Hello Support Team,

we need in our reports a table of contents with page number of each chapter.

DocumentMap functionality is a very good approach. However, because we lack the access to the relevant page number of DocumentMap element.

One could perhaps provide a copy of IList <DocumentMapNodeModel> documentMapNodes in Class ReportViewer (WPF).

After rendering the report I could see the page numbers for the creation of the TOC.

Or is there perhaps a solution to our problem?

We are using the WebForms report viewer control on an .aspx page.  We are trying to modify our site to use a State Server session state model, so all of our session items need to be serializable.. we've successfully made our objects serializable, but we are running in to a Serialization error on the ReportViewer page, and can't get to the bottom of it, because the error is thrown by external code... 

Our report viewer page ends up throwing 

Exception:Caught: "Invalid name character in 'List`1'. The '`' character, hexadecimal value 0x60, cannot be included in a name." (System.ArgumentException)
A System.ArgumentException was caught: "Invalid name character in 'List`1'. The '`' character, hexadecimal value 0x60, cannot be included in a name."

Which leads to 

A System.Web.HttpException was caught: "Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode."

None of our code is placing anything in to Session for the Report ... the code works fine for "InProc" session, which leads us to surmise that the Report Viewer control is utilizing Session State somewhere.  How can we utilize the Report Viewer control in a Serializable manner?

Thanks

Hi,

We are using Telerik Reporting (HTML5 Report Viewer) as main reporting solution in our web application (html5, Angular.JS, KendoUI, not based on ASP.NET). As a long lasting Progress partner, the company I work for just migrated to OpenEdge 11.6 in order to use the Pacific AppServer, and all our API's will be exposed using the Progress way (REST / ABL Web App projects) and not the Microsoft way (WebAPI).

In this scenario, how is it possible to implement the Telerik Reporting REST Service so that it's hosted on the Pacific AppServer? Any idea is welcome!

If you need more information, please let me know.

Best regards,

Mircea

Hello,

I have a very simple scenario where I want to load a report created with the standalone designer in a WPF ReportViewer.

[Code Behind for Main Window]

            InitializeComponent();
            ReportViewer1 = new Telerik.ReportViewer.Wpf.ReportViewer();
            Telerik.Reporting.UriReportSource uriReportSource = new Telerik.Reporting.UriReportSource();
            uriReportSource.Uri = @"./yop.trdx";
            this.ReportViewer1.ReportSource = uriReportSource;
            ReportViewer1.RefreshReport();

The ReportViewer is shown with the correct theme but the specified report (yop.trdx) failed to load. The report has only a static textbox in it (no datasource bindings)

My xaml look like:

<Window x:Class="App2.MainWindow"
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                xmlns:tr="http://schemas.telerik.com/wpf"
                xmlns:telerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
                Title="MainWindow" Height="350" Width="525"   telerikControls:StyleManager.Theme="Vista">
             <Grid>
        <tr:ReportViewer x:Name="ReportViewer1" HorizontalAlignment="Stretch"  VerticalAlignment="Stretch"/>
    </Grid>

Could you please help me?

Thanks,

Hi,
I need to hide some columns in a table.
I tried some programmatically approaches saw seen in the forum but none worked for me.

At the end i try to filter column groups as suggested by admin, this work, columns are hidden but the table don't shrink its width and
blank pages appear in the report.

There is a way to hide columns (using columns Group filter) and resize table to avoid blank pages

Thank you very much

I have the need to print off files along with my report. for example, printing a sales order with a PDF file of each item on the order.

i see that image files work great so the concept would be the same, but to call the PDFs file instead.

I have read that we can add custom functions so was hoping someone could share some ideas on how this would be approached.

the PDFs would ideally be within a container so we could control where within the report they would print, but I would even take it printing on a new page.

So in summary, I want to add a pdf like I would add an image, specify a field in my query that contains the path to my PDF, size the pdf container and be done.

any ideas?

Hi All,

I am using the report processor in Telerik Reporting Q1 2016 to render a report directly to a XLSX, e.g.:

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

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

  var result = reportProcessor.RenderReport("XLSX", instanceReportSource, deviceInfo);

The problem is that the XML files inside the XLSX file container all begin with a Byte Order Mark (EF BB BF). This is causing one of my customer's open source libraries to fail on reading the XLSX file.

If I open the exported file in Excel and then save it again, the BOM are removed.

So, is there a way to prevent the generation of the BOM in the first place?
