Hi dlocc,
Thank you very much for your answer. I follow your solution, it is Ok. But I have some another problem.
There is error message "An error occurred accessing a data source." (there is not error number).
I noticed, if user's profile does not have value in field "User Name", such as "name.surname", on SharePoint profile, the error is occured.
Otherwise, if user's profile has value in field "User Name", the error is not be occurred.
Do you know about it?
Thank you very much again.
