WPF: Binding ReportViewer.Report to Viewmodel property

Hi,

First of all, thanks for adding WPF support to Telerik.Reporting. Love it so far and am actually using it already in a clients project.

This project is a WPF MVVM project. So, using the samples I added this to my View.xaml:

    
            <telerik:ReportViewer Name="reportViewer1" Margin="0" Report="{Binding Path=Report"/>

Now, the ViewModel object contains the property report:

    
                    private Report _report; 
        
                    public Telerik.Reporting.Report Report 
        
                    { 
        
                        get 
        
                        { 
        
                            return _report; 
        
                        } 
        
                        set 
        
                        { 
        
                            // Check if it's really a change 
        
                            if (value == _report) 
        
                                return; 
        
                            // Change Report 
        
                            _report = value; 
        
                            // Notify attached View(s) 
        
                            RaisePropertyChanged("Report"); 
        
                        } 
        
                    }

Since the report get's its data from a business method (using a Webservice), I've put the code to create the report in the constructor for the ViewModel:

    
                    #region Constructor 
        
                    public SampleReportViewModel() 
        
                    { 
        
                        // get data and create report here 
        
                        var report = new SampleReport(); 
        
                        var dataObject = myClass.GetData(); 
        
                        report.DataSource = dataObject; 
        
                        Report = report; 
        
                    } 
        
                    #endregion

Now, while this code works just fine when I put it in the codebehind for the View (xaml) file itself, it doesn't work when I'm using databinding my ViewModel to my View.

Any ideas on how to fix this?
Thanks!

Programmatically creating silverlight reports

I am following the example in the C# silverlight sample as well as the documentation on this page: http://www.telerik.com/help/reporting/silverlight-report-viewer-embedding_the_silverlight_viewer.html

I have an application I am modifying that has existing reports that are essentially paged data grids. What I want to do is create a telerik report to display the data in each datagrid. I am trying to use the technique in the ListBound report that uses the cars list. I have the data on hand in a dto list already, and am trying to pass the information to a report that will display in the silverlight reportviewer.

Here is my code - rptEventSummaryDataSource is an object that is inherited from List:

//Create the data source
rptEventSummaryDataSource theData = new rptEventSummaryDataSource(dataSource as List<IdentityEvents_DTO>);
//Set the report name
rptViewer.Report = "NLx.TelerikReports.rptEventSummary , NLx.TelerikReports";
//Set the data source for the report
rptViewer.DataContext = theData;
//Refresh to make the data display
rptViewer.RefreshReport();

I have the data sources defined in the same project as my viewer since I need to reference them, but my reports are defined in another project - NLx.TelerikReports - and the references have been set in my projects as well as the web project that launches the silverlight app. I also had to define the data sources in the reports project so that here was a definition with which to create the report.

Long and short of it is I cannot get anything to display and I have been killing myself on this for over 24 hours. Any help is greatly appreciated. What I need to do for a start is display Lists of already retrieved data and pass the list off to a report for display.

Displaying a dynamically generated Telerik.Reporting.Report

Hello,

I'm currently dynamically generating a Telerik Report in PDF format into a new window by writing the bytes to the response as seen below.

BusinessClass:

Telerik.Reporting.Report report = GenerateInspection(formDTO, "DCF", lastSection);

Telerik.Reporting.Processing.ReportProcessor processor = new Telerik.Reporting.Processing.ReportProcessor();

Telerik.Reporting.InstanceReportSource irs = new Telerik.Reporting.InstanceReportSource();

irs.ReportDocument = report;

Telerik.Reporting.Processing.RenderingResult result = processor.RenderReport("PDF", irs, null);

return result;

And in the controller:

InspectionRules ir = new InspectionRules(); //my business class

var result = ir.GetReport(id, WebSettings.GetDCFConnectionString, site);

this.Response.Clear();

this.Response.ContentType = result.MimeType;

this.Response.Cache.SetCacheability(HttpCacheability.Private);

this.Response.Expires = -1;

this.Response.Buffer = true;

this.Response.BinaryWrite(result.DocumentBytes);

this.Response.End();

return View();

This is producing a nice PDF report in a new window. However requirements now dictate for me to have additional UI elements around and in some case overlayed the report. My question is what is the best way to go about this? Do I need the HTML 5 Report Viewer? Is there a simple solution? I must have a portion that on hover overlays a div over the report with controls in it. Note that in my view/test below the <h1> does not display. Thanks for any help or suggestions!

My View:

@{

Layout = null;

}

<!DOCTYPE html>

<html>

<head>

<meta name="viewport" content="width=device-width" />

<title>Inspection Report</title>

</head>

<body>

<div id="reportViewer1" class="k-widget">

loading...

</div>

<div>

<h1>THIS IS A TEST</h1>

</div>

</body>

</html>

Reporting - EMail PDF Report Working Code

After going through the many posts and examples I finally pieced together a functional MailReport function which I call from an UI for ASP.NET AJAX web application. It is interesting to note the many ways of the process not working.

using System.IO;

using System.Net;

using System.Net.Mail;

using Telerik.Reporting.Processing;

void MailReport(Telerik.Reporting.Report report, string from, string to, string subject, string body)

{

string extension = "pdf";

System.Collections.Hashtable deviceInfo = new System.Collections.Hashtable();

Telerik.Reporting.TypeReportSource typeReportSource =

new Telerik.Reporting.TypeReportSource();

String smptHost = SMTPSender; //set this to your SMTP sender service host

typeReportSource.TypeName = typeof(IRReport.IRReport).AssemblyQualifiedName;

Telerik.Reporting.Processing.ReportProcessor reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();

Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", typeReportSource, deviceInfo);

string fileName = result.DocumentName + "." + result.Extension;

MemoryStream ms = new MemoryStream();

ms.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);

ms.Position = 0;

Attachment attachment = new Attachment(ms, report.Name + "." + extension);

MailMessage msg = new MailMessage(from, to, subject, body);

msg.Attachments.Add(attachment);

SmtpClient client = new SmtpClient(smptHost);

client.Send(msg);

}

Subreport not displaying parameter value

Let me try to explain:

I have a main report , let say: "Main sales report" -this report recieve a parameter that is the seller's name as a string- and I also have (inside de main report) a subreport with some totals and also with the parameter.field with the "name of the seller" so he can sign the report .

My problema is this: when the main report does not have data also the subreport does NOT display anything (of course the subreport query does not has data also) but at least I need the name of the seller (that I'm passing as parameter) displayed in the subreport -so the seller could "sign" the report (even when the report is empty).

Any help will be highly appreciated

David .
