Is there a page event called when we use response.redirect to redirect to any other page? The reason is that i want to perform some actions just before the page is redirected.

Thx in advance

Then what is the issue? First perform the actions and then redirect the user to the desired page.

I am a bit apprehensive whether it will work or not.. Try it once..I wrote a code for a similar requirement and its working ....

u can call some events..

u will have create a different class

public void Init(HttpApplication context)
{
(IsDisposed)
{
throw (new ObjectDisposedException(this.ToString()));
}
else
{
context.BeginRequest +=new EventHandler(context_BeginRequest);
context.EndRequest += new EventHandler(context_EndRequest);
}
}

//This function will get called before ending exection of any page.
private void context_EndRequest(object sender, EventArgs e)
{
if (((HttpApplication)sender).Context.CurrentHandler.ToString() != "UR_PAGE_NAME")
{
//Ur Code
}
}

What is this IsDisposed, im getting error on it in vb.net. Also tell me who will set the value of the context and can I integrate it directly to the Page_Init event.

Hi All,

I need to accept a file from end user and convert it to pdf and after converting the file it should show a dialog box which has open, save and cancel button (the way we have while downloading a file).

If the end user say open then it should be embedded in IE and if the end user say save it then it should be saved on end users machine.

Please help me...

Thanks in advance...

Response.ContentType = "application/pdf";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + sFileName + ".pdf");
Response.BinaryWrite(urFileStream);
// or if u have byte[] u can use Response.OutputStream.Write(byteArray,0,byteArray.Length);
Response.End();

Hi Prateek,

Whatever file u r having u need to convert it to either in stream or in byte[] and then u can add it with Response... Everything else will be taken care...

Just check navneeth's post I guess there are some limitation on this kind of conversion. Here I am just changing the extension of file to .pdf but I dont know whether it will work with all kinds of files or not.....

What will be the file type ? You need to use some PDF conversion utilities to convert it to PDF.

What do you mean by embedded in IE ? AFAIK, you can't save the file to users system when they press save. You can redirect to that file and browser will allow user to download it. One question : File is uploaded from users omputer, and why again he needs to download it from server Confused | :confused:

Hi Navaneeth,

Thanks for the reply. File type can be any type of file ex: doc, xls, html or any other.

Also User can save it on server or not its his wish.

If user want to just view it then it should be opened in that browser itself and if he wants to save it then it should be saved on server.

If any other user can download/view the file.

I hope I made my self clear...

Thanks again...

But I don't think without using any PDF conversion utilities, you can't change a file to PDF.
