I have an issue with SSRS. In a filed called "InformacionDirecta" from the dataset "Solicitud" I have the following expression:
=iif(Fields!ModifInfoDirecta.Value,chr(254), chr(168))
It works well and shows me the type of checkbox I want according the value returned by the field (true or false) but, when I add another dataset ("Dataset2") the report shows me an error that says:
"the value expression for the textbox refers directly to the field without specifying a dataset aggregate".
How could I solve that?
