I need to create a report that displays the details (including all children) for a single entity. I've got a method on my Object context that returns a single entity and I'm setting my entity datasource to that method. At runtime, I'd like to set the datasource in code to the current entity (which should already have all the navigation properties loaded, reducing the # of trips to the database). 

I have a few questions:

1. Is it okay that I'm setting the datasource at designtime to a method that requires a parameter, but at runtime I set it to the entity (hence, no parameters needed)?

2. How do I show the details for the child collections? I'm guessing I will need subreports, but I'm not sure how to pass the child collection over. Will I need to use the NeedDataSource event? and if so, how do I use that and will I still be able to design the report using the designer?

3. How do I show/hide data? For example, one of my fields is a boolean value. Based on true or false of this field, I would like to show/hide (collapse) a certain area that displays several other fields. I read on another thread about setting the height of the details, but my data is in a panel (which I couldn't find a height property for).

Hello,

Parameters are not loading at first time or ReportViewer presents a "Report is unavailable or session has expired." error message. After pressing the "Refresh report" button report is always presented correctly.

It happens like once per several tries, but still and it is unacceptable in a business solution. 

Raport is generated dynamically, and all parameters are passed from ViewModel in this way:

 

We've already changed the default HTTPBinding settings in the ReportViewer



and in the webconfig where the ReportService is placed as well:



however the problem still exists.

Any ideas?

How can I display headers in crosstab?

Hi,

I have created a reports class library and used report wizard to connect to DB and create the report. As a result, it created the connection string in app.config of the reports project and the dataset thus created uses the connection info from the settings file.
The issue is when I publish the application to the live server, the app.config from reports project doesn't obviously get published. I had to manually copy that. How can I work around that?

Environment: VS2008, Q3 2009, C#

Thanks,
BC.

I'm putting a bottom border on my list items (using a panel) to separate them, but don't want to show this border on the last item, because I have another border at the end of the list. Is there a way I can check if the record being processed is the last one, so that I can set the border to none?

Hi,

Ive created a silverlight report that based on a parameter dynamically adds some report fields in code. So in my NeedsData event on the report definition I check a parameter and create some extra fields and then set the datasource for the report.

This seems to work fine to generate and print the report but when I use the silverlight reportviewer to save as pdf (or any save as format) then it appears I get a new instance of the report on the server (I can set a breakpoint in the constructor) but never get a needsdata event call. I tried moving my code to the constructor but it seems that my parameter is not not initialized yet in the constructor.

Where would be the correct place to dynamically add some report textblocks, etc. in code so that it works for both report generation and save as?

thanks,
Adam

Hello all, I'm using Telerik Report for the first time. Since we use other Telerik solutions, we opted to try it.

Here is my current problem. I created the Service in my server, where all my solution services are. I created a ClassLibrary with the report, and followed the tutorial to create the viewer in my Silverlight application. Now when I try to render/view the report I get an error: "Report is unavailable or session has expired."

I debugged my server, and both the report, and the data source (an object) are created. The report works fine in design preview. I checked asp.net session, and tried both StateServer and InProc sessions with the same error. 

As someone suggestion in this forum, I debugged with Fiddler and two calls are made, with the following response:

Fist call response:


Second call response:

But the above response did not help me solve the problem. What should I do, where should I look?

Hi

I am creating a report using Telerik Reports. I am also using DocumentMapText property for groups to display in the bookmarks section in pdf. But its not showing the hierarchy in the bookmarks according to the group. I have a top group with Region Name and I have ServiceTypes udner it. But Region and Service Types are being shown at the same level in the bookmarks and the same even in the reportviewer as well.

Please find the attached zip file containing the pdf and the report desginer and the code behind files and let me know where would be the mistake happened.

I have implemented by following the below url
https://demos.telerik.com/reporting/product-catalog/silverlight-demo.aspx

Thanks in advance
