Hello,

I'm building a report using Report Designer Q2 2012 but I have a problem with labels that are too close to each other. I want to hide them in the chart but I can't find a way to do that. So let me explain my scenario:

I have a table with 3 columns: ActivityName, DayNr and NrOfMessages. ActivityName can be many things, so the chart series must be dynamic. I use the property "DataGroupColumn" and assign it value to "ActivityName" and that way I have the dynamic series generated. But now I can't change the series appearance and change "ShowLabels" property to false. I can't make this report using code, it must be done in the designer and I can't use either the "IntelligentLabelsEnabled" as true because I lose a lot of performance. I have put an attachment with a print screen of my resulting graph so you can understand better.

Can you help me?

Best regards,
Paulo Mendonça

Hi All,

I am new to telerik view, I have been trying to learn it and followed the telerik video to design a Sales Dashboard Report.

After I complete the Cross tab report and want to see the report designed so far and click Preview, I am encountering the below error:
Do not know what is the problem. The Error is as below:
"An error has occurred while processing Table 'crosstab1': Value of Top/Bootom  filters evaluate to integer"

Please find the code generated by the designer below:

Hi there,

I've created  a set of reports, most of which have a chart and a grid.
The reports pull data from a SQL data source, and pass in a StartDate and EndDate parameter.
I've set these up as Report Parameters, and these are visible when viewing the report as users will need to change date ranges.

The report parameters have a default value, i.e. I set the value in design time using a function. This sets StartDate to first day of the current month, and EndDate to last day of the current month.

However, when changing the values of these parameters on the report viewer, it seems to always use the design time set values, the value the user enters is never used.

Why is this? Should I be setting the default value in another manner?
I've tried setting 'Value' in the ReportParameter Collection Editor from design mode in VS2012, and I've tried setting it in the constructor of the report after InitializeComponent.

Hello,
the enclosed code was working with the 2011 Q3 version of Telerik Reporting but not with the 2012 Q1 version.
The idea is to define a class that inherits from Telerik.Reporting.Report and to base the reports on this class instead of the Telerik one. The goal is to put in this class code that is common to more than one report to avoid duplicating code.
So I define a class like this: And now my report inherits from MyReport instead of Telerik.Reporting.Report.
The problem is now that every time I change something in the designer and click on the preview tab, I have an error message that says:


And the call stack is:


In C#, I had to close the designer and open it again to make it work. In Oxygene (Delphi Prism), I had to close Visual Studio and open it again to make the designer work again; otherwise, it displays a black page with just a rectangle!
It's really a waste of time to work this way

I have a report designed while using the Demo version of the reporting software.  Upon purchasing/upgrading to the latest Telerik reporting, the report is no longer viewable in the VB.NET design mode.
The screen is filled with over 200 errors like: 'Object of type 'Telerik.Reporting.Drawing.Unit' cannot be converted to type 'Telerik.Reporting.Drawing.Unit'. '  All errors are linked to the designer code.  The program functions correctly, when running, and the 'errors' all show as only warnings when building the solution. The reference in the project is Telerik.Reporting v3.2.9.1211.

The errors all point to a line like the following:


Is there any way to salvage the report, so that I can modify it using the designer?

I have downloaded .trdx file from my web application to client machine
after changes being done from client in trdx i want to save this updated *.trdx on server
is there any way to do it using telerik report designer(standalone)?

Please help me out i am stuck with this.Its requirement of client.
So Please tell me how is it possible using telerik report designer.

Thanks in advance

Hi.

We have a Silverlight ReportViewer that talks to a WCF Report Service.

This report service looks implements "ApplicationPath" which according to its description should allow relative report file names when the silverlight viewer requests to render a report.


Our silverlight reportview uses standard binding to the "Report" attribute


The report renders correctly when "ReportName" is

• a fully qualified name that represents a report stored in a loaded dll on the server side
• "C:\ProgramData\OurApp\Reports\MyReport.trdx" - a fullName file path for a report stored on the server file system

Dear team,
I set a font family to a textbox in my report and when it render in my local machine it display the right font but when i run the report in the online website it get different font family and i don't know why.
kindly check the attached snapshots.

Mohammed
