I need to use an expression result multiple times. Do we have any variable to hold the result of the expression result to be used later?
In my scenario, I am using the expression Sum(Fields.Field1 * Fields.Field2) for four report items(textboxes). I think it will get evaluated for each of the report item( 4 times in my case) which can be time consuming. So I was wondering if there is any option such as a temporary field(like hidden field in ASP.Net) or any alternative variable to hold the expression result and then use it for the next time it is required.
Please suggest !
