I have been trying to use breaklines in the HTML Textbox in telerik reports (using Q1 2015 sp1 Telerik version) but 
is not being rendered as a breakline. As you can see in the first attachment (testReport_backend.PNG), I've tried \r\n, \n, replacing < with < and > with &rt; in both textbox and HTML Textbox but in the second attachment (testReport.PNG) the html tags are not being rendered like HTML tags.
What am I missing to make this work?

Hello,

 I have a report with optional parameters, but at least one needs to be specified to run the query (stored proc).

FromDate (Required)
ToDate (Required)
Invoice (Optional)
PurchaseOrder (Optional)
Customer (Optional)

 In this case, either Invoice, PurchaseOrder or Customer must be specified. I don't want the query to run if none of these are specified so right now I throw an exception from the stored proc if all are null, but this results in a non-user-friendly error message.

Thank you

I am using the Telerik Reporting with HTML 5 Viewer Q2 2015. With specific report it needs high processing i increased the timeout of the sql data source command to 600 seconds (10 minutes).

 When rendering the report in the HTML 5 Viewer i receive the following error :

 Internal Server Error
Timeout expired. The timeout period elapsed
prior to completion of the operation or the server is not responding.
This failure occurred while attempting to connect to the routing
destination. The duration spent while attempting to connect to the
original server was - [Pre-Login] initialization=112; handshake=27;
[Login] initialization=0; authentication=0; [Post-Login] complete=1;
The wait operation timed out

This error occurs just 40 seconds after pressing the preview button

On the FREB log i see that the timeout occurs on the ReportController GetDocumentInfo method.

 Any thoughts?
