Showing only Date in ListView

Hi,

Anyone know how to format the Date Time Picker in C# to show Date only using DataReader in ListView. Below is the part of Code

OleDbDataReader dr = cmddr.ExecuteReader();

                while (dr.Read())
                {
                     dp_expDetail.Value = Convert.ToDateTime(dr["e_date"].ToString ());
              }

the above code is  showing date as well as time but i want it show only date
