We are binding our reports through the code-behind.  I need to create a drillthrough report.  I have watched the video, and set up the Master report action correctly -- I selected the child report using the "Select Report Document" and I created the target report parameter. On the Child Report, I have created the parameter to match the one specified within the master.

However, on my child report, I cannot figure out how to access this parameter. It is not being passed into the constructor (get an error if I force the constructor to accept a parameter) and the "Load" and "Init" events of the child report do not fire.  The value of the Report.Parameter I have defined is null.

How can I access this passed-in parameter value?

Hello

We are working on optimizing our reports, and after some investigation it turns out, reports with more than 1000 rows take too long to render.



We have modified our queries so fetching the data is actually neglectible compared to the actual rendering time. Both Excel and CSV produce very similar results, so it cannot be due to some formatting issue. There isn't any conditional formatting applied to the reports there is only a table with 14 columns in the details section.
The computer specs I'm testing it on: Core i5 3.2 GHz, 8GB RAM, 240 GB SSD.

I know that similar thread exist, but I've read in the release notes that rendering performance has been significantly improved in this version, so that's why I'm puzzled.

Regards,
Roland

Hi All,

I am trying to create a drill through report in a new window in a winforms application.  I know that I can set up a drill through to the same report viewer, but often the users like to see both the original report and any sub-reports side by side.  Is there a way to get the field name and value and perhaps other data for the same row in a VB or C# program when a user clicks or double clicks on a data item?  I could then use that data to create the other report.  Alternatively, is there a way to use the drill through action to create a spawned report in its own window?

Thanks in advance for any help.

Hello,

I need to set scale unit and/or step properties based on expressions for datetime scale. The reason for this is because my charts' time axis (x-axis) vary based on report input parameters (from date and to date).

Moreover, axis labels and grid lines should be able to dynamically reflect a timespan of an hour as well as a timespan of several months. 

Doing this programmatically is currently not an option. Are there any ways to achieve the above in Telerik Report Designer?

 

 

Hi,

 

I want to hide header and footer of main report, in subreport.

Ignore header and footer of main report, in some of sub reports.

We are using Telerik Reporting 2015 Q2 using HTML5 MVC Viewer and REST Web API services.

Everything working fine and the report rendered correctly and exports fine. Event the print functionality is working great.

But when clicking the print preview button for single page report, it fails. From browser console we see that the request receives 400 response.

The same print preview works when the rendered reports has 2 pages or more.

We are using SQL Server Database for caching.

Are we missing something?

I'm trying to use two sqlDataSources on a single report.

 So farI have this piece of code where the Datasource is binded to the first sqlDataSource.

 

 

I want to know if there is a way in order to tell the report that whenever I set the value of an htmlTextBox I can use the sqlDataSource other than the one set on this.DataSource.

 

Thanks.

what's wrong? 

thanks

Hi,

 We are trying to pass the data source query for the Telerik report as a parameter, at present we have option to build data source query during report creation in stand alone designer and the query is hardcoded inside the report(trdx file) when viewed from report designer or dot net application.

 

But we want to build the source query filters at run time in dot net application and pass them to the Telerik reports. I had raised a support ticket for this but haven't got an update from them, please share if you have some pointers to achieve this.

Thanks,

Daniel
