I am a pure beginner in csharp.

In my report, I have to group the results of an sql query data and calculate the average min., max. and median (I have three grouping categories: category I, II and III). For the average, min and max I can use the AVE-, MIN- and MAX-functions.
To calculate the median, I found the following c#-script:

public static double Median(this IEnumerable<double> list)
        {

            List<double> orderedList = list
                .OrderBy(numbers => numbers)
                .ToList();

            int listSize = orderedList.Count;
            double result;

            if (listSize % 2 == 0) // even
            {
                int midIndex = listSize / 2;
                result = ((orderedList.ElementAt(midIndex - 1) +
                           orderedList.ElementAt(midIndex)) / 2);
            }
            else // odd
            {
                double element = (double)listSize / 2;
                element = Math.Round(element, MidpointRounding.AwayFromZero);

                result = orderedList.ElementAt((int)(element - 1));
            }

            return result;
        }  


As I am an absolute c#-beginner, I don't know how to pass the sql-result of each group to the median-function... :-( I would be very thankful, if someone could provide me any hint.

I need help getting started with Telerik Reporting. I‘ve read the documentation and I understand
almost everything except how to get started in Visual Studio. I would like to use the VS designer, and
integrate the report into my WPF application, using VS 2013. I understand I should be able to create
classes inside a reporting project, but how do I start this project? I tried creating a Telerik Reporting
application, but it creates a WinForms application that doesn’t seem to do what
I need.

There is documentation on the Integrated Reports designer in
VS, but the very first line of the documentation says “Double click on the
Report.cs file” – where is this file, and how is it created??? It also mentions to click on the Telerik Menu
-> Reporting, but all I ever see is Upgrade Wizard. The documentation says other options will
appear when the designer has focus, but How do I find the Designer??? This is very frustrating when you can’t get
past square one.

I am using Telerik UI for WPF version 2013.2.724.40, and Reports version 7.1.13.802. I’ve successfully added
references to my project, and binding redirects to allow the libs to load. I’ve also added a report viewer control to my
WPF UI. What I need help with is starting the designer in Visual studio, and how to create the report classes.

Thanks,

Randy

Hi Folks - I'm having problems with missing toolbox items.  Ive read over this article: Telerik Reporting Toolbox items are missing and done all the stuff but I still dont get any tools when im in report designer.  I'm using both Q1 2011 and Q3 2013 versions. (not all apps have been converted yet).  is that a problem?  when i R-Click the toolbox and do Show-All then I can see the sections but the items are all greyed out?  Im running Win64.  what does it mean when i can only see items greyed out in Show-All mode?

I have a vb.net application with an asp page that has a report viewer control on it. The problem is that when publishing the application, the icons does not show up as in the attached image.

The webserver is running Windows 2008 R2 with IIS7

web.config

report.asp

I am trying to design a report contains a start date and end date, which needs the start and end day of current month, I implemented the logic in a C# assembly and used it in standalone designer, it's works well in designer, but when I embed it in a asp.net web application, I got this error :
Object reference not set to an instance of an object.
at Telerik.Reporting.Expressions.FunctionNode.Eval(Object row, Object context)
at Telerik.Reporting.Processing.ReportParametersManager`1.CalculateValue(P parameter, Object definitionValue, IDictionary`2 newValues, Object data)

at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

If I replace the values of 2 parameters to static values like "2013-01-01", it works.
 How can I achieve this goal ?

We have designed our report with a chart as in the attached image.
We pass the data to the report manually.

Dim rpt As New ReportLibrary.Shipping.ShippingByShipperHourly
rpt.DataSource = ds

 
The report has a chart on the detail section. We want to filter the charge data based on the UserID in the dataset.
Basically, dataset contains data for several users. Each user is displayed and then its shipping activity chart is displayed along with it. Then the row for other user and its chart. 

I need some code, I can put behind the NeedDataSource of the Chart component where I can filter the required data based on the current user data being rendered.

Is it possible? If so, how can we do it?

thanks

When I try to use the html 5 report viewer, it attempts to hit the following URL.

http://localhost:58924/api/TelerikReports/clients/[object%20Object]/parameters

it returns 404 (Not Found)

If I open the link in the browser I get the following error.

<Error><Message>The requested resource does not support http method 'GET'.</Message></Error>

Hi telerik,

Using wpf reportviewer and telerik Q1 2013 SP1
I'm currently having an issue with localization in my solution. My report is in English by default and the additional language is French. When I debug the solution I don't have any problem but in release none of the fields will be globalized. Only culture related fields like dates are correctly globalized, the rest is all in english.


Please note that I have other reports in the solution whom will localize correctly while using the same pattern.

please is it possible to pass sessions as parameters for a telerik report on page load.
If yes how can i please go about it. Thanks
