It's pretty simple though,

C#

SqlConnection con = new SqlConnection("DatabaseConnectionString");
SqlCommand cmd = new SqlCommand("SELECT SomeColumn FROM SomeTable", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);

foreach(DataRow dr in dt.Rows)
{
    ComboBox1.Items.Add(dr[0].ToString());
}

-KR

See example:

using (SqlConnection sqlConnection = new SqlConnection("connectionString"))
{
    SqlCommand sqlCmd = new SqlCommand("SELECT column1 FROM tablename", sqlConnection);
    sqlConnection.Open();
    SqlDataReader sqlReader = sqlCmd.ExecuteReader();

    while (sqlReader.Read())
    {
        comboBox1.Items.Add(sqlReader["column1"].ToString());
    }

    sqlReader.Close();
}
