Parameter from session

[Arshad]

hello i added a reportviewer and from its properties set the report and a parameter, but the value for the parameter has to come from session variable, i want to achieve this by adding it in the reports.parameters, how do i set it.

i do not want to do it from codebehind.

Hello Arshad,

If you have set a report source to the ASP.NET ReportViewer, then you have noticed that the report parameters are not serialized in the resulting markup and therefore you cannot set their values declaratively. You can however do this quite easily with some code. As HttpContext is not available within the report expression context directly, you can use it from the calling application e.g.:

//Create a new instance of the Report1
Telerik.Reporting.Report report1 = new Report1();

//Gets the current user name from the CurrentUserName Session variable
string un = HttpContext.Current.Session["CurrentUserName"].ToString();

//Set a value to a Report Parameter1 used in a report filter
report1.ReportParameters["Parameter1"].Value = un;

//assign the report to a report viewer
InstanceReportSource irs = new InstanceReportSource();
irs.ReportDocument = report1;

ReportViewer1.ReportSource = irs;

All the best,
