Hi,
We wanted to find out if it is possible to allow users to dynamically group data in a Telerik Reporting Report (the users are used to the group by features from the Telerik RadGrid/RadGridView). The users want to be able to select 1 or more columns in the report to group the data by, is this possible? Some times they will just let the report generate without adding grouping.

Hello jgill,
I have attached a sample project to illustrate dynamic grouping with Report Parameters and the following grouping expression:
=IIF(Parameters.Grouping2.Value is null,"",Fields(IsNull(Parameters.Grouping2.Value, "Sales")))
Just to note that the default Sales field will not be used, it's added to avoid error while evaluating the expression.

Hi Peter,
We have similar requirement as stated here.
I downloaded the sample code you have provided but was unable to run it in visual studio. Its shows an error "Object reference not set to an instance"
Can you please provide us the complete running project & not just the class files.
Regards,
Simon

Hello Simon,
We've not been able to reproduce the error you've encountered. Probably you forgot to rebuild your project after placing the sample report and classes in it? Anyway find attached complete project using a web application with the asp.net report viewer.

Thanks Steve! I wish there were more examples like the project you provided somewhere that was easily accessible. Like in the code library! While I don't have the same problems as the above poster, what you provided gave me some ideas that will help me.
