I am evaluating the reporting functionality and I really need some help on binding a custom dll.  

This is what I have done so far.

1) Created a .net dll with the following code.  The dll is in the same folder as the trdx file

namespace ClassLibrary1
{
    [System.ComponentModel.DataObject()]
    public class Person
    {
        public string Name { get; set; }
    }
}

I added the data source to the trdx file as follows

<DataSources>
    <ObjectDataSource Name="ClassLibrary1" />
  </DataSources>

 

When I open the project in the Data Explorer I only ClassLibrary1.  I expected to see the object Person and under that the Name property.  I opened the Configure Object Data Source window but both tabs are blank.  

I have spent hours reading the forum and the pdf tutorial and just cannot figure this out. I must be missing some simple point on this. Any help would be appreciated.

Better yet does anyone has a simple example they would like to share? 

 

BTW: 

I also tried making a dll with a DataSet with some tables using the designer in visual studio but no luck with this either.

 

 

 

Hi

I am using Q2 2014 SP1 of Telerik Reporting.  My report currently contains a single Graph in the detail section.  It has a barSeries and two lineSeries.

However, there are times when I only want to show one of the two line series.

I'm binding the graph to a strongly typed list of objects and the object has a property on it that will let me determine if I want to hide the line series.

 

My specific example is this:

I am already binding my report's DataSource property to ReportItem.DataObject.BowlerValues  (this is my strongly typed list).

My graph might need to show Planned (bar), Forecast (line) and Actual (line) values.

A BowlerValue object has a property on it called "ShowForecast".

If ShowForecast is false, I will want to hide the Forecast Line Series.

 

How can I do this?  Can I use Bindings in any way?

Thanks,
Brent

Hi. I have two reports that have the same page header, data sources, and etc., but different page footer. I need them to be in a single one report, because I need it to print them together.

Here's the thing. In my view I was using:

var typeReportSource = new TypeReportSource() { TypeName = "../Reports/Report1.trdx" };
typeReportSource.Parameters.Add("IdYear", (object)(Convert.ToInt32(ViewBag.IdYear)));

@(Html.TelerikReporting().ReportViewer()
       .Id("reportViewer1")
       .ServiceUrl("../../api/reports")
       .TemplateUrl("/ReportViewer/templates/telerikReportViewerTemplate.html")
       .ReportSource(typeReportSource)
       .ViewMode(ViewModes.INTERACTIVE)
       .ScaleMode(ScaleModes.SPECIFIC)
       .Scale(1.0)
       .PersistSession(false)
)

And I had the same for Report2. But now I need to have them both in a single Report, and I've read that I can use ReportBook.

The examples I found show code like this:
 reportBook.Reports.Add(new Report1());
 reportBook.Reports.Add(new Report2());

But I am working with the .trdx files, not with the Visual Studio Designer. So I can't figure out how to do it. I found some reads about Activator.CreateInstance

I need some guidance. I am kind of stucked here.

Thanks in advance.

Hello,

 this is my scenario: WPF application with ReportViewer. My report uses a objectDataSource and displays a table with data. The DataMember (method which loads the data) expects 3 parameters: dateFrom, dateTo and a list of strings). I would like to select these parameters with custom input controls and pass them to the report. I don't want to use the built-in parameter selector because it doesn't fulfill my requirements.

 

So it is possible to pass parameters to the report? If I follow the documentation the DataObjectSource is created multiple times (and the data is loaded multiple times) which I don't understand because I only have one ObjectDataSource in my report!

 

Any help would be appreciated!

Does the new viewer support reports in a class library? I thought this may work, however I am receiving this error:

Type 'Telerik.ReportViewer.Html5.WebForms.ReportSource' in Assembly 'Telerik.ReportViewer.Html5.WebForms, Version=9.1.15.624, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' is not marked as serializable.

 This is the code I am using to display the report. 

Thank you

Scott

Hello Telerik team, 

This issue focuses on one that arises when attempting to export a report in CSV format. 

 As you will see from the attachments, we have a report where two totals are listed on the last two rows of the Report Viewer.  When this report is exported to CSV, those totals are instead duplicated numerous times as two additional rows to the right of the report.

 

 Several files are attached and I believe they will speak for themselves.  This is a significant issue for my company and we are hoping to be able to solve this issue in the very near future. 

 Please let me know if there is a way we can remedy this problem ourselves.  All of the relevant files are attached. 

Thank you for taking the time to review our problem, and we are looking forward to your prompt responses and feedback.

Warmest regards,

I am having trouble adding a sub report to my report.  I have created a subreport web page (VB.net).  Here is the code that works for adding the details but the subreport doesn't get displayed.  The top table is the subreport.  Any help is greatly appreciated.

'bottom table
Dim rptReport As New rptMSVS
rptReport.DocumentName = tmpStartDate.ToString("MM.dd.yyyy") 'tab name
rptReport.DataSource = dtBottom

'top table
Dim rptSummary = New sbrSummary
rptSummary.DataSource = dtTop

Dim reportBook As ReportBook = New ReportBook
reportBook.Reports.Add(rptSummary)
reportBook.Reports.Add(rptReport)

'add the sheet to the report
rptMSVS.Reports.Add(rptReport)
rptMSVS.Reports.Add(rptSummary)

 

'display the Report
Dim rptProcessor As New Telerik.Reporting.Processing.ReportProcessor()
Dim instance As New InstanceReportSource()
Dim hshTable As New Hashtable()
instance.ReportDocument = rptMSVS
Dim result As Telerik.Reporting.Processing.RenderingResult = rptProcessor.RenderReport("XLS", instance, hshTable)

rptViewer.ReportSource = instance
rptViewer.DataBind()

I recently upgraded from Q1 2014 to Q2 2015 and now I am having issues on any reports that I prompt for parameters. In the past when I opened the report, I would get an error, but the user could enter the parameters and then properly run the report (See ss1.png). Now I just get an error and no parameters (see ss2.png). Here is what I use for my display code in my MVC Razor page:

 

 

What am I missing? The only thing that has changed is the version.

Hi

I've downloaded trial verion of telerik reporting to try functionality what I need. On demos I haven't seen option to export report to DOCX (i don't know why) also when I tried to export it manualy with RenderingResult result = reportProcessor.RenderReport("DOCX", reportToExport, null); but  I've always seen "DOCX rendering format is not available." message.

Could the trial version be a reason?
Have someone had issue like this?

Best regards
Waclaw
