I have attached a sample solution for your task. I have used two events and a global variable to count if the expression is valid.
You will need the AdventureWorks sample database which comes with the installation of the product. Just change the connectionString accordingly and you should be able to run it.
Let me know whether the proposed solution helps.

Thanks, yes i had done my solution like that but i wanted to do it automatically (for example with count function). So I have a question, Telerik's reports can be that automatically? the count function cannot count with conditions?
I think I'm gonna do my own function count and I will put it in my groups footer. When I do it, I will show you.
