Hi Telerik team,

1. I need to validate expressions used in my report before report generation.
ex: = Parameters.Parameter1.Value / LineStyle.Solid, 

This expression gives me an error when generating report. I want to detect this very earlier stage. 

2. Is there any object type which keeps expression values or those expression evaluates in runtime? Can't I reuse expressions?

Hi,

Expressions are evaluated during the processing (http://www.telerik.com/help/reporting/designing-reports-life-cycle.html). Use the developer functions to perform some checks on the parameters and the fields in the expression - http://www.telerik.com/help/reporting/expressions-functions.html
