Max request length File upload

[kalkumar]

Hi,

In order to handle the error i.e page cannot be dsplayed when we upload file size more than 4 mb using Fileupload control: Iam writing the following code in Global.asax file:

void Application_Error(object sender, EventArgs e)

{

// Code that runs when an unhandled error occurs

// Fires when an error occurs Check to see whether we came from the upload form

string fn=System.IO.Path.GetFileName(Request.Path).ToString();

if ( fn== "default.aspx")

{

//Get error details

System.Exception appException=Server.GetLastError();

HttpException checkException=(HttpException) appException;

//Verfy the expected error

int code = checkException.GetHttpCode();



if((code==500) ||(checkException.ErrorCode==-2147467259))

{


// Error 400 = bad request, user

// tried to upload a file that's too large

Session["ImageTooLarge"] = 1;

Server.ClearError();

//Go to the original target page

Response.Redirect("default.aspx");

}

}

and in the Default.aspx page load is like this:

if (!IsPostBack)

{



// Check to see whether we were redirected from the error page

int i=Convert.ToInt32(Session["ImageTooLarge"]);

if (i==1)

{

lblTooLarge.Text = "Exceeded";



}

but still I am getting page not displayed error. When I try to debugg the Application_Error event is firing in that event it is storing 1 into session, but the page is not redirecting to Default.aspx page.

What I am doing wrong.

Thanks in advance.

Have you tried using:

Server.Transfer("default.aspx");

Hi,
I tried the Server.transfer("Default.aspx") also but no use.

I believe there is a web.config/machine.config setting to adjust the max file size for uploaded files.

I would also suggest placing a try/catch block around the event to upload the file and handle it there instead of the global error.

there is also a file length property associated with the upload control. Depending on when the exception is thrown you may be able to check the file size. use an if/then/else statement to handel a file <= 4Mb.

Did you find the solution for this?

jmeckley...the file size isnt the problem, catching the error neither...its redirecting after the error occures to a custom page.
