Hello Napa,

It seems that you try to invoke a modal dialog on the server. Check out Report printing from web without ReportViewer forum thread that elaborates how to invoke a print operation on the client.

This is the code i am using in report.

BCRSeq = (

string)Session["BCRseq"];

 

fiscalYear = (

string)Session["FYear"];

 

reportDocument =

new PrintReport(BCRSeq, fiscalYear);

 

 

this.ReportViewer1.ViewMode = ViewMode.PrintPreview;

 

 

this.ReportViewer1.Report = reportDocument;
