After upgrading to the newest reporting version, a report that had been working fine previously started giving the following error:

An error has occured while processing Report '':
Unable to cast object of type 'DataObject' to type 'Telerik.Reporting.Expressions.IHierarchicalData'.

After some experimentation I found that removing the textbox in the report's footer that used Count(RowNumber()) (to display the total count of detail items) the error went away and the report worked as before. How can I show the count without getting an error?

Thanks,
Mike

URGENT: Param bug returned in 2010

Dear Telerik support, the bug I reported back in 2008 (possible bug in params - Martin P - Posted on Aug 19, 2008) seems to be back in Q1 2010, when rendered in the web reportview and a trailing space exists an error is shown "invalid value. - Parameters: One or moreparameters are not set or have invalid values"

In a multi-value parameter ddl if just the value with a trailing space is selected you get the error but what is much worse is if all the ddl values are selected and preview is pressed the report displays but has automatically de-selected the param with the trailing space and displayed the data minus any calc which would've been taken into account from the missing val. You get no errors so do not know the report is incorrect.

As previously reported "An easy fix to place an RTRIM() in the dataset but think this is a bug an caught me out completely." AGAIN!!

I'm disappointed this has happened again and my client has been working with incorrect figures based on the reports

Regards

Martin

Reporting services designer

Hi,

I am interested in purchasing the reporting solution you have. But there is one feature that I really want and I need to ask before I start evaluating your product.

My customers always want their reports changed, I don't want to bother the programmers with this changes, what I would like is a tool that allows me to edit the reports server side and deploy them. Do you have such a tool ?

Thank you,

Calin

Fields.XXX.YYY does not work anymore

Hi,

We have reports in our project which were written in Telrik Reporting Q1 2009. While assigning a DataSource to a report we used to use an entity as a source as:

                    rpt.DataSource = my_entity;         

And in the report I have TextBox with the value "=Fields.my_entity.FirstProperty".

This used to work well until I have upgraded to Telerik Reporting Q1 2010. Now when I set the value as "=Fields.SomeValue" it works fine. But I can not use any property of the "SomeValue".

Did Telerik remove the lazy loading of the entity properties, or could I fix it with a minor touch of code?

Regards.

Converting reports vb to c#

Hi, I have a class library of about 60 reports which are in vb. I'd would prefer the reports in a c# library, the .vb files are easy enough as there's not too much code but unsure about the designer.vb files...any easy way to convert them? If not, it's not a problem.

cheers

Martin

Grouping expression should not contain aggregate functions - Q1 2010

Hi,

We have upgraded Telerik reporting version to Q1 2010 from Q2 2009. Report rendering performance is very good. But, one of our report suddenly giving error like "An error has occurred while processing Table 'tblControl': Grouping expression should not contain aggregate functions.". The same report is working well in Q2 2009 version. We are using 'Table control' in report.

1st Row - Header
2nd Row - Detail
3rd Row - Footer (here is our Total field we placed ie. Sum(SalaryField))

What is the cause of this problem?
