Interaction Tag as an expression

[scoroop]

Hello,
we have a report with dynamic columns, that is on data band we have fields like Field1, Field2, Field3,... When we pass data as .NET object object contains records with values for records but also data that contains the labels for them - which are assigned to Text components in header band using expression. So far so good and it works.
Next stage is CSV export which is quite often used by our customers. I researched that if one wants to have proper headers in CSV a Interaction.Tag property in Text component in data band must be filled like this:
CSV: "MyLabel";
As long as it's static text it works for me. But now I need to assign it using expression just like I do with header band Text components. Could you please tell me how to do that? I mean how the expression should look like?
Thanks
