Exception about can't find OpenXml.dll when trying to render to PDF

I have this code:

ReportProcessor reportProcessor = new ReportProcessor();

Hashtable deviceInfo = new Hashtable();

var source = new InstanceReportSource { ReportDocument = report };

RenderingResult result = reportProcessor.RenderReport( "PDF", source, deviceInfo );

On this last line (the RenderReport call) I get this exception:

The type initializer for 'Telerik.Reporting.OpenXmlRendering.Wordprocessing.WordprocessingReport' threw an exception.

at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck)

at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark)

at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark)

at System.Activator.CreateInstance(Type type, Boolean nonPublic)

at System.Activator.CreateInstance(Type type)

at Telerik.Reporting.Processing.ExtensionManagerBase.CreateExtensionInfo(String typeName, String extensionName)

Which contains an inner exception:

Could not load file or assembly 'DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.":"DocumentFormat.OpenXml, Version=2.0.5022.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

at Telerik.Reporting.OpenXmlRendering.Wordprocessing.WordprocessingReport..cctor()

This was working before I upgraded from Windows 8 to WIndows 8.1. I upgraded to the latest reporting version, which did not help. I am not sure why it is trying to access OpenXml when I am asking it to generate a PDF.

[Solved] Code-free report chart with chart series based on multiple columns

Hello,

I have the following data:
Type Time Value 1 Value 2

Type 1	2013-03-02 13:01:00	0	15
Type 2	2013-03-02 13:01:00	0	8
Type 1	2013-03-02 13:02:00	0	15
Type 2	2013-03-02 13:02:00	0	8
Type 1	2013-03-02 13:03:00	0	15
Type 2	2013-03-02 13:03:00	6	2
Type 1	2013-03-02 13:04:00	0	15
Type 2	2013-03-02 13:04:00	5	3

I wish to draw a line chart with the Time column on the X axis, and 4 lines, being {Type 1-Value1}, {Type 1-Value 2}, {Type 2-Value1}, {Type 2-Value 2},

So far i haven't succeeded in creating this chart. I tried using DataGroupColumn, manually defining series, etc.... but without luck. I am trying to do this from within the standalone report designer, so I can't use code.

Any help is highy appreciated,

Kind regards,
Stijn

Manipulate existing textbox value

Hi,

I have a report containing several textboxes in my header section all bound to a sqldatasource.

In of them I need to modify the value from a delimited string (item1;item2;item3 ...) to a string with newlines at each ;
item1
item2
item3

My textbox is bound to Fields.MyDataField

I have added an event handler

private void textBox4_ItemDataBinding(object sender, EventArgs e)

{

Telerik.Reporting.Processing.TextBox txt = (Telerik.Reporting.Processing.TextBox)sender;

Telerik.Reporting.Processing.IDataObject dataObject = (Telerik.Reporting.Processing.IDataObject)txt.DataObject;

_myDataMember = (string)dataObject["MyDataField"];

if (_myDataMember != null)

StringToList();

//Here I need to rebind textbox to the modified string

}

In debug mode I can see all my data field values in the dataObject EXCEPT from the one I need to modify??? This one is null. BUT if I let the report render I can see the values fine.

Apart from this strange behavior, assuming the data is there, how do I rebind my textbox showing my modified string?

Thanks,
Per

Reporting MVC4 + HTML5 - How to Pass Parameters

Hi,

I've started using the new HTML5 reportviewer for MVC but unfortunately the samples and documentation seems to be pretty lacking.

How do I pass across a simple parameter to a report? Either via a link - e.g.. a link to show an Invoice which contains the invoice id.

OR

Allowing user selection on a page and passing that to the report?

Stuff like this should be simple but there doesn't seem to be any documentation at all on it.

How to use HTML5 Report Viewer in ASP.net Web Forms application (not MVC) ??? Please help

Hello everybody,

I am losing my hair on this one. Notice, I have never used routing or MVC before, so I am probably missing something obvious. I have a classic Web Forms project and need to integrate the new HTML5 Report Viewer.

Actually, when I start the HTML5 report viewer, I get the message inside the viewer "Error registering the viewer with the service". The html page is configured as suggested in Telerik's documentation, I have created a controller named "ReportsController" (as in doc).

To make run this controller, I have added the following in the Global.asax :

protected void Application_Start(object sender, EventArgs e)

{

WebApplication1.App_Start.WebApiConfiguration.RegisterRoutes(GlobalConfiguration.Configuration);

}

and I have created a class named "WebApiConfiguration.cs" as follows:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Http;

namespace WebApplication1.App_Start

{

public static class WebApiConfiguration

{

public static void RegisterRoutes(HttpConfiguration httpConfiguration)

{

httpConfiguration.Routes.MapHttpRoute(

name: "DefaultApi",

routeTemplate: "api/{controller}/{id}",

defaults: new { id = System.Web.Http.RouteParameter.Optional }

);

Telerik.Reporting.Services.WebApi.ReportsControllerConfiguration.RegisterRoutes(httpConfiguration);

}

Notice, I made no changes inside the webconfig.file

If I type http://localhost:65483/api/reports in the browser, I actually get some xml code :

[{"name":"PDF","localizedName":"Acrobat (PDF) file"},{"name":"CSV","localizedName":"CSV (comma delimited)"},{"name":"XLS","localizedName":"Excel 97-2003"},{"name":"XLSX","localizedName":"Excel Worksheet"},{"name":"PPTX","localizedName":"PowerPoint Presentation"},{"name":"RTF","localizedName":"Rich Text Format"},{"name":"IMAGE","localizedName":"TIFF file"},{"name":"MHTML","localizedName":"Web Archive"},{"name":"DOCX","localizedName":"Word Document"},{"name":"XPS","localizedName":"XPS Document"}]

But the HTML5 report viewer always tells : "Error registering the viewer with the service".

Really don't know what to do about this. As I said, I have no experience in routing / MVC.
Thanks a lot for your help and time,
Vlad

Q3 2013 + MVC: reportSource = instance of report

My situation in Q2 and old reportViewer:

<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>

<%@ Import Namespace="System.Data" %>

<%@ Register Assembly="Telerik.ReportViewer.WebForms, Version=7.1.13.802, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" Namespace="Telerik.ReportViewer.WebForms" TagPrefix="telerik" %>

<%@ Register Assembly="Telerik.Reporting, Version=7.1.13.802, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" Namespace="Telerik.Reporting" TagPrefix="telerik" %>

<!DOCTYPE html>

<html>

<head id="Head1" runat="server">

<title></title>

<style type="text/css">

html#html, body#body, form#form1, div#content

{

height: 100%;

}

</style>

</head>

<body>

<script runat="server">

public override void VerifyRenderingInServerForm(Control control)

{

// to avoid the server form (<form runat="server"> requirement

}

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

//IMPORTANT PART: setting source to instance of report passed from controller

ReportViewer1.ReportSource = Model.Report;

}

</script>

<form id="main" method="post" action="">

<telerik:ReportViewer ID="ReportViewer1" Width="100%" Height="600px" runat="server">

</telerik:ReportViewer>

</form>

</body>

</html>

Here I can create an instance of report on server and pass it to this view to render it on client.

While I'm waiting for documentation to come out, please help me how to do this in new html5 report viewer, and what is the best/recomended practice to render reports now?
