front setting

hi all,
i would like to check if there's any possible to set the textbox front in such a way
Date : 15/04/2005
which means the label is bold and the date is normal. cos when i join them together the coding goes like this
="Date : " & First(Fields!pat_dateOfBirth.Value, "PatientDB")Ya prolly got this one surrounded, but if you are using text boxes, just use two of them, and set fonts for each, and forget the "date:" part in the expression.sql
