I created a series of Telerik Reports over the last few months that are of the same general format.  Each category of report has a detail report as well as a summary report.  For example, we could run a detail report for multiple clients with our application rendering reports directly to PDFs using Telerik.  The application simultaneously produces a summary report for the group of clients we ran at that time.  This same basic process happens for each category of report.

Until a few weeks ago, the reports were rendered perfectly without issue.  However, now approximately half of the reports have begun to treat an entire group header-detail-footer block as a individual data row.  This leads to the group's header-detail-footer being displayed for every data row.  I used the same group block format for the other reports and those still render correctly and the code/design hasn't been touched in weeks.  We did upgrade to the Q1 2010 version within the last month, but if that was the issue, wouldn't it affect all of the reports?

I have included some screenshots that illustrate the problem.

Thank you.

It does have something to do with the conversion from Q3 2009 to Q1 2010.  I dug up the Q3 version of the reports are they still render perfectly.  As soon as I convert, they begin behaving funky.  I now believe it has something to do with the datasets. 

After converting to Q1, my old datasets are still there on the surface, but if I try to modify a report's datasource properties, the datasets are no longer available as a datasource in the project, even though I am looking right at the dataset in the solution explorer.

Are there types of datasets that are no longer supported by the Q1 release?

Hi Andrew Volz,

Your question has already been answered in the other thread you've opened. Please, see our answer there for more information.
Since Q1 2010 DataSet is no more the preferred type of data source object. Instead we have introduced the new Data Source Components and this is the suggested way to proceed from now on. You can still use DataSet as a data source but you should create it by yourself. As you have correctly noticed the ObjectDataSource is the way to go.

Anyway if your reports display data from a database, instead of using DataSets and DataTables we suggest using the SqlDataSource component that is designed to work especially with Telerik's reporting engine thus offering much better performance.

All the best,
Steve
