You can do like this (just copy paste the below expression code to your expression field)
=First(iif(Fields!ID.Value = 2,Fields!Name.Value,"empty value here"), "DataSetPatientInfo")
and it will work
You dont need to include the "First" if you are using "Table" design to bind the dataset, for Textbox "First" is needed along with the dataset name.
Please let me know if this doesn't works.
