One of my recent requirements involved retrieving just the time portion of a records value, generally the we have the data type saved as a date/time format. First of all we want to show only time at rdlc report . so, this is easiest way to show time or if you want to show date.
First :: For Time.
=FormatDateTime(First(Fields!LoginTime.Value, “DS”), DateFormat.LongTime)
First :: For Date.
=FormatDateTime(First(Fields!LoginTime.Value, “DS”), DateFormat.ShortDate)
