Hi,

I set up a Telerik Reporting WCF Service, a silverlight client to show the report, created a report, succesfully added the WCF report service reference to the client, and verified that it is called. Everything works up to that part.

But how do I implement the methods of the IReportService interface? I can't find examples of what I'm supposed to do. Below is the code that I guessed so far from trial and error, but this gives a xaml error.

Is there an example of how to implement a WCF reporting service?
 
In specific the method: GetPage, what is the byte[]?The manual says "Gets or sets the Byte array that contains the current report page.", but is that in pdf format?

Regards,

Bayram

I tried to add an expression =PageNumber in the Report header, and it didn't show up.   

Shouldn't PageNumber be available in all sections?

I am using the reportheader to display [=Page #: 1] text instead of ="Page #: " + PageNumber.  Then with the reportheader hidden on other pages, I am using the pageheader to show the pagenumber text for each page with a smaller footprint.

Hello,

I need to do pie chart to show life cycle of different Pallets.

In database have values like below:

Pallet Lifecycle UsedLifecycle RemainingLifecycle
P100 100 90 10
P101 200 100 100

Am able to display Pie chart individually for P100 Or P101.
But how to show 2 charts for P100 and P101 in single report?

I used Datagroupcolumn as PalletId; but the series shown in single chart itself, ie;P100 and P101 in same chart.
How to show it in different charts?

Its urgent.

I have a report that has a few toggle visibilty sections in it and in most cases the toggle button does not print or show in the preview, but for some reason the is one section that shows and prints the toggle button.  Is there a setting somewhere that needs to be set so that it does not print?

Hi,
We are using Telerik Reporting Q3 2007. 
 
- How can i load a saved report dynamically at run time?
- Is there any progress about save a report definition in outer storage (like xml-file) 
- When will your Report object (Telerik.Reporting.Report)  be supporting serializing / deserializing with soap or binary formatter or other way to serialize.

Hello,

   I have a report and viewed in silverlight, my problem is how can I change the margin at runtime? Because the user has the option to change the margin anytime.

  Thank you.

I have a Table used to display an Address.  Not every user fills in every field and at diplay time i'd like to just remove the Rows that have no data.

I did this so far


This works fine, what I was thinking was that I could, in the databound event, loop through the Rows and see which, if any had no contents and jest Delete It?

Not sure where to start there though.

Hi,

I have applied conditional formatting to controls. On a specific condition I am setting Visible=False for a textbox1. When this condition is true textbox1 gets invisible, but the textbox2 which is positioned just after textbox1 is shifted to left and takes the position of textbox1.

I gone through following link and found that this problem was in 2009 Q3 release. Is it still persist? I am using version 5.0.11.316 of Telerik Reporting.

Please suggest me some solution.

I have gone through http://www.telerik.com/help/reporting/entitydatasource.html but am completely stummped. My code generates no errors but all of the reports are coming up blank.

Here is my code:

XAML Element:


LoadTelericReport() is called after the data source and page has been initialized.

The second part is the class that pulls from the Entity Framework:


Both sections are run fully, and AllEvents.ToList() is returning a full List<EventType> (if this matters it isn't called until after it has been bound to telericPersonReport.

As far as I can tell the WPF reporting front end just isn't displaying the List<EventType>, but it also isn't throwing an errors which seems strange. Is there something clearly wrong with my code, am I just completely off on how this works?

Thank you all for any directions you can point me in!
