How to truncate date value coming out of DB

I have a method which fills-in the TextBoxes of my control.

The problem is, the date coming out has a TimeStamp, and I don't want to display it.

Is there someway I can format the value coming out of the datarow object so that it just returns a data?


public void FillPersonalInfoFromDB(string username, string connStringName)
    {
        string userID = CommonFunctions.GetUserIdGivenUserName(username);
        string sqlStatement = "select Birthdate, SSN from aspnet_PersonalInfo where UserId = '" + userID + "'";
        DataSet ds = CommonFunctions.ReturnDataSet(connStringName, sqlStatement);

        foreach (DataRow dr in ds.Tables[0].Rows)
        {
            //4/5/1974 12:00:00 AM is what this.TextBoxBirthday.Text holds after the line below runs
            //  I just want to show   4/5/1974
            this.TextBoxBirthday.Text = dr["Birthdate"].ToString();


            this.TextBoxSSN.Text = CommonFunctions.AddDashesToSSN(dr["SSN"].ToString());
        }
    }
