I am trying to get rows where the filed "Cost" does not have any value, formatted in red.
So far I have tried in several ways but the one that I thing should be closer to the right one is stye following applied to the detailed section of the report:

Expression: Field.Cost
Operator:      =
Value:           =" "

I also tried with value: = Null

but I get errors in the report and no formatting! 
The error I am getting is in the attached picture, however it says "Cannot perform = operation on System.Double and System.String. Same with "Like"
What should I do to get this expression correct?

Thanks,
Felice

Hello Every1 and telerik!!!

I am using visual studio 2010, i have several reports in my app. all were working fine, then i upgraded  to 8.0.14.507. after that up gradation, no report generates, just a blank page. A break point on "RenderBegin" event can not be hit. then a new version of telerik released on 18 june, i tried that also but same result.

then i started trying down-gradation, it worked on version 8.0.14.225. but after few days same result again. now it works only on version 7.2.14.127  but i afraid it will behave like before again.
Refer to attachments for a reportviewer code. it is wasting so much time of mine. anyone with help please.

thanks

Hi,

I'm trying to create a report with summary of all rows in the table like the example below.

emp_id   emp_name
1                  a
2                  b
3                  c

emp_count: 3

I tried to add TextBox for emp_count with aggregation to emp_id column but because of the textbox doesn't have DataSource, the value was 0.
When I added DataSource to the report, the emp_count's value was correct but the table's data displayed twice. I also tried to use RowCount("reportName") function
but it didn't work. 

Any suggestion?

Thanks

Hi,
I can not open example Employee Sales Summary.trdx file with Report Designer Q2 2014. It show : Object reference not set to an instance of an object.
You can refer attached file for detail. For other trdx files, it open correctly.

This err also appear with some report file trdx created with Report Designer Q1 - 2014.

Hi,

Currently I am investigating the testing facilities available for Telerik specific reports.

As part of the current Telerik Testing Framework, what coverage is offered to develop coded unit tests (C#) around a Telerik instance reports or Telerik URI reports? 

Kind regards,

Jean-Paul

Hi Team,

When we expect text justification option in textbox and htmltextbox ? Every clients of my company require this. Is there any other workaround available ?

Thanks in advance.

I try to run the report on the report viewer with a lot of calculation. I extended time out on data source. But after a while I got a blank screen.

Do you have any suggestions.

Thank you,

ASP MVC 4 using old aspx not razor
Bootstrap css
confirmed  /api/reports/formats returns json
so rest service webapi is working

/Reports/telerikReportViewerTemplate.html
returns correctly in the browser

All I get is the following "Telerik.ReportViewer.Mvc.ReportViewerBuilder"


Here is my mark-up

Using the most recent version of Telerik Reporting  7.0.13.426 with the visual studio 2012 dark theme has an issue where the context menu is black on black.  Does anyone else have this issue?  All other context menus across the project are fine (rdlc's, solution explorer, etc)
