MS SQL Server Report Builder 3.0 how to convert Parameter (clarion date) input to display as date type on report.

I am creating a report based on data from joint tables. Data in the report is filtered by Parameters - variable dates range which are passed from external application as a clarion date.

I would like to display on my report the values that were entered to parameters @date_from and @date_to in clarion date format but converted into date format.

The T-SQL code that converts the clarion date is: 

cast ([date_from] - 36163 as datetime)

but when I use the above code it is displayed on report as text.

In Report Builder I understand an expression should do the conversion:

=CDate(Parameters!date_from.Value)

but that returns an #Error in the actual report.

What am I doing wrong?

******EDIT******

Correct syntax in Report Builder 3.0 for code Simon_Hou has supplied:

=DateAdd(DateInterval.Day, Parameters!date_from.Value, #12/28/1800#)

or =DateAdd(DateInterval.{Hour/Day/Month/etc.}, Int Value, #MM/DD/YYYY#)
