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

When the report viewer (version 9.1.15.731) initially loads the first two group lines show one font and the next two group lines show a different font.

 When we switch to print preview, it corrects itself for the entirety of the session.

The report also prints as expected (with the same font throughout).

See the attached image which shows the initial display of the report.

 Is there any known issue that is causing this?

Hi,

I'm using Telerik Reporting 9.015.324 (VS 2015, Windows 10 x64).  I have a PictureBox in the Detail section of my report.  I have its Value property set to a string field in my data source - "ImagePath" - which is returning file paths.  The images are different sizes and proportions and I need them all to fit within the margins of the report.  Additionally, there is a TextBox in the Detail section with text content returned by the data source - "Content".  I'm trying to use a User Function to enforce a maximum Height and/or Width on the PictureBox based on the actual Height/Width of the image file.

This is my height function:

That user function is bound to the Height property of the PictureBox.

When I preview my report I get an "Out of memory" exception almost immediately.

I'm curious as to why I'm getting this exception, but my main objective is to get my report images to fit within the report.

I'm open to other approaches.

Thanks much.

Hello,

I am trying to create a set of graphs. I don't know how many graphs I will need to present at designtime (could be anywhere from 1 to 5). I first attempted to do this by adding all of the charts to the designer with their different criterias set and then hiding the ones that I didn't need at runtime, however this left me with seemingly random blank pages at the end of my report. I tried to change the report's detail height both at runtime and designtime to no avail.

Next, I took the programmatic approach. I attempted to follow the instructions here but couldn't figure out how to make this work with a pie chart - the graph would show up but the slices of data would not. I gave up on this because I figured it would be more effective to do this at designtime.

Now I'm at the designtime approach. I put the graph in a table, and I am able to repeat the graph for every row of the table, but I don't seem to be able to change any properties of the graph based on the row that it's on (I need to change the title, filter criteria, etc). There also seems to be some overlapping issues.

What is the correct way to go about this? I have read this thread (and the corresponding help articles), but the thread just isn't detailed enough for me follow, and the help articles don't give much of an explanation either.
