Calling other Methods after Downloading a file

Question

Hello Friends.

I'm using the following code in my app to download a .wav file.
This all code is on MySpace.aspx page. When Request made on this page a method works there getData(); which simply fetch the records.

There are Three other methods

1. trackCount() == this checks the count only
2. MessageRead() == this marks the flag as R in the database;
3. getData() == this fetch the records and check if flag is U then change the row color in Gridview.

In the code I have used

C#

Response.Redirect("MySpace.aspx?val=Inbox", false);

What I want to do simply download the file if download done the flag updated to R and getData() method to call so that the color of row in gridview changes as per the flag.

But if I use getData(); then it doesn't reload after the file downloaded.
And If I make

C#

Response.Redirect("MySpace.aspx?val=Inbox", false);

then gridview reloaded and row color changes but file doesn't get downalod.

Please suggest me how can I accomplish this. Basically I want to call getData() method after Response.Write() method.
I removed Response.End() because this was terminating the Request and as I require I have to call some other methods after downloading the file.

Following is the Code.

C#

Response.AddHeader("content-disposition", "attachment; filename=" + info.Name);
Response.AddHeader("content-length", info.Length.ToString());
Response.ContentType = "audio/x-wav";
Response.WriteFile(info.FullName);
doflag = true;
if (doflag)
{
trackCount("INSERT INTO TrackUserAction(Phnum,trackdownload) VALUES('" + Session["phnum"].ToString() + "',1)", "in");
                           MessageRead(((Label)gvMyDetails.Rows[index].FindControl("lblSender")).Text.Trim(),((Label)gvMyDetails.Rows[index].FindControl("lblMsgTime")).Text.Trim(), msgID);
Response.Redirect("MySpace.aspx?val=Inbox", false);
}

Thanks and Regards

Hi, Manish

If u are try to download a file from ur local server or from webserver
u need to convert the file into byte and than try to read that

Here the sample Code:

C#

Public Void DownloadFile(string Path)
{
 long FileSize;
 FileInfo fileName = new FileInfo(path);
 Response.ContentType = "audio/x-wav";
 Response.AddHeader("content-disposition", "attachment; filename=" +                        fileName.Name);
 FileStream sourceFile = new FileStream(path, FileMode.Open);
 FileSize = sourceFile.Length;
 byte[] getContent = new byte[(int)FileSize];
 sourceFile.Read(getContent, 0, (int)sourceFile.Length);
 sourceFile.Close();
 Response.BinaryWrite(getContent);
 //Response.Flush();
 //Response.Close();
 Response.End();
}

If Response.End() throws an exception than use Commented Code.
Here u need to pass the path to this method than it will download.

Hope it will help u....

Sabbi..
