to stream upload directly to disk instead of loading entire file in server memory?

file upload in Create User Wizard Created User event with UpdatePanel Tag wont work?

  

Hi,

In my Create User Wizard1 Created User Wizard Event, I am collecting extra information from text boxes and allowing

I have put the Submit button within an Update Panel Tag but since I have done this it does not work.

Asp.Net upload file access denied

  

Hi,

I have the problem below, if anyone can help me, appreciate it.

Server Error in '/' Application.


Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path 'c:\Inetpub\EnewsAttFiles\employ-e-header2.jpg' is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Hig
