Hello Everybody,

I have used Response.Flush() with Response.End() to download file in my application .But when some body downloads the file (execution of Response.Flush)
ends the connection between client side(.aspx) and server side(.cs).My problem is i am refreshing the page from .aspx by "http-equiv=Refresh" to redirect to another page.

Since there is no connection in between client side and server side,no redirection happens..

Can anybody have any idea how to download the file(from dataset to some customized loacl path) with out breaking the connection between the server side and client side..

Appreciate your HELP!!!

Cheers,

Sugato

if (ds.Tables[0].Rows.Count != 0)
            {
                for (i = 0; i < ds.Tables[0].Rows.Count; i++)
