Hi, I am using the following code.
I tested the application with this code on some other machines it works fine but on some machines it throws error which I described in my previous post ( File corrupts).
What might be the reason for this

protected void btnExportToPdf_Click(object sender, EventArgs e)

{

isPdfExport =

true;

dgDocReport.ExportSettings.ExportOnlyData =

false;

dgDocReport.ExportSettings.Pdf.PageWidth = 2000;

dgDocReport.MasterTableView.ExportToPdf();

}

and my source is as follws

<Pdf Author="Anonymous" Title="RadGrid export" Subject="RadGrid Export" Keywords="None"

AllowCopy="True" AllowModify="True" PageTopMargin="1in" PageBottomMargin="1in"

PageLeftMargin="0.2in" PageRightMargin="0.2in"></Pdf>

</ExportSettings>

and one more thing if grid contains no data I am displaying the grid with grid contains no data text, this as well is not exporting to pdf.

Hello Ram,

This behavior was already fixed by our developers.
I suggest you download the latest internal build from the following link:
Latest internal builds

Regarding the previous question: I'm afraid that the code-snippet you shared below is not enough for me to provide straight-to-the-point answer. I strongly recommend you isolate the problem in a simplified working project and attach it to a support ticket to be debugged locally.

Hi,

I have one more question

My dll is in GAC, So Do I need to completely uninstall the older version and install the new hot fix.

because I tried by uninsatlling older version and insatalling new one the application works fine.

And when I have the both the version in GAC and in one of my webform I am refering old one and in other I am refering old one and both pages are having radgrid control, So when I try to compile the application I am getting follwing error that

radgrid containg in both the versions

So here my question is can I have both the versions in GAC and can I use them in one apllication

Thanks,

Daniel,

I have exactly the same error message, in both IE6 and IE7. I have downloaded the latest Telerik.Web.UI.dll (2009.1.402.20) and applied it, but the same error still occurs. (The new DLL is definitely being used, because the grid style has changed noticeably.)

To reiterate, I have an ASP.NET AJAX RadGrid and am executing ExportToPdf() on a button click. I am prompted to Save or Open the document. If I click Open, then Adobe Reader opens but displays the error message:
"There was an error opening this document. This file cannot be found"

Interestingly, if I choose to Save the document instead, then I can open it fine.

Thanks,
Jo.

p.s. I am using Adobe Reader 8.1.4 with IE7 and 8.1.2 with IE6.
My colleague says it works okay for him with AR 7.1.0 and IE7.
And it fails for him with AR 7.0.8 and IE6.
But we cannot assume that every web user has AR 7.1.0.

Daniel,

Apologies for the delay in replying. By trying to create a simple demonstration website for you, I have narrowed down the problem.

On Page_Load, we call this method:

        /// <summary>
       /// Prevents a page being cached on the Client
       /// </summary>
       /// <param name="p_response">The Http Response for the page</param>
        public static void DisableCaching(HttpResponse p_response) {
           p_response.Expires = -1000;
           p_response.AddHeader("pragma","no-cache");
           p_response.AddHeader("cache-control", "private");
           p_response.CacheControl = "no-cache";
       }

If I comment out the last line, then the ExportToPdf() method works fine. But I don't really want to remove this line permanently. Do you know of any configuration setting for the RadGrid that I can make that will have the same effect?

Thanks,
John.

Hello John,

We tried to reproduce the problem using Adobe Reader 8.1.4 and Internet Explorer 7 but unfortunately without avail.

We performed three tests total:
Windows XP / Internet Explorer 7
Windows Vista x86 / Internet Explorer 7
Windows XP / Internet Explorer 8

I'm not sure how to recreate your scenario completely. Please provide more details on your OS/browser version.

Kind regards,
