Hello,

I have Telerik Reporting v2.5.8.519 and have a ReportViewer on a SharePoint page.  I put this on using SharePoint Designer and it is working as it should.

The only problem I have is that I want to resize the ReportViewer to 100% of available space on the screen.  I can set the report height in pixels (i.e., Height="500px") which makes the ReportViewer 500 pixels high.  However, if I put in Height="100%" then the ReportViewer does NOT fill up the screen height.  It only fills up the <div> the ReportView control lives in.

How do I do this?

Thanks,

HI team

I wanted to know if its possible to change the culture of a report during the rendering process.

 

Say for example you are grouping by Country. When printing a given country the Currency symbol should reflect that of the country.

 

Do you set the culture of all the report items in the lower detail sections (and possibly any child  groups) in the item databinding event. Thats what first came to mind.

 

Some code would be appreciated..

 

Kind Regards

Hello,
it has been a long time since I got this error happening randomly on my production enviorment and not been able to solve it.... I got this error message when opening a report with 2 parameters (int, datetime) :

Value cannot be null.
Parameter name : Instance.......

Consider that there' approximatelly 400 ppl using this application, I don't know it if it's something related to concurrency or what... I can just say that one time it happens it continue till I do an iisreset

I got this problem with Q2, can't move immediatly to Q3 since we got scheduled deploys..... any suggestion?
Thanks
Paolo

 

Hi all,

My application includes a Telerik report for a client that has a printer with A3 printing capability. I have defined the PaperKind to A3, Landscape to False, and the Width to 42cm. The PaperSize (disabled in the Properties list) shows a correct 297mm x 420mm. In design mode everthing looks fine and I can add controls over the required width of the report.

However, when running the report in the WinForms ReportViewer the report splits my pages, spreading the columns over 2 pages. I suspect this is due to the fact that my default printer (attached to my development machine) does not support A3 printing.

Is this a correct assumption?
Can I change this setting so I can see the report on screen in A3 width?

  Hi, I have some reports implemented in WPF, with the Telerik ReportViewer, in there the user can export the report result to CSV, PDF, Excel, etc. but I want what he will can export it only to PDF, how I can configure?

Thanks

We have implemented a custom report resolver that returns an InstanceReportSource based on the report class name. The InstanceReportSource.ReportDocument is instantiated from our IoC container (Simple Injector) and all objects are injected into the report via a constructor as expected. Within each report we subscribe to the NeedDataSource event and retrieve the data from a repository instance that has been injected. However, when we attempt to retrieve data from the repository, the repository instance has already been disposed. The injected objects are scoped to the webapi request. I read in the forums that the processing of the report happens in a separate context. Could that be causing my issue?

We've used this approach for years with the WCF report service and it has worked well. How can we configure this to work with the REST report service? We are now using the WPF report viewer.

 

 

I have some dynamic variable in my ASP.NET web-form application in session, that will stored when user login. In session variable I have some user information and some connection string of some database which will be created dynamically at run-time. 

How can I pass these variable data to report to bind some control to display user information and show some data from SqlDataSource which connection string also passed form ASP page to report.

Hi Guys,

 

As per the title is that funciton thread save? When I'm calling this in a multi threaded app I get an exception on the rendering although all variables are declared locally. So my guess would be that it is not?

I have a main report that lists cities, and I have a subreport for each city that lists buildings of them. I mean, subreport presents the detail of buildings of each city od the main report.

I want to pass a parameter to each sub report, this parameter is a value of a textbox in the main report. I'm passing this parameter in the "detail_ItemDataBound" event (main report), and then I intend to read it in the subreport, in the "NeedDataSource" event. The problem is that the parameter that corresponds to the first row appers in the second row, and the parameter that is part of the second row appers in the third one.

What am I doing wrong? or Does it have any mistake those telerik events?

I apreciate your help.
