I am currently working towards moving our report files into database storage. I have setup a custom resolver that is able to get the report from the id properly; however, when the subreport is loaded, it does not appear to be using the /api/reports serviceUrl. instead, it is looking in the root directory of the project in visual studio and not being routed through the Reports controller. Of course, the report is not there. What do I need to do to make the reports to evaluate on the serviceUrl to get it like the other reports? 

Here's my resolver:

public class DatabaseReportResolver : Telerik.Reporting.Services.Engine.IReportResolver
    {
        public ReportSource Resolve(string message)
        {
            using (var _context = new CommonDataContext())
            {
                var report = _context.ReportRecord.FirstOrDefault(x => x.UniqueName == message);
                if(report == null)
                {
                    return null;
                }
                var fileContent = report.ReportFiles.OrderByDescending(x => x.DateActive).FirstOrDefault();

                if (fileContent != null)
                {
                    var file = fileContent.File;
                    XmlReportSource source = new XmlReportSource();
                    source.Xml = System.Text.Encoding.Default.GetString(file);
                    return source;
                }
            }
            return null;
        }

       
    }

In my current project, ASP.NET Core 2 (on full .Net framework), users will have no use for the Navigate backward, Navigate forward, Toggle parameters, Toggle document buttons. These are disabled but I would like to remove them from the toolbar. Do you have an example on how to do this?

Thanks

Hi,

we try generating reports on the server simultaneously:

Parallel.ForEach(x, x =>

{

...

ReportProcessor.RenderReport(...);

....

}

and get the occasional exception below:

All the reporting assemblies are the latest.

Please help me on this. It is very critical For me

 

Hi, I am creating an invoice report that has a payment slip at the bottom of the report. The payment slip contains the Amount Due and the Address to mail in the payment. Customers detach the payment slip along the dotted line and send it along with their payment. The address on the payment slip should always show up through the envelope window. This can only happen when the payment slip always prints at a fixed distance from the bottom of the page. I've tried using a panel (that docks to the bottom of the page etc.) without any luck.

Can you please provide me some tips on how I can do this?

Thanks

Hello, for testing, I installed Telerik Reporting R1 2018 and configured the filtering in the parameter report. In the studio, everything works, but when you build and install on the server, the data is displayed all without filtering in Chrome and Firefox. In safari and IE work fine. Project ASP.NET 2.0 Framework 4.0.

I have a report that has a table that is populated from a stored procedure showing sales by contract - one line per contract.

I need to add 2 levels of groups so that I can show Sales by Salesperson within Shop with a page break on Shop and totals at both the Salesperson and Shop levels.

I have tried adding 2 Groups and moved the table to the last Group Header section but the grouping doesn't seem to be doing anything.  The report is not showing any Shop or Salesman details.  The design is shown in the attached image.

 

What am I missing?

Regards

Kevin

 

Hi,

I'm trying to create a graph with a few series on a numerical Y axis and date time X axis.
The Y axis is very simple with a fixed range and a known number of steps. However the X axis could have anything from a few values over a 5 minute range to a few hundred values over a 5 year range.

By default the graph appears to be configured to automatically set the scale, unit set to auto, but for a short range of values it just puts a label every minute and for longer periods it complains about having more than 5000 ticks.
All the documentation seems to suggest I need to set the unit and step values in the designer but this is not an option when I have an unknown range of values.

What do I need to do to get it to automatically calculate a suitable scale for the X axis.

I'm using Q2 2014 SP1.

Thanks,
Martin

I'm trying to incorporate the new InstanceReportSource into an existing program that I've inherited.  I understand the Visual Basic examples given, but I'm stymied how to apply it to a C# program that is using interfaces.  Using the older version of Telerik that came with the program, the code will compile and run (although the designer won't come up).  Upon upgrading to the latest release of Telerik reporting, I've gotten the designer to come up on some of the reports.  However, I've got a few that are flagging errors about the deprecated RecordSource.  Therein is my confusion.  My attempts to incorporate the InstanceReportSource seems to result in more errors and I'm at a loss.  I did submit a trouble ticket when I was first intially using the trial version.  The end result was to "use the Instance Report Source".

I'm currently using Telerik Q2 2012 SP1, Visual Studio C# 10.0.30319.1 and .NET 2010 4.0.30319

In addition to the code listed below, I've also included a screen shot of the error message(s).   Any help or direction you could provide would be greatly appreciated.  Many Thanks!!

Hi, I am working on Telerik Reporting version R3 2017. I got the output as expected and it is giving me report very accurately if all data is there. In some cases I am my Table wizards do not have Data in Datasource and as result it is creating an empty patch on report.
Let me explain: Lets say I have 4 table wizards

TableWizard1 - shows Customer with only with First Name
TableWizard2 - shows Customer with only with Last Name
TableWizard3 - shows Customer with only with Address 
TableWizard4 - shows Customer with only with Phone Number

All 4 table wizards getting filled by only one CustomerDetailsDataSource to make it in different tables I applied filters Lets say for TableWizard1, I applied filter if F_Name!= "" or for TableWizard2 I applied filter L-Name!= "". 

Now, my problem is if there is TableWizard1, TableWizard2 & TableWizard4 has some data and TableWizard3 do not have any data still it is showing an empty patch on  ReportViewer, Obviously on PDF also.
 
I had look on NoDataMessage but it seems like it doesnt work in this case. Can you please suggest how can I handle that?
Thank You
