We have what we believe followed the instruction for wiring a Telerik report to a data table but cannot get it to run.
The report has it's own class lib and the actual method to call it is in a .net website here is the calling code which produces the datatable with no issues

The source of the report definition has not been specified.

this tool is most frustrating to use...any guidance appreciated

Web interface code

   protected void Run_Click(object sender, EventArgs e)
{
    Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
    objectDataSource.DataSource = GetData();  
    var report = new CallCenterReportLibrary.CSRPerformance();
    report.DataSource = objectDataSource;

    //Pass to viewer
    var instanceReportSource = new Telerik.Reporting.InstanceReportSource();
    instanceReportSource.ReportDocument = report;
    this.ReportViewer1.ReportSource = instanceReportSource;

    ReportViewer1.RefreshReport();
}

private DataTable GetData()
{
    ReportBO objReportBO = new ReportBO();
    ReportBLL objReportBLL = new ReportBLL();

    //Campaigns
    var campaignCollection = ddlCampaign.CheckedItems;
    var campaignList = new StringBuilder();
    foreach (var item in campaignCollection)
    {
        if (item.Checked)
        {
            campaignList.Append(item.Value + ",");
        }
    }

    //Teams
    var teamCollection = ddlTeam.CheckedItems;
    var teamList = new StringBuilder();
    foreach (var item in teamCollection)
    {
        if (item.Checked)
        {
            teamList.Append(item.Value + ",");
        }
    }

    //Agents
    var agentCollection = ddlAgent.CheckedItems;
    var agentList = new StringBuilder();
    foreach (var item in agentCollection)
    {
        if (item.Checked)
        {
            agentList.Append(item.Value + ",");
        }
    }
    objReportBO.StartDate = DateTime.Parse(txtStartDate.SelectedDate.ToString());
    objReportBO.EndDate = DateTime.Parse(txtEndDate.SelectedDate.ToString());
    objReportBO.CampaignId = String.IsNullOrEmpty(campaignList.ToString().TrimEnd(','))== true ? null : campaignList.ToString().TrimEnd(',');
    objReportBO.TeamId = String.IsNullOrEmpty(teamList.ToString().TrimEnd(',')) == true ? null : teamList.ToString().TrimEnd(',');
    objReportBO.AgentId = String.IsNullOrEmpty(agentList.ToString().TrimEnd(',')) == true ? null : agentList.ToString().TrimEnd(',');

    return objReportBLL.LoadCSRPerformanceData(objReportBO);;

Hi! 
What I try to achieve, is to get a Word document with report containing multiple, generic tables.
Let me just go straight to whats wrong:
If for example i generate three tables, which are small enough to fit on one page, everything is fine as on screenshot below:
Small tables OK

But in situation, when table have more rows and it's size exceeds size of a page, strange things happens, blank pages are added and so on:
Big tables - problems screenshot

All i do, is generate tables from code (as many tables as many data I have), then generate one big table with one column and as many rows as tables I've created, and put them inside each row. Then I add this big table to detail section. Playing with properties as keepTogether etc. did not help. Do You have any advice or ideas what could be wrong and how to deal with such problem?

Sincerely,
Bartek

hi,
My target is to create report at run time.No configuration at design time.I follow the following link
http://www.telerik.com/help/reporting/object-data-source-how-to-bind-to-data-table.html
which is for windows application.I add the same code in a web application project.But the report shows empty.

Why this code is not working in web application?Any suggestion?Please let me know.

Somehow, I have spent two days trying to figure out how to do something that should be so simple.  I am using Telerik Reporting Q3 2010.  I have a data source that contains a Boolean value called IsLaborCost, a String Value called CategoryName and a decimal value for CostAmount.  I simple want my table to list the Categories that IsLaborCost is true, then a subtotal, then list the ones where IsLaborCost is false and a subtotal, and then a grand total.

I have tried adding a group and using the IsLaborCost as the Group By, but then it only shows the first category from the group.  I cannot add a child group to that to set it to just show the details.  If I add my initial group and select the Details option, then it shows all of my categories, but they are not grouped where I can add subtotals and such.  What am I missing.  I have read the documentation and played with the samples but cannot seem to get mine to work right.

I have built and deployed the reporting app to the local IIS 7 using the File System method. I have launched and tested the web site and the reporting and all works well.

When I FTP the site to a public server (Arvixe) I get a runtime error. Both the reporting DLLs have been deployed and the web site files and structure are identical. I suspect it may be in the web config which is minimal. Do you have any suggestions

hi Telerik Team,
 

I just upgraded to the Q2 2013 DLLs for reporting and find that the Telerik.Reporting.Report.ReportParameters Value property is not updated when the user changes an input parameter manually, always retaining its original value, whether blank or defaulted programmatically, This worked just fine before the upgrade, but has now broken all my reports.

Is this an actual bug or was there some change I need to make since upgrading to fix this problem? Thanks.

I am using Telerik Reporting for just printing in my windows service but what happen is that its showing a dialog box for printing and I am getting an exception. I have already defined a default printer name by my function. Any help would be greatly appreciated.

Exception :

Service cannot be started. System.InvalidOperationException: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

 System.Drawing.Printing.PrinterSettings printerSettings = new System.Drawing.Printing.PrinterSettings();
            printerSettings.PrinterName = GetDefaultPrinter();

            System.Drawing.Printing.StandardPrintController standardPrintController = new System.Drawing.Printing.StandardPrintController();
            Telerik.Reporting.Report rpt = new Telerik.Reporting.Report();            
            reportProcessor.PrintController = standardPrintController;
            reportProcessor.PrintReport(rpt, printerSettings);
