Hello,
I have a scenario where I need to pass a session varable value to a report in a reportbook on a html page. I haven't been able to find any code for this in the forums or figured it out by my self.
Depending on who's logging in to my reportpages different report results will appear. I store the users id in a sessionvariable on loggin. I've found a solution for a single report but not when I want to put the report in a reportbook.

I'm thankful for any directions and/or codesamples.

Best regards

Janne

Hi Jan,

You can access any object in the report through its API. Here is a sample code:

Telerik.Reporting.IReportDocument mybook = new ReportBookCL.MyReportBook();
List<Report> reports = new System.Collections.Generic.List<Report>(mybook.Reports);
reports[0].ReportParameters[0].Value = <value_from_session_var>;
ReportViewer1.Report = mybook;

Note that in the snippet above we use a class inheriting ReportBookControl named ReportBookCL.MyReportBook. If you create your book at runtime you should use: Telerik.Reporting.IReportDocument mybook = this.ReportBook;

Best wishes,

Hello Steve!

Thanks for your as always quick reply!
The parameter gets passed ok now but there's only one of two reports that
show up in the reportbook.

Thank you!

Here's my code:
    protected void Page_Load(object sender, EventArgs e)  
    {  
        if (Page.Request.Cookies["kundIdNr"].Value.ToString() != "")  
        {  
            Telerik.Reporting.IReportDocument mybook = this.ReportBookControl1;  
            System.Collections.Generic.List<Telerik.Reporting.Report> reports = new System.Collections.Generic.List<Telerik.Reporting.Report>(mybook.Reports);  
            reports[0].ReportParameters[2].Value = Page.Request.Cookies["kundIdNr"].Value.ToString();  
            ReportViewer1.Report = mybook;  
        }  
 
 
        else  
        {  
            Response.Write("Någonting gick fel. Din browser kanske inte stödjer cookies.");  
        }  
}  
 
 
 
<form id="form1" runat="server">  
    <div> 
       
        <telerik:ReportViewer ID="ReportViewer1" runat="server" > 
        </telerik:ReportViewer> 
        
        <telerik:ReportBookControl ID="ReportBookControl1" runat="server">  
            <Reports> 
                 <telerik:ReportInfo Report="rapport1.kostperaktvtyp, rapport1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">  
                </telerik:ReportInfo>                 
                <telerik:ReportInfo Report="rapport1.kostperps, rapport1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null">  
                </telerik:ReportInfo><%----%>   
            </Reports> 
        </telerik:ReportBookControl> 
      
    </div> 
    </form>

what I did wrong. But thats of less importance right now :-)
