Here is something to try to see if it fixes your problem.
Alter the maxRequestLength attribute in the httpRuntime element in your web.config file. It defaults to 4096. Change it to 10000 and see if that fixes your problem.


>I am creating crystal reports in ASP.net and converting them to pdf on the fly. All of this works fine until I have a very large, sql intensive query. This report will generate several hundred pages. My problem is that sometimes when the report reaches a certain size, a box appears in the browser asking me if I want to save the aspx file to my system instead of finishing the report. This ONLY happens on large reports. The process that I use to display the dynamic pdf is as follows:
>
>build the crystal report
>convert to pdf
>save to file system as strReport & ".pdf"
>and do the following
>
> Response.ClearContent()
> Response.ClearHeaders()
> Response.ContentType = "application/pdf"
> Response.WriteFile(strReport & ".pdf")
> Response.Expires = 0
> Response.Flush()
> Response.Close()
> System.IO.File.Delete(strReport & ".pdf")
