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.

(I'm using Telerik Reporting R1 2018)

Hi,
Is there a way to remove empty reports from a ReportBook ?

Thank you

 

Before R1 of telerik reporting, I was doing something like this :

 

With 

EmployeeName     Size     ManuCode

Name1                      1          ABC
                                  2          DEF

Name2                       3         GHI

I have grouped the above table with using EmployeeName.
How can I get the below output. I want to act the EmplyeeName as table header.

Name1

Size     ManuCode
1          ABC
2          DEF

 

Name2

Size     ManuCode
3         GHI

 

Hi,

When I hit the "print" button on reportviewer I need to call a procedure which writes the date of printig into the database.

I cant seem to find an event of sorts that does it. Anyone have any solution for this?

 

Thanks in advance.

RDLC Reports Loading too slow even to fetch a single row from Mssql

I have created a telerik report which uses Norwegian characters in the report as well as in the csv data sources. But in the Report designer when I go to the preview tab I can see that some special characters that are from the csv data source are missing. Characters in question is 'ØÆÅ'. All the special characters in the report (hard coded) are shown correctly, only the characters from the csv file that is not shown. Hence I went through the Configure CSV data Source and I found out that when parsing the CSV , there also these characters are missing (Shown in the attachment). How can this be fixed or does special characters are not supported for CSV files?

I have 4 textboxes that correspond to a multi-select dropdown parameter.  The space for the textboxes is a set width on my report.  Depending on which options you choose from the parameter dropdown, the other textboxes visibility will toggle on and off.  I have also set the width of the text boxes to change depending on how many are selected (if 2 options are selected, each is 1/2 of the given space.  If 3 are selected, each will be 1/3 of the space.

My problem now is I need to set the location of the textboxes depending on what is chosen.  If the first and third text box are shown and the second and fourth are hidden, the first and third will each be half of the space.  BUT I would need the third box to scoot over against the first.  Now, it stays at its original location and creates whitespace, causing the 3rd box to go onto a second page.

box1 box2 box3 box4

box1_____box3____

Is there a way to make box 3 move to the left up against box1 if box 2 is hidden?

 

Thanks,

Phillip
