Hi,

I am trying to Implement the RedisStorage in my application which uses Telerik Reporting but doesn't seem to get any hold of it. Can anyone please help me how to use it.

I found some bits of code from long ago but still can't figure it out.

Any up to date clear code You could give me ?  I am using Angular/.NET core 5.0.

I am putting the report in the wwwroot and setting to copy always so the report seems to be there. The report has no parameters.

I get the error below

   [HttpGet]
        //https://localhost:44374/reports/testreport
        public string TestReport()
        {
            string webRootPath = _webHostEnvironment.WebRootPath;

            var rptName = Path.Combine(webRootPath, "Reports\\AllForms.trdp");
            var report = new Telerik.Reporting.Report { DocumentName = rptName };
            var instanceReportSource = new InstanceReportSource { ReportDocument = report };

            var reportProcessor = new ReportProcessor();
            var result = reportProcessor.RenderReport("PDF", instanceReportSource, new Hashtable());

            return "xxx";
        }

The current data set presented in the report did not produce any significant content, so no pages were generated. If you need to see the whole report content, including blank pages, please contact the report author.

Hello,

We have a dynamic report book we create for one of our reports. It has been working for several years. 

We just implemented load balancing and had to change our "ReportServiceConfiguration" to use MsSqlServerStorage instead of FileStorage. That works for all of the other reports except for this report book.

When you run the reportbook it behave strangely, sometimes it will display a few pages, other times it will get an error "index out of range exception". It is as if something is cached and it gets confused when switching servers. 

We are using ASP.NET MVC.

Any suggestions?

Hi,

I've set reportHeaderSection.Visible to false.  The contents of the page are blank but the reportHeaderSection still remains as a blank page.

How do I hide the entire section to remove the blank reportHeaderSection page?

Thank you for your help.

Hi guys,

I currently have a problem with the PageCount in a very specific situation.

I have a Report made in the Visual Studio Designer. This Report has a different Subreport based on a Parameter.
This Report is in a ReportBook in these variants with different parameters.

And this ReportBook is displayed in a ReportViewer.

Now the PageCount isn't always correct.
With always I mean, some versions of the Report have the correct number, some don't.

If the Report is not in the Book, the PageCount is correct.
If I try the same with a ReportBook in the Standalone Designer, it is also correct.

The PageNumberingStyle is set to ResetNumberingAndCount, so that can't be any problem.

Since it's a big C# project with Database connections, it's hard to give the whole code and just some snippets aren't relly informative.

But has anyone any idea what could help or how I could count the pages without the build in function?

Greetings Benedikt

I'm using HTML5 Webforms Report Viewer, and I want to create multiple instances of the same report using the ReportBook. Here are my codes:

var myReportSource = new Telerik.ReportViewer.Html5.WebForms.ReportSource();

myReportSource.IdentifierType = IdentifierType.TypeReportSource;

myReportSource.Identifier = typeof(myReport).AssemblyQualifiedName;

ReportBook reportBook = new ReportBook();

for (int i=0; i < jsonObject.Count; i++)

{

        reportBook.Reports.Add(new MyReport());

        reportBook.Reports[i].ReportParameters["Field"].Value = jsonObject[i]["Field"];

}

ReportViewer.ReportSource = myReportSource;

Question:

1. How do I assign the Report Book to the report source, then to be assigned to the report viewer? 

2. How do I set the "Mergeable" property to "false" for the report parameters?

Note: 

I have tried the approach from https://www.telerik.com/forums/two-of-same-report-in-one-reportbook-different-parameters, but I got an error "Cannot Implicitly Convert type InstanceReportSource to Html5.WebForms.ReportSource

   I'm having a problem using the Telerik Reporting WPF ReportViewer control.  I'm using Visual Studio 2017 v15.9.38 along with Telerik UI for WPF and Telerik Reporting v 15.2.21.915 (latest version).  My application is targeting .NET 4.5.2.

   In my application, I need to allow users to generate printed documents from system objects.  For example, a Purchase Order.  The user creates the Purchase Order, then needs to print it.  I'm trying to use Telerik Reporting to do this, much like other applications use embedded Crystal Reports.

   My application stores the reports as a byte array/varbinary in an MSSQL database.  To test, I copied the sample Invoice report, and removed all data sources and everything except a simple line of text and image to make sure it renders.  Later on I plan on adding data sources and binding those to internal system objects.  My application handles the uploading of the report document and pulls it from the database and generates a Telerik.Reporting.InstanceReportSource before showing it.

        Dim rsTelerik As New Telerik.Reporting.InstanceReportSource
        Dim rPack As New Telerik.Reporting.ReportPackager

            rsTelerik.ReportDocument = rPack.UnpackageDocument(New MemoryStream(MyByteArray))

   This all seems to work fine.  To display the report I have a custom control that hosts the Telerik ReportViewer and passes the ReportSource via DataBinding with a DependencyProperty.  I've made it extremely simple just to test things.

            <Reporting:InstanceReportSource x:Name="rsInstance"/>
        </tr:ReportViewer.ReportSource>
    </tr:ReportViewer>
</base:TBaseUserControl>

   However the Visual Studio designer shows the ReportViewer control as a completely blank and transparent object.  See attached screenshot.  I've verified that I have references to both Telerik.Reporting and Telerik.ReportViewer.Wpf, and I verified that the References are set to copy local.  I dragged and dropped the report control to let it create the references.  I also verified that my Application.xaml has the Resource Dictionaries:

        <ResourceDictionary x:Key="keuUI">
            <ResourceDictionary.MergedDictionaries>
                <ui:ThemeResources />
                <ui:XamlControlsResources />
                <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/System.Windows.xaml" />
                <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/Telerik.Windows.Controls.xaml" />
                <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/Telerik.Windows.Controls.Input.xaml" />
                <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/Telerik.Windows.Controls.Navigation.xaml" />
                <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Fluent/Telerik.ReportViewer.Wpf.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>

   Both the VS designer and my application show the control as completely blank and transparent.  See attached screenshot from the application.  I tried uninstalling and re-installing the Telerik Reporting module, but still have the same issue.  I get information in the Output window about the control loading and some warnings about a Telerik XML package, but no errors.  I'm guessing that this is some kind of error with the References or DLLs since the designer won't show the control either.  Any suggestions?
