Hello,
I am exporting a PDF in code (not using the web viewer) and would like to prevent the user from interaction with the rest of the side until the Open/Save dialog prompt. Does anyone know if this can be done. And if so, how?
Thanks,
John

Hi John Stewart
Yes I can be done.
Can be used in Page_Load as
Yes I can be done.
/// <summary> | |
/ / / This method is used to provide a report to deliver a stream | |
/ / / Eg. Page.Response.OutputStream could be the recipient of this | |
/ / / Remember to set the mime type Page.Response.ContentType = "application / pdf"; | |
/// </summary> | |
/ / / <param Name="report"> Object containing the report you want to be saved </ param> | |
/ / / <param Name="output"> A stream containing the report as a PDF </ param> | |
public static void SaveReportAsPDF(Telerik.Reporting.Report report, Stream output) | |
{ | |
string mimeType; | |
string extension; | |
Encoding encoding; | |
var reportBytes = ReportProcessor.Render("PDF", report, null, out mimeType, out extension, out encoding); | |
output.Write(reportBytes, 0, reportBytes.Length); | |
} |
Can be used in Page_Load as
var report = new DokumenterRap (); / / Creates new report type document | |
Response.ContentType = "application / pdf"; / / Sets as pdf mimetype for IE to open the PDF file | |
ReportTools.SaveReportAsPDF (report, Response.OutputStream); / / Creates a stream of PDF repport | |
Response.Flush (); / / Provides the stream is flushed. |

Hello Janus,
My problem is not exporting the document. My problem is .... as the user is waiting for the report (which may sometime take 2-30 seconds) I don't want them to be able to interact with the website (click the export button again is my biggest concern). Perhaps I am mistaken, but I don't think what you offered will do that.
Thanks,
John

Hi John
I see. No the code is just for the Expert.
If you call a new page and the new page have to panels. one to make the PDF and one to show a text that state "pls. Wait for the PDF to be created this will take from 30 sekund to 3 min". In your code you store a session variabel to keep the info if this user has stated the PDF. Just store the time the PDF was started. I think that will do the job.
in the ASPx file put in this for one of the panel, and false for the panel with the text.
Hint: You can use the Modal="true"
